Nova York lança Plano de Floresta Urbana com meta de alcançar 30% de cobertura verde em 2040

Nova York acaba de anunciar o seu primeiro Plano de Floresta Urbana (Urban Forest Plan - UFP).

Uma das métricas para se avaliar a arborização das cidades e florestas urbanas é a mensuração do chamado "dossel", que é a cobertura verde composta pela copa das árvores da cidade. Isso pode ser medido através de sensoriamento remoto e permite avaliar a expansão da arborização, áreas mais deficitárias de vegetação e planejar a ação da administração pública. Quanto mais árvores e quanto mais qualidade da copa das árvores - volume e densidade - mais eficiência na proteção da cidade para os extremos de calor e mais fixação de carbono.

O plano tem por objetivo expandir o dossel dos atuais 23,4% para 30%, em 2040. Para atingir o objetivo, o plano prevê conservar o dossel florestal atual, ampliar para ruas e espaços públicos e promover plantios em propriedades privadas. Também está no planejamento a mobilização dos nova-iorquinos a cuidar e proteger a floresta urbana. 

Isso é parte do objetivo do Plano de Floresta Urbana que a cidade de Nova York acaba de lançar, como parte de uma política de resiliência climática que começou a ser estruturado após a tragédia causada pelo furacão Katrina, em agosto de 2005, que assolou os EUA, causando milhares de mortes no país e foi devastador também em Nova York.

Com o UFP, a municipalidade pretende também atuar sobre o aspecto da Justiça Ambiental, corrigindo o déficit de arborização nas comunidades menos atendidas por infraestrutura verde. Segundo o plano, as comunidades objeto da ação prioritária de Justiça Ambiental contam com a cobertura de 19% de dossel, enquanto as demais comunidades possuem 26% de dossel.

New York City Announces Release of First-Ever Urban Forest Plan

Plan lays out NYC’s strategy to achieve 30% tree canopy by 2040 through protection, preservation, and planting of more trees

Read the full plan here.

BROOKLYN, NY – Today at NYCHA’s Red Hook Houses in southern Brooklyn, Chief Climate Officer Louise Yeung announced the release of New York City’s first-ever Urban Forest Plan (UFP): a comprehensive roadmap to preserve tree canopy, plant more trees, and cultivate an ecosystem of stewardship. Climate Officer Yeung, the head of the Mayor’s Office of Climate & Environmental Justice (MOCEJ), was joined by Deputy Mayor for Operations Julia Kerson, Department of Parks & Recreation Commissioner Tricia Shimamura, NYCHA Vice President of Sustainability Siobhan Watson, and the Executive Director of Trees New York for the announcement and subsequent stewardship activity on the NYCHA campus.

The UFP lays out the City’s goal of achieving 30 percent tree canopy by 2040. Today, the urban forest canopy shades 23.4% of New York City, covering roughly 45,000 acres — an area about the size of Brooklyn. Reaching this expanded canopy will help the City achieve broader goals of advancing environmental justice, mitigating the effects of heat, and improving quality of life.

“New York has always been defined by the dreams we dare to build together. Today, we’re planting those dreams in the soil itself,” said Mayor Zohran Kwame Mamdani. “The Urban Forest Plan is a commitment that no matter your neighborhood, you deserve clean air, shade in the heat of summer, and streets that reflect the possibility of our great city. Together, we’re going to grow a New York that is greener, healthier, and more beautiful for everyone who calls it home.”

“No matter where you live, work, or spend time outside, all New Yorkers know the immediate relief that comes from standing under the shade of a tree on a hot day. What may be less obvious is that trees are one of the most affordable and accessible ways to help adapt to a changing climate,” said New York City Chief Climate Officer Louise Yeung. “Yet for too long, New Yorkers of color in environmental justice communities have been left behind, lacking critical access to trees and all the benefits they provide. Expanding and caring for our urban forest is a matter of racial and environmental justice, and I look forward to bringing our first-ever Urban Forest Plan to life.”

“Our urban forest serves as essential living infrastructure to keep our city cool and resilient, and every New Yorker deserves equal access to its benefits. The Urban Forest Plan marks a turning point for how New York City grows, protects, and cares for its more than seven million trees, and NYC Parks is proud to help lead this effort alongside our partners and communities,” said NYC Parks Commissioner Tricia Shimamura. “Year over year we have planted a record number of trees, adding canopy where it is needed most, and investing in our forestry workforce to ensure our trees are protected. Now the Urban Forest Plan will help ensure a unified strategy for lessening the effects of climate change and ensuring that New Yorkers in every neighborhood can benefit from a healthier, greener, and more resilient city.”

"At City Parks Foundation, we are incredibly proud to have played a role in the development and release of New York City's first Urban Forest Plan," said Heather Lubov, Executive Director of City Parks Foundation. "Planting and preserving the canopy will, of course, be critical to the success of the city's efforts to cool and clean our communities, but we're thrilled that the newly released plan also puts stewardship front and center to ensure that both trees and communities thrive. We look forward to working with the city and the many dedicated individuals and grassroots and nonprofit partners to achieve the goals of the plan."

"We are thrilled that New York City's first Urban Forest Plan acknowledges the vital role of NYCHA campuses' tree canopy," said NYCHA Chief Executive Officer Lisa Bova-Hiatt. "Preserving and expanding the tree canopy not only provides physical comfort but also empowers residents through hands-on workforce opportunities. We are proud to work with our partners across the city toward greener NYCHA campuses and a more resilient New York City."

NYC Parks manages and cares for millions of street and park trees across all five boroughs, helping to grow and sustain the city’s urban forest.

Expanding Tree Canopy as an Environmental Justice Priority

An equitably distributed and ecologically diverse urban forest in New York City will cool neighborhoods, help manage stormwater, improve air quality, reduce greenhouse gas emissions, increase habitat for wildlife, and enhance the health of, and quality of life for, all New Yorkers. At the core of the UFP is the City’s commitment to addressing unequal distribution of tree canopy as a critical matter of racial and environmental justice. Environmental Justice communities have approximately 19% canopy cover, compared to 26% in non-Environmental Justice areas.

In the Bronx, for example, neighborhoods like Pelham Bay live under a dense, connected tree canopy that cools the air, filters pollution, and absorbs stormwater. Just a few miles away in Hunts Point, one of the hottest, most pollution-burdened neighborhoods in the city, the tree canopy covers only six percent of the neighborhood, among the lowest in the entire city and a fraction of the borough-wide canopy level of 27%.

Cross-Agency Coordination and Partnership

The Urban Forest Plan outlines strategies to close these gaps and expand canopy where it is needed most.

“Reaching 30 percent canopy will be a true whole-of-city effort, bringing together agencies across city government to work in lockstep with communities, nonprofits, and property owners, who will be the true stewards of these forests,” said Deputy Mayor for Operations Julia Kerson. “New York’s urban forest is living infrastructure, and like every system that keeps this city running, it deserves investment, care, and measurable goals. We look forward to delivering all three.”

To reach 30% canopy coverage by 2040, the UFP outlines measures to protect existing canopy, expand planting in streets and public spaces, promote tree planting on private property, and strengthen workforce and stewardship programs that engage New Yorkers in caring for the urban forest.

City agencies will coordinate implementation of the plan in partnership with community organizations, nonprofit and institutional partners, and private property owners. Progress toward the city’s 30% canopy goal will be tracked over time, with updates and continued public engagement helping guide the plan’s implementation and future iterations. The plan fulfills requirements under Local Law 148 of 2023, which mandated that the city develop and regularly update a long-term urban forest strategy informed by public engagement.

Paris is adding color, with boulevards, parks and multiple climate plans 

The City of Paris is famous for its boulevards, bistros and unmistakable character. But behind the historic façades, a nature revolution is taking place that increasingly attracting international attention. Streets, squares and parks are being redesigned and new green spaces are being created, gradually - but significantly - reintegrating nature into the urban landscape.

The capital is becoming greener – and for good reason. With its Climate Plan 2024–2030, the city has developed a master plan to make Paris more resilient, vibrant, and in tune with nature. But what does that mean in practice? It's not just about new parks; it's about an interconnected concept. Trees, schoolyards, measures to promote biodiversity, rainwater management and climate adaptation strategies will work together to prepare the city for future challenges. The goal is to create a city that is more resilient, healthier and equitable.

More nature despite the many paving stones

Paris is a densely populated city. Space is scarce. The city is exercising creativity to solve this problem:

• A mini urban forest in the middle of the city? Yes, on Place de Catalogne. Can you imagine a small forest in the middle of your city?
• School Streets: By 2026, 100 streets outside schools are set to become car-free and greener. Children can play safely, and the neighbourhood benefits from new recreational areas that serve as real meeting places in the middle of the city.
• A three-hectare green space is being created in the east of the city. It will offer recreation and leisure opportunities, as well as providing a habitat for plants and animals.

Paris was an early adopter of environmental protection. Pesticides were banned in parks and gardens as early as the 1990s, long before this became a nationwide requirement. Since 2015, the ban has also applied to cemeteries. What has been the result? Foxes and other wild animals are returning. Who would have thought that you could encounter wild animals in the middle of Paris?

Of course, more greenery also brings challenges. Trees need water, meadows need maintenance, and people must accept spontaneous vegetation. Not everyone immediately realises that unmown meadows and wildflowers are beneficial for the city and its residents. Fostering nature in a city is thus not only a planning challenge, it is an acceptance challenge.

People are getting involved – and that's crucial!

Participation plays a central role in Paris. In addition to experts and the city administration, NGOs, scientists and citizens were also involved in the Biodiversity Strategy 2030. Online consultations, public discussions and workshops ensured that as many voices as possible were heard. But what does this look like in everyday life?

Through the 'Embellir votre quartier' initiative, residents can actively participate in deciding which streets or neighbourhoods should be greened next. They can contribute their own ideas. Which tree species should be planted? Which places would be suitable for green retreats? This commitment is particularly evident in the School Streets initiative. Parents, teachers and children collaborate to design car-free zones outside schools. They also take over the maintenance later.

The initiative has a positive impact that goes beyond mere renaturing: it fosters a sense of responsibility, strengthens social bonds and creates a stronger sense of community. Those who get involved can see how urban planning can directly change their neighbourhood. And let's be honest – who wouldn't want to see their ideas suddenly brought to life in the heart of the city?

Paris as a laboratory for the city of the future

Paris is focusing on more than just individual parks and street trees. Instead, the city aims to become a laboratory for urban sustainability, striving to be dense, vibrant and socially just, as well as green and climate-resilient. To achieve this, it is relying on several interlinked comprehensive plans:

• The Bioclimatic Urban Master Plan: This plan sets out rules for increasing greenery in public and private spaces.
• The Biodiversity Strategy 2030 protects species and habitats, and includes specific actions for flora and fauna.
• The Tree Plan 2021–2026 involves planting 170,000 new trees on streets, in squares and forests, and along ring roads. These measures will improve the urban climate and create habitats for animals.
• The Paris Rain Plan aims to implement smart rainwater management to increase the city's resilience to climate change and protect it from flooding.
• Resilience Strategy: The city is to be made crisis-proof against heatwaves, flooding and social inequalities.

What Paris is currently building is therefore more than just an environmental programme. It is a laboratory for the city of the future: dense, vibrant and socially just, as well as green and climate-resilient. Once the plans have been implemented by 2030, Paris will not only be known for its culture and history, but also for a new kind of urban life in which trees, boulevards, parks, squares and people coexist with nature as a matter of course.

New Report: Paris Tomorrow

Paris was the birthplace of the 2015 Paris Agreement, which laid the foundations for a global commitment to climate protection. Since then, the City of Paris has prioritised the fight against climate change. By transforming public spaces to reduce motorised traffic, carrying out a large-scale renovation of buildings and committing to an ambitious energy transition to promote renewable energies and move away from fossil fuels, Paris has reduced greenhouse gas emissions by 26%. Paris has published a retrospective report, “Paris of Tomorrow” (“Paris Demain”), which reflects on sustainability actions implemented in 2024 - a landmark year for the ecological transition in Paris.

The new edition of Paris Tomorrow aims to monitor and analyze ecological and social transition in the city. Structured around 30 strategic indicators, it highlights the progress achieved so far.

For example:

• One-third reduction in CO₂ emissions since 2004 (start of GHG monitoring)
• From 35 to 45% decrease concerning the main air pollutants over the past 10 years
• 1,500 km of cycling routes developed across the city
• 1,500 cooling islands accessible to residents by 2025
• More than 130,000 trees planted since 2020
• 45% organic products served in municipal collective catering in 2024

The report also showcases concrete actions implemented in Paris in 2024, with a special focus on the Olympic Games.

Together with an online open data platform providing an update on the main indicators (in French), these two tools are designed to support decision-making, enhance transparency, and foster collective action toward carbon neutrality and resilience in Paris.

Paris shows how citizen-driven greening can make cities cooler and fairer

As European cities prepare Urban Nature Plans, one insight from ICLEI Member Paris (France) stands out: urban greening only succeeds when residents help shape it.

Over the past decade, Paris has expanded tree planting, opened green and blue corridors – connecting parks, waterways and former railway lines, allowing flora and fauna to move freely across the metropolis – and has restored water quality in the Seine. As a result, species diversity has grown tenfold since the 1970s – and Parisians can now swim in the river once again.

The city’s reimagining of its urban landscape was made possible through an ambitious biodiversity agenda, beginning with its 2011 Biodiversity Plan and continuing through today’s 2025 Biodiversity Strategy. Milestones include greening schoolyards, transforming 10% of city streets into pedestrian-friendly spaces and planting 150,000 trees by 2025.

But the city says the biggest gains come from working directly with communities, especially in areas most affected by heat and pollution. Through participatory budgeting, social housing safeguards and community-led design, Paris ensures greening efforts enhance – rather than displace – local communities.

UNP+ supports this shift by helping cities develop Urban Nature Plans that combine data, equity and public participation. Paris’s experience shows how mapping heat risks, identifying biodiversity gaps and involving citizens early can guide smarter investment.

The city’s advice for others is simple: start with a shared vision, engage people from the beginning and treat nature as a common good. Urban nature plans work best when cities and citizens act together.

Reclaiming the City: How Paris Is Transforming Public Space Through Pedestrianization and Greening

By Create Streets

Cities around the world are facing a common challenge: how to adapt dense, historically car-oriented urban environments, to the social and environmental issues of the 21st century. Local governments need to rethink the role of streets and squares as common public spaces.

Under its recent urban policies and a strategy begun with Anne Hildago’s first term as Mayor of Paris a decade ago, Paris has pioneered a people-first approach that integrates pedestrianization, greening, and community empowerment. The Parisian method is not simply about repaving streets or planting trees for their aesthetic value, it is a structural shift in how cities function, how residents move, and how communities interact. It reflects a broader ambition: to create healthier, more resilient, and more inclusive urban environments.

From Car-Centered Streets to People-Centered Spaces

Like most major cities, Paris was designed for the car in the 20th century. Wide boulevards and busy intersections prioritized motorway flow over public space, limited to narrow sidewalks, pinched between buildings and parking lanes. Yet over the past decade, Paris has undertaken one of the most ambitious programmes in Europe to reverse that trend.

Since 2014, Paris has restructured mobility around people rather than vehicles, through a network of pedestrian zones, green spaces and “calmed” streets, designed for people in everyday neighborhoods.

In Paris, street space, once used for parking or driving is now reimagined for multiple uses: walking, play, and social life. This shift is guided by the principle that reclaiming streets fosters not only mobility, but also community. Pedestrianization is at the heart of this shift. As traffic decreases and green corridors expand, Paris shows that urban vitality and environmental sustainability can reinforce each other.

By limiting or removing through-traffic in certain areas, cities significantly lower local air pollution, and create safer and more pleasant environments for walking, shopping, gathering, and cultural activities. It also stimulates local economic activity: businesses in pedestrian-friendly districts often benefit from increased foot traffic and longer visitor dwell time.

Beautify Your Neighborhood: Local Change, Citywide Impact

At the heart of the Parisian shift lies “Embellir votre quartier” (“Beautify Your Neighborhood”), a participatory program inviting residents to co-design their own streets. Operating in 2 to 7 sub-districts in each arrondissement (approximately 1 km²), the initiative empowers citizens to propose and prioritize projects such as wider pavements, new trees, pedestrianized squares and bike lanes.

This hyperlocal approach turns planning into a democratic process. Instead of imposing a uniform citywide template, Parisian officials work with local communities to respond to specific environmental, mobility, and social needs, sharing budgetary issues transparently. Each project, while modest in scale, becomes a piece of a broader metropolitan puzzle connecting active travel routes and green networks.

For example, a previously congested street in the 13th arrondissement might now feature school play areas, greening and bike parking spots, chosen through workshops with residents.

Transforming public space inevitably raises concerns. Shop owners may fear reduced accessibility, residents may worry about traffic displacement, and drivers may perceive restrictions as constraints. Transparent communication about objectives, timelines and budget, and participatory processes facilitate acceptance and result in a tangible sense of ownership: citizens not only use public space but help shape it. This participatory philosophy has become one of the city’s most effective tools for civic engagement and ecological renewal.

The Tree Strategy: Greening as Infrastructure

The Paris Tree Strategy has made possible the planting of 150,000 trees and the greening of 370 streets in six years. Furthermore the strategy committed to diversifying species and layouts to maximize nature’s ecological benefits. It embodies the transformation of Paris from a city with gardens to a “garden city” (“ville-jardin”).

This “garden city” vision complements the pedestrian’s everyday journeys across a city which sorely lacks green spaces and has been demonstrated to be the deadliest in Europe during heatwaves. Every new project – from redesigned avenues to new schoolyards – integrates shade and biodiversity corridors.

Tree-planting efforts are deliberately concentrated in working-class districts and social housing areas, neighborhoods where green space and air quality have historically lagged, particularly in the densely populated north and east of the city.

Paris reframes greenery as essential infrastructure, vital for resilience and public health: high-quality public green areas are critical for well-being and social cohesion.

Oasis Schoolyards and School Streets: Learning and Living in a Shared Urban Space

Greening initiatives also create opportunities for rethinking the design of school environments. More than 200 schoolyards have been redesigned as green spaces, some of them serving both students during the day and residents outside school hours. This dual function maximizes land use in dense districts and strengthens community ties.

Another innovative dimension of Paris’s transformation is found in its approach to School Streets (“Rues aux écoles”). Over 300 school streets have been redesigned as low-traffic or car-free areas where children can arrive safely on foot or by bike, away from congestion and emissions, and when it’s possible, alongside green infrastructure.

More than a child-safety project, School Streets visibly embody the “garden city”. They teach future generations that urban mobility and sustainability are compatible and that the quality of the urban environment matters to daily life.

They also embody a political method that reflects how Anne Hidalgo has brought about change throughout her decade as Mayor of Paris: Set radical and high ambition goals: here with School Streets, the pedestrianization of every street in front of a school.

 
Test the design: from the very first School Street and to this day, the Paris officials and political leaders observed what was not working and what was supported by residents and were not afraid to adjust
Keep repeating popular, local interventions in order to gradually transform the whole city: as the trials progressed, Parisians responded enthusiastically to some of these street transformations and began asking for those changes on their own streets. This allowed the City of Paris to identify the measures that both advanced its objectives and won public support, creating the conditions to roll them out at scale and deliver ambitious programmes (such as the transformation of 300 school streets.)

From Local Actions to Structural Change

Over time, these individual interventions accumulate into a structural transformation.

Results have been striking: as cycling infrastructure has expanded traffic volumes have declined on certain corridors and air pollution has decreased significantly, green spaces have multiplied and the Canopy Index has increased with them (from 21% in 2018 to 25% in 2025). A new urban ecosystem is taking shape.

Streets that once felt dominated by vehicles have become lively social spaces. Neighborhoods have gained an identity and vibrancy through redesigned plazas and tree-lined avenues that people then make their own and want to see multiplied.

Conclusion: The Parisian Way of Reclaiming the City

Bringing together bottom-up innovation and top-down strategy, Paris is bringing about a radical transformation of public space as well as redefining the social contract of the city. By empowering citizens to beautify their neighborhoods, investing in a tree planting strategy, and creating safer and greener school environments, Paris illustrates how 21st century cities can reconcile density with livability.

Political commitment in Paris proves that reclaiming streets for people and nature can produce not only cleaner air and quieter roads but also stronger, more connected communities.

The decisive victory of Emmanuel Grégoire in the 2026 mayoral election of the last few days signals continuity for the city’s urban agenda as the new mayor is set to embrace the legacy of Anne Hidalgo’s policies. He is set to continue the ongoing transformation of public spaces and mobility around Paris. This will not only persist but deepen: the pedestrianization of a further 1000 streets, the transformation of 10 avenues into parks, the extension of the park on the Banks of the Seine, with climate adaptation remaining a central priority. In this context, Paris is poised to further integrate environmental resilience into everyday urban life, accelerating its transition toward arguably the most climate-ready city in Europe.

The process begins small: one tree planted, one sidewalk reimagined, one street redesigned. Yet these local interventions accumulate into a profound structural change. In doing so, Paris is sending out a powerful signal about collective priorities: health over speed, quality of life over traffic throughput and community over congestion.

PROJETO DE REVITALIZAÇÃO DA ORLA DO CENTRO DE NITERÓI CONQUISTA PREMIAÇÃO NACIONAL DO IAB 2025

 

Projeto de Revitalização da Orla do Centro de Niterói, vencedor da etapa nacional da Premiação IAB 2025. Instagram IAB-Brasil.

Foi com muita alegria que celebramos mais uma premiação conferida à gestão, às políticas públicas, projetos urbanos, ambientais, de saneamento e de mobilidade da Prefeitura de Niterói. Desta vez, foi a prestigiosa Premiação Nacional IAB 2025, que reconheceu a qualidade e a relevância do Projeto de Revitalização da Orla do Centro de Niterói. A premiação foi na categoria “Urbanismo, arquitetura da paisagem, planejamento e cidades”. O proponente do projeto ao Prêmio foi a Secretaria Municipal de Mobilidade e Infraestrutura Urbana, por iniciativa do secretário Renato Barandier e do subsecretário Fabrício Arriaga.

O projeto foi desenvolvido, em 2021, na minha gestão como prefeito de Niterói e a obra foi entregue em dezembro de 2024. Estabeleci a Revitalização da Orla do Centro como uma das metas da Secretaria Municipal de Urbanismo e Mobilidade, que tinha então o arquiteto e urbanista Renato Barandier no comando e uma competente equipe a apoiá-lo. O projeto foi desenvolvido de acordo com o conceito de "Ruas Completas", implantado principalmente na Avenida Visconde do Rio Branco. A obra requalificou 2,5 km de orla e 500 mil m² de área reurbanizada. Dentre os diversos benefícios, o projeto entregou para Niterói as seguintes melhorias:

• Reurbanização da Avenida Visconde do Rio Branco, que ganhou solução para os ônibus, com pontos de ônibus confortáveis e localizados no canteiro central da via.
• Nova ciclovia ao longo da orla
• Calçadas acessíveis 
• Nova iluminação LED
• Novo Terminal de Ônibus para a Zona Sul.
• Nova Praça Arariboia: a implantação de uma explanada que valorizou a vista da Baia de Guanabara na Praça Arariboia, que antes estava obstruído por construções e um inadequado estacionamento, ao lado da estação hidroviária, que persistia naquele local há décadas.
• Duplicação do Bicicletário Arariboia.
• Conexão da Praça Arariboia ao Parque Esportivo da Concha Acústica, à Arena Niterói (fizemos o projeto e fizemos grande parte da obra, que está agora prestes a inaugurar), o Complexo de Atletismo da UFF, a Cantareira, a "Praça da Bicicleta" (onde localiza-se o Castelinho do Gragoatá, prédio tombado e que foi restaurado pela Prefeitura e que hoje é a sede da Coordenadoria do Niterói de Bicicleta) e o Forte do Gragoatá. 
• O projeto retirou outros estacionamentos que existiam no PEUC do Aterrado Norte (entre a Av. Visconde do Rio Branco e o Caminho Niemeyer), retirando um fluxo de cerca de 1.400 carros que se dirigiam ao Centro todas as manhãs e voltavam aos seus lugares de origem no final da tarde.
• Ampliação de 47% das áreas verdes (de 14.735 m² para 21.593 m²) e o plantio de 357 árvores melhoraram o microclima e a drenagem urbana, enquanto a ampliação de calçadas e travessias seguras promoveu conforto térmico e segurança viária.
• Poluição visual: retirada dos fios de telefonia aérea.

Não é a primeira vez que a Prefeitura é premiada pelos projetos urbanísticos da cidade. Conheça outros prêmios já conquistados aqui.

Parabéns Niterói, parabéns aos planejadores do desenvolvimento da Cidade de Niterói.

Projeto de Revitalização da Orla do Centro de Niterói

Veja, a seguir, as informações 

Por quase cinco décadas, o Centro de Niterói viveu um processo de esvaziamento urbano após a perda da condição de capital do antigo Estado do Rio de Janeiro e a inauguração da Ponte Rio-Niterói. O avanço da urbanização rodoviarista e a conversão de imóveis e áreas vazias em estacionamentos corroeram o espaço público e interromperam a relação histórica entre a cidade e o mar.

O projeto Revitalização da Orla Centro propõe uma reconciliação física e simbólica entre cidade e baía, reconfigurando um território antes degradado em um ambiente de mobilidade sustentável, vida urbana e inclusão social. A operação combina infraestrutura, habitação, paisagem e cultura em um sistema contínuo de espaços públicos que devolve à cidade sua frente marítima e sua centralidade.

A transformação abrange 2,5 km de orla e 500 mil m² de área requalificada, conectando o Caminho Niemeyer, a Praça Arariboia e o Parque Esportivo Municipal em um grande parque linear costeiro. Essa rearticulação urbana restabelece a visada para a Baía de Guanabara e integra os principais terminais metropolitanos de transporte, incluindo o sistema de barcas e o Terminal João Goulart, por onde circulam mais de 300 mil pessoas diariamente. A nova Praça Arariboia, implantada onde havia imóveis abandonados e um estacionamento, tornou-se o principal portal da mobilidade da cidade — um espaço de encontro entre o mar, o transporte e a cidadania.

A Av. Visconde do Rio Branco, eixo central da intervenção, foi totalmente reurbanizada segundo o conceito de Ruas Completas, priorizando pedestres, ciclistas e transporte coletivo. O novo corredor de ônibus, o Terminal Sul ampliado e as estações de design transparente materializam a integração entre transporte e paisagem. A restrição de 1.400 vagas de estacionamentos privados e a redução de 26% dos espaços públicos destinados ao automóvel reverteram a lógica rodoviarista, permitindo destinar solo a modos ativos e à convivência urbana.

Do ponto de vista habitacional, o PEUC do Aterrado Norte redefine o papel dos vazios centrais, transformando-os em instrumentos de concretização do direito à cidade e da moradia digna. Mais de 68 mil m² de áreas antes ocupadas por estacionamentos passam a cumprir sua função social, com 4.250 moradias adequadas e acessíveis licenciadas e 3 mil em construção, inseridas no maior polo de oportunidades urbanas do Leste Metropolitano. O conjunto segue os princípios de Desenvolvimento Orientado ao Transporte (TOD), aproximando moradia, trabalho e serviços, e induzindo a transição de um modelo disperso e dependente do automóvel para uma cidade compacta, acessível e de baixas emissões.

Os ganhos ambientais são expressivos: a ampliação de 47% das áreas verdes — de 14.735 m² para 21.593 m² — e o plantio de 357 árvores melhoraram o microclima e a drenagem urbana, enquanto a ampliação de calçadas e travessias seguras promoveu conforto térmico e segurança viária. A iluminação de alta eficiência e o mobiliário permeável visualmente reforçam a sensação de transparência e pertencimento, estimulando o uso noturno e contínuo dos espaços públicos.

Mais do que uma requalificação, a intervenção estabelece um novo paradigma de planejamento urbano para a Região Metropolitana do Rio de Janeiro, articulando transporte, habitação e sustentabilidade sob um mesmo desenho urbano.

Alinhado ao Plano Estratégico Niterói 2033, ao Plano Diretor e ao Plano de Mobilidade Urbana Sustentável, o projeto consolida uma mudança estrutural nas políticas urbanas de Niterói, redefinindo os padrões de deslocamento e moradia adequada de forma duradoura e coerente com a visão de futuro da cidade, garantindo benefícios permanentes para as gerações presentes e futuras.

Suas transformações pavimentam o caminho para uma cidade mais equitativa, resiliente e sustentável, onde as próximas gerações herdarão não apenas uma nova paisagem, mas um novo modo de viver, se deslocar e habitar — uma cidade que volta a se orientar pelas pessoas, e não pelos automóveis.

ICLEI: A reforma da ONU e a salvação do multilateralismo

Faltam apenas quatro anos para o final do prazo da Agenda 2030, instituída pela ONU, em 2015, com a assinatura de 193 países que compartilhavam muita esperança em promover a transição global para a sustentabilidade. O fim do prazo chega diante de uma das maiores crises já vividas pela ONU, que se vê diante dos ataques retóricos e pela retirada de apoio financeiro por parte do atual governo dos EUA e pela cobrança crescente de muitos dos seus membros por uma reforma institucional que reforce a sua democracia interna e capacidade de mediação de conflitos e sua liderança mundial. Na verdade, trata-se de uma crise do multilateralismo, que reflete na dificuldade de avanços da agenda global e na paz mundial, com sanções econômicas, agressões armadas, guerras unilaterais, com sérias consequências humanitárias e econômicas.

É nesse contexto, que o texto abaixo, assinado por Yunus Arikan, diretor de Advocacy do ICLEI - Governos Locais pela Sustentabilidade, analisa o momento de crise, mas também as iniciativas reformistas em curso e as perspectivas para uma nova ONU e para uma governança mais multinível e com uma participação mais ativa das instâncias subnacionais e, portanto, das cidades. 

O ICLEI  foi fundado em setembro de 1990, durante o Congresso Mundial de Governos Locais por um Futuro Sustentável na sede da ONU em Nova York. Atualmente, a sua sede está em Bonn, na Alemanha, reunindo mais de 2.500 cidades e governos regionais, em mais de 125 países, abrangendo todos os continentes. O ICLEI possui mais de 25 escritórios pelo mundo. Para mais informações, acesse www.iclei.org  

Como ressalta o nosso amigo Yunus, "o que falta não é ambição, mas alinhamento". Ou seja, é preciso avançar em direção a consensos que permitam os necessários acordos em torno de uma nova ONU.

UN beyond 80: An opportunity to position multilevel collaboration and urbanization to save multilateralism and sustainability

By Yunus Arikan

The United Nations marked its 80th anniversary in 2025. Over time, numerous UN Secretaries-General have sought reforms of the UN system, but were unable to achieve more than incremental progress due to limited buy-in from Member States.

This year is different.

The question is no longer whether the system needs reform, but whether it can deliver significant enough reform in time. With just four years until the review of the 2030 Agenda, the negotiations on what comes next will shape not only the future of sustainability, but also the credibility of the multilateral system itself. In a world shaped by overlapping crises – armed conflict, climate, biodiversity, inequality, and technological disruption – the gap between global commitments and real-world delivery is becoming almost impossible to ignore.

But this is not due to a lack of ambition – it is due to a lack of alignment.

The UN80 Initiative – an ambitious, system-wide reform effort – as well as the reform of the United Nations Economic and Social Council (ECOSOC) and the High-Level Political Forum, the review of the New Urban Agenda and SDG 11, the push for stronger synergies across the Rio Conventions, and the transition toward new UN leadership are all unfolding at once. The challenge is whether they can be composed into a coherent system for action, or remain fragmented efforts in an increasingly complex global landscape.

UN-wide reforms process: A portfolio of notes waiting for a composer to turn into a symphony

The Secretary-General of the United Nations, António Guterres – who will leave the position in December 2026 –, launched the UN80 Initiative to make the UN system more agile, integrated, and fit for today’s overlapping crises. The process also built on the outcomes of the Summit of the Future in 2024.

The start of the process happened to coincide with the beginning of the second Trump Administration in early 2025. The plan for the UN80 Initiative included budgetary implications amongst others, and it gradually transformed into a three-track process, focusing on administrative changes, options for redesigning existing institutions and opening the space for a more holistic system-wide approach.

The process reached a new momentum with the historic resolution of the UN General Assembly in March 2026, which introduced a strong support from UN Member States to the effort of the UN Secretary-General and extended the process until April 2027.

The ongoing reviews of the UN Economic and Social Council (ECOSOC) and the UN High-level Political Forum on Sustainable Development (HLPF) point in that same direction but through slightly different mandates and processes. While ECOSOC is the main UN body since 1945 covering all issues related to development, HLPF was created in 2015 to lead the 2030 Agenda for Sustainable Development. It merged the Commission for Sustainable Development under Agenda 21 – led by the environmental community since 1992 – and the Millenium Development Goals – dominated by economic and social actors since 2000. Joint review of ECOSOC and HLPF is especially important as the global community has to decide on the modalities for sustainable development beyond 2030, which is the target year for Sustainable Development Goals.

This July will herald the review of SDG 11 on Sustainable Cities and Communities by the HLPF and the midterm review of the New Urban Agenda by the UN General Assembly – two particularly important moments for the urban community. Until the inclusion of a dedicated goal for cities among 17 Sustainable Development Goals in 2015, urbanization was not considered part of sustainable development by the national governments and the UN system under Agenda 21.

Similarly, the HABITAT II community evolving since 1996 did not relate itself to sustainability until the New Urban Agenda in 2016. It would be desirable that with these two separate, consecutive and parallel reviews in July, a more systematic approach to converge urbanization and sustainable development can be established as one of the concrete inputs in the UN reforms package.

The UN reforms agenda is an opportunity for the environment community as well. For decades, global environmental governance was scattered around the Conference of Parties (COPs) of numerous multilateral environmental agreements, in particular of the three Rio Conventions on climate (UNFCCC), biodiversity/nature (CBD) and desertification/land (UNCCD), the UN Environment Assembly and the overall sustainable development community under the HLPF.

The Work Package 27 on Environment under UN80 Initiative to be led by UNEP and the UNFCCC could conclude this long overdue synergy process, building on ongoing efforts such as the CBD’s Bern Process, the UNCCD’s efforts and the Riyadh Action Agenda, as well as UNFCCC´s Action Agenda and COP30 Global Implementation Accelerator and reach to renewed modalities that are embedded into the overall UN reforms package.

Progress and, more importantly, the implementation and follow-up from 2026 onward of all these processes, will be shaped by the selection of the next UN Secretary-General, expected to take office in January 2027. Efforts are evolving from a diversity of Member States, the Presidency of the UN General Assembly, the UN SG Office and civil society that ensure transparency and accountability in the selection process which heavily depends on the veto power of the five Permanent Members of the UN Security Council, as well as high expectations for a female leader to take this helm for the first time in the history of the United Nations.

Non-UN processes: For good or for worse

If the formal multilateral system is under pressure, it is no surprise that alternative processes are emerging around it.

Some examples are positive – such as the The Fossil Fuel Non-Proliferation Treaty Initiative and the upcoming First Conference on the Transition Away from Fossil Fuels – a coalition of willing nations coming together outside of the climate negotiations process to drive forward the transition, which was a part of the outcomes of COP28.

But other examples seek to undermine the UN. The Board of Peace was organized outside the UN system and endorsed only in limited terms by the UN Security Council to coordinate reconstruction efforts in Gaza, and is an example of exclusive processes, which has yet to prove its effectiveness, taking into account consequences of escalation of military conflicts in the Gulf came after the launch of the initiative in early 2026.

At the same time, initiatives such as the Article 109 Coalition move in a slightly different style and direction. Rather than bypassing the UN system, they call for its review, operate on the provisions of its Charter, and update reflecting on the changing realities of the world. They argue that the current institutional architecture can no longer absorb the pressures placed upon it.

Seizing the time for multilevel collaboration and urbanization

This is precisely where local and regional governments matter, not as symbolic participants, but as institutional connectors.

Since 2012, the Global Taskforce of Local and Regional Governments, where ICLEI is a founding member and leads actively as its focal point to the Rio Conventions related processes, has shown what coordinated self-organization can achieve. It has unified a constituency, created common advocacy positions, and enabled more structured engagement across UN processes. The good practice in engaging with the UN Secretary-General’s Advisory Group on Local and Regional Governments built on that momentum and produced a strategy for more permanent and structured engagement of local and regional governments in intergovernmental processes and UN political bodies, which is actively presented at the ECOSOC/HLPF review process.

Another practical entry point into the UN system is the Forum of Mayors under the UN Economic Commission for Europe, format and impact of which have significantly evolved since its inception in 2020. Innovative practices like Forum of Mayor and proactive proposals of Global Task Force for constituency-based engagements should be seen as complementary efforts that can be discussed with Members States and partners within the UN system partners to ensure multilevel collaboration is appropriately reflected into the UN reforms packages.

The Local Governments and Municipal Authorities (LGMA) Constituency to the UNFCCC has been one of the good practices in constituency-based engagement in the UN system and shape the evolution of global climate governance by demonstrating that multilevel collaboration and urbanization as two-sides of the same coin to advance climate emergency action. Its COP30 Position – endorsed by more than 50 networks of local and regional governments from around the world – already made clear the relevance and importance of this, with a call to connect the COP30 outcomes to the UN80 reforms, for a new era for multilevel cooperation in the global climate and sustainability agenda. The LGMA has also wholeheartedly supported the Coalition for High Ambition Multilevel Partnership (CHAMP) launched at COP28 in Dubai in 2023 and since then, actively supported its implementation as well as advancing its governance and implementation. The CHAMP experience – where national governments commit to collaborate with their local and other subnational governments in design and implementation of national plans – can be considered as a good practice in evolving the UN system towards enhanced multilevel collaboration.

As part of UN75 consultations in 2020, ICLEI released a blueprint with four concrete proposals for UN reforms to enhance collaboration with local and regional governments and advanced it further in 2022. In 2025, ICLEI’s first Annual Review of Local and Subnational Action on the Rio Conventions confirmed how urgent this is. Climate, biodiversity, and land are converging. Governance is becoming more complex. Innovation is increasingly happening below and beyond formal structures. And local and regional governments are where this convergence is already being managed in practice, through land use, infrastructure, food systems, ecosystems, risk management, and public services.

Como Paris escolheu o caminho da adaptação climática?

Paris tem o mais ambicioso programa de adaptação climática no mundo. Saiba como a iniciativa está sendo implementada. 

Paris tem o mais arrojados e interessante exemplo de transformação de uma cidade para a resiliência climática. A cidade decidiu adotar uma estratégia de adaptação às mudanças climáticas, tendo o foco principal no enfrentamento das ondas de calor, trocando o asfalto pelo verde e enfrentando os engarrafamentos para reduzir a poluição.

Guerra ao automóvel 

Mediante consultas públicas, a Prefeitura vem aprovando seus planos climáticos desde 2007. O mais recente foi aprovado em 2025, através de um plebiscito que referendou a ampliação da política climática. A decisão foi retirar os automóveis de 500 ruas, além das 300 que a cidade já vinha fazendo desde 2020. A prioridade é implantar as ruas "car-free" nas proximidades das escolas. Os parisienses também decidiram abolir 10% das vagas para carros e triplicaram a taxa de estacionamento nas vagas que sobraram nas regiões centrais e mais movimentadas.

Com as obras, as áreas verdes e ciclovias estão tomando a cidade. Para garantir a permeabilidade e facilitar a drenagem e para prevenir o excesso de calor urbano, nas ruas em que o tráfego foi retirado, a pavimentação das ruas é substituído por canteiros, praças e mais arborização. Cada rua custa €500 mil. A decisão foi referendada por 66% dos votantes no processo de consulta. Com a limitação da circulação dos carros, a poluição do ar já reduziu 40% na última década.

Claro que uma guinada dessas não acontece sem polêmicas e insatisfações. A maior resistência veio do 'Bairro 18', que apesar da reação de uma parcela dos moradores, teve 73% dos votos a favor, bem acima do resultado geral da votação (66%). 

O texto traz informações sobre o processo de transformação do maior programa de adaptação climática em curso no mundo, através de uma entrevista com Christophe Najdovski, vice-prefeito e responsável pelas áreas verdes, parques, biodiversidade e bem-estar animal. 

As mudanças só estão sendo possíveis graças à liderança inovadora da prefeita socialista Anne Hidalgo, que está fazendo uma mudança urbana histórica em Paris e inspirando o mundo.

Como diz o texto abaixo, "Paris mostra que é possível fazer".

There is ‘a will and a way’ to green Paris

28 April 2025

Eurocities speaks with Christophe Najdovski, Paris Deputy Mayor for public space greening, parks, biodiversity and animal welfare, about the city’s recent vote to close 500 streets to cars and reallocate them to pedestrians, cyclists and green space.

Parisians vote for a greener city

Parisians voted 66% in favour of creating 500 more car-free streets and removing 10% of the city’s current parking spaces. In consultation with local residents this spring, five to eight streets in each neighbourhood will be chosen for transformation with a dedicated budget of €500,000 per street.

The plan expands on a green push led by the city’s mayor, Anne Hidalgo. Since 2020, Paris has already seen 300 streets planted and cleared of cars primarily around schools.

“For decades, cities were redesigned to accommodate cars,” says Christophe Najdovski. “Cars have dominated public space, leaving little room for the most vulnerable road users like children and the elderly. Now, there is a strong public demand to share public space more equitably.”

Najdovski is committed to reimagining public space as more than a transit corridor. He is driven by a vision of public space as a place where citizens can thrive and connect. “Over the years, children have disappeared from the streets,” he notes. “They were pushed out by dangerous traffic. It raises an important question: what place do we, as a society and as decision makers, give to children in our cities?”

Cars have dominated public space... Now, there is a strong public demand to share public space more equitably.— Christophe Najdovski, Paris Deputy Mayor

With the average car growing in size, children are even more vulnerable, often invisible behind high bumpers. Paris is taking their safety seriously, particularly near schools. The city is systematically introducing school streets: car-free areas outside schools where roads are closed to vehicles to create safer, more welcoming environments for families.

“This is also about giving power back to citizens,” adds Najdovski. “Our vision is that streets are more than a way to get from point A to point B in the fastest way possible.” Instead, he sees the school run as an opportunity to foster stronger communities. “When we speak to parents, many say they’ve started walking their children to school not out of necessity but for the simple pleasure of it.”

Growing a ‘garden city’

As the impacts of climate change intensify, Najdovski underscores the urgent need to boost urban resilience and how nature-based solutions are central to this transformation.

“There is both a will and a need to build a more resilient city. We must adapt to the consequences of climate change, and we know that greening the city is one of the main responses to that need.”

Paris is putting this into practice by removing concrete to allow rainwater to replenish groundwater, creating green spaces that support biodiversity and filter air pollution, and tackling the urban heat island effect to keep neighbourhoods cooler during summer. Largely driven by the city’s shift away from car-centric planning, the city has seen a 40% reduction in air pollution over the past decade. Biodiversity is thriving too, with over 600 new species (among a total 3400 recorded) recently recorded in the city compared to a few years ago.

This vision is part of the city’s broader strategy for climate resilience, biodiversity and liveability. “We’re working towards a garden city,” says Najdovski—“a city where nature is present even in unexpected places. Not just confined to parks and gardens, but integrated throughout the streetscape.”

Citizens want to be more involved in the decisions that affect their neighbourhoods and quality of life.— Christophe Najdovski, Paris Deputy Mayor

Local decisions made by locals

While this is the most recent, it is far from the only referendum Paris has held on the future of public space. The strategy reflects Mayor Anne Hidalgo’s commitment to involving citizens in decisions that shape their daily lives.

“There is a real social demand for more participation,” says Najdovski. “Whatever people may say, these votes are not insignificant.”

Paris has already seen several high-profile examples of this participatory approach. In 2023, over 100,000 people voted in a referendum on the city’s shared e-scooter services. Nearly 90% voted against renewing the contracts with private operators, leading to the removal of 15,000 free-floating scooters from city streets.

More recently, another 80,000 residents voted in favour of tripling parking taxes on “heavy, bulky and polluting” vehicles, primarily SUVs. The measure passed with 54% support.

Understanding low voter turnout

The most recent referendum saw just 4% of the population (around 56,000 people) go to the polls. While media and online speculation offer various explanations, Najdovski has his own perspective.

“One reason could be that many people in favour assumed the outcome was certain,” he suggests. “There may have been a kind of silent consensus.”

He also points to the practical challenges of organising local votes: “There are always issues like capacity, timing, communication. Not everyone hears about the vote in time, and some people struggle to get to polling stations.” While electronic voting might improve accessibility, he notes that it presents its own set of complications.

Broader political dynamics also play a role. When there are global crises like wars, inflation, social unrest, local issues can tend to take a backseat in the minds of voters.

Still, he urges perspective on the criticism. “Some of the politicians challenging the low turnout were themselves elected with less than 10% of eligible voters. Yes, 4% is low, but we must recognise that turnout is often low in local elections too. That doesn’t mean citizens don’t care about these issues. It means we need to improve how we engage them.”

“Hear the resistance and adapt”

Although the referendum passed with a strong 66% majority, concerns have emerged particularly from tradespeople and local residents who feel the changes could complicate daily life. The loudest opposition has come from the 18th arrondissement, yet, as Najdovski points out, that very neighbourhood voted in favour at 73%, well above the city-wide average.

Much of the resistance has been voiced by business owners worried about the potential impact on footfall and trade. However, research consistently shows that most customers do not travel to these shops by car and that pedestrianisation typically boosts business.

“These voices are a minority,” says Najdovski, “but we still need to hear them. You must listen to the concerns, adapt the project where needed, but at the same time, you have to listen to the majority. And the majority has spoken clearly in favour.”

Paris shows what’s possible

The Paris of today looks dramatically different from twenty years ago. “Where there’s a will, there’s a way,” says Najdovski. “What’s been done in Paris can be done in any city. Ten years ago, Paris wasn’t bike-friendly. Now, it is. It wasn’t a green city. Now, it is.”

He stresses that reclaiming space from cars doesn’t have to be slow. When there is strong social demand and political will, transformation can happen quickly. “We were elected for this. It’s what we promised, and now we’re delivering. It’s that simple.”

What we’ve done here, other cities can do too. You can manage big transformations if you do it with the citizens, and if you have the political will.— Christophe Najdovski, Paris Deputy Mayor

Over the past two decades, Paris has cut traffic and air pollution by half. In newly pedestrianised streets near schools, air pollution dropped by 25%, according to a recent survey. “That means cleaner air, less noise, and a better quality of life,” says Najdovski. “And it’s good for local shops too.”

His message is clear: these changes aren’t unique to Paris. “What we’ve done here, other cities can do too. You can manage big transformations if you do it with the citizens, and if you have the political will.”

Governo do Brasil publica documentos do Plano Clima Adaptação

 

Medidas definem diretrizes, metas e ações para reduzir vulnerabilidades e ampliar a capacidade de adaptação do país aos impactos da mudança do clima

O Ministério do Meio Ambiente e Mudança do Clima (MMA) publicou, nesta sexta-feira (13/2), a Estratégia Nacional de Adaptação e seus 16 Planos Setoriais e Temáticos que integram o Plano Clima, consolidando as diretrizes e as estratégias de adaptação.

O Plano Clima é o guia de implementação da meta climática nacional sob o Acordo de Paris (a NDC, na sigla em inglês), pela qual o Brasil se comprometeu a reduzir entre 59% e 67% de suas emissões líquidas de gases de efeito estufa até 2035 em relação a 2005.

Acesse aqui os documentos do Plano Clima Adaptação

Os documentos estabelecem diretrizes, objetivos, metas e ações voltadas à redução de vulnerabilidades e ao fortalecimento da capacidade adaptativa do país, em articulação com diferentes setores e entes federativos. Também reconhecem que os efeitos da mudança do clima atingem de forma desigual a população brasileira, com maior impacto sobre grupos socialmente mais vulneráveis.

Com 84,5% do total de municípios brasileiros e 324,6 milhões de pessoas afetados por desastres na última década, a adaptação é orientada pelos princípios da justiça climática, da proteção dos direitos humanos, da inclusão social e da redução das desigualdades, buscando apresentar uma resposta abrangente e sensível às particularidades de cada comunidade, setor e região, observando a intersetorialidade do problema.

Coordenada pelos ministérios do Meio Ambiente e Mudança do Clima (MMA) e da Ciência, Tecnologia e Inovação (MCTI), a elaboração do Plano Clima Adaptação foi construída por meio de processo participativo e interinstitucional, no âmbito do Comitê Interministerial sobre Mudança do Clima (CIM), sob a presidência da Casa Civil da Presidência da República (CC/PR).

O processo contou com envolvimento de órgãos e entidades da administração pública federal, representantes de governos estaduais e municipais, comunidade científica, sociedade civil, setor produtivo e demais atores estratégicos.

Cerca de 6 mil pessoas e 700 instituições foram mobilizadas presencialmente. Além de consultas públicas, oficinas técnicas, reuniões setoriais e temáticas, webinários e plenárias nas cinco regiões do país, a participação social foi impulsionada pela Plataforma Brasil Participativo, garantindo transparência, pluralidade de contribuições e alinhamento às realidades territoriais do país. A plataforma registrou cerca de 300 mil acessos e, na fase de consulta pública, somou mais de 3.600 contribuições aos documentos.

O que o Plano Clima Adaptação estabelece

A partir de um diagnóstico sobre os principais impactos da mudança do clima para os próximos dez anos, a Estratégia Nacional de Adaptação (ENA) contextualiza a agenda climática no Brasil e no mundo, indicando as diretrizes, os objetivos e as metas nacionais a serem seguidos pelo Governo do Brasil, bem como por estados e municípios em seus planos de adaptação, conforme estabelecido no artigo 6º da Lei nº 14.904, de 27 de junho de 2024, fortalecendo a articulação entre os diferentes níveis de governo.

O documento apresenta conceitos técnicos e a base metodológica que orientaram sua construção e a dos Planos Setoriais e Temáticos, com ênfase na abordagem de risco climático e no ciclo iterativo da adaptação, além dos normativos, compromissos internacionais e marcos legais relevantes.

Os 16 Planos Setoriais e Temáticos de Adaptação abrangem áreas fundamentais para a proteção da população, dos territórios e das atividades econômicas:

• Agricultura e Pecuária
• Agricultura Familiar
• Biodiversidade
• Cidades
• Energia
• Igualdade Racial e Combate ao Racismo
• Indústria e Mineração
• Oceano e Zona Costeira
• Povos e Comunidades Tradicionais
• Povos Indígenas
• Recursos Hídricos
• Redução e Gestão de Riscos e de Desastres
• Saúde
• Segurança Alimentar e Nutricional
• Transportes
• Turismo

Além disso, o Plano está estruturado em:

• 13 diretrizes nacionais;
• 9 objetivos nacionais;
• 12 metas nacionais;
• 51 objetivos setoriais e temáticos;
• 312 metas setoriais e temáticas;
• 810 ações voltadas à redução dos impactos climáticos.

O Plano Clima Adaptação traz a meta de atendimento com obras de prevenção de riscos de desastres, a ampliação em 180 mil hectares da cobertura vegetal em áreas urbanas,100% da carteira de investimentos em infraestrutura contratada pelo Governo do Brasil considerando os riscos climáticos, redução em pelo menos 30% as interrupções operacionais causadas por eventos climáticos em infraestruturas federais de transportes e a redução para 7,5% o total de municípios com nível de segurança hídrica mínimo. De acordo com as metas estabelecidas, o Brasil pretende erradicar a insegurança alimentar e nutricional grave até 2035.

Justiça Climática

O Plano Clima Adaptação prioriza a adaptação centrada nas pessoas, focando na redução de vulnerabilidades e na erradicação de desigualdades que perpetuam a pobreza e agravam os riscos associados à mudança do clima. Para tanto, a busca pela adaptação transformativa é essencial, não apenas para responder à mudança climática, mas também para reconfigurar os atributos fundamentais dos sistemas naturais e humanos.

Considerando a diversidade do Brasil e a realidade desigual que permeia a sociedade, vê-se a justiça climática como eixo norteador desse Plano em todo o ciclo iterativo da adaptação, buscando a identificação de como os riscos climáticos afetam diferentes populações e territórios.

Esta abordagem envolve a integração de temas transversais, como igualdade de gênero, mobilidade humana, racismo ambiental, Adaptação baseada em Ecossistemas (AbE) e cobenefícios com a mitigação de gases do efeito estufa.

Reconhece também a necessidade do fortalecimento do Federalismo Climático como chave para a implementação multissetorial e multinível do Plano Clima, considerando o território como a base das demandas sociais e onde, de fato, as políticas públicas se materializam. Sendo assim, tem como meta nacional garantir que todos os estados e ao menos 35% dos municípios brasileiros tenham Planos de Adaptação até 2035.

Para orientar a implementação das ações de adaptação no âmbito federal, o Plano levou em conta as possibilidades reais de financiamento e os recursos oriundos do orçamento público e fundos especialmente constituídos, em consonância com o planejamento governamental do Plano Plurianual, já destinados aos ministérios responsáveis pela execução dessas políticas.

Para as ações que ainda não contam com fontes de financiamento, espera-se que o Plano de Adaptação se traduza numa carteira de projetos em potencial e venha a subsidiar outros instrumentos fiscais e orçamentários para assegurar a execução e o monitoramento de iniciativas que promovam a resiliência climática no país.

Super El Niño? Modelos climáticos apontam para possível evento extremo no Pacífico ainda em 2026

Fenômeno pode pressionar temperaturas globais a níveis recordes e provocar secas, chuvas intensas e mudanças em padrões climáticos ao redor do mundo.

Por Roberto Peixoto, g1

O planeta pode estar caminhando para um El Niño forte ou até "super" ainda em 2026.

É o que indicam os dados mais recentes divulgados pelo Centro Europeu de Previsões Meteorológicas de Médio Prazo (ECMWF, na sigla em inglês), que apontam 98% de chance de um El Niño moderado se formar até agosto, com 80% de probabilidade de um evento forte e 22% de chance de atingir a categoria "super".

🌊 ENTENDA: O El Niño é caracterizado pelo aquecimento maior ou igual a 0,5°C das águas do Oceano Pacífico. O fenômeno acontece com frequência a cada dois a sete anos.

No Brasil, quando ele está em atuação, o calor é reforçado no verão e o inverno é menos rigoroso. Isso ocorre porque ele dificulta o avanço de frentes frias no país, fazendo com que as quedas sejam mais sutis e mais breves.

Não há um consenso, contudo, entre meteorologistas e climatologistas para a definição exata de um Super El Niño.

De forma geral, o termo é usado quando o aquecimento das temperaturas do mar nessa região-chave do Pacífico supera 2°C acima da média, provocando uma resposta atmosférica de grande magnitude.

“Os modelos já indicam a possibilidade de um El Niño forte a partir de maio, ganhando força ao longo do inverno. Mas ainda é cedo para falar em um ‘super El Niño’; por enquanto, esse cenário precisa de mais confirmação”, explica o meteorologista César Soares, da Climatempo.

Esses eventos raros ocorrem, em média, uma vez a cada 10 a 15 anos.

Atualmente, o mundo ainda está sob influência de uma La Niña fraca — o fenômeno oposto, marcado por águas mais frias que o normal.

Os modelos indicam que essa fase deve enfraquecer nos próximos meses, com possível transição para El Niño após julho. Até lá, uma janela de neutralidade climática deve predominar.

Mas se as previsões se confirmarem, os impactos serão sentidos em escala global: maior frequência de ondas de calor, concentração de chuvas intensas em algumas regiões e secas severas em outras, além de mudanças nas trajetórias de ciclones tropicais.

No Atlântico, a temporada de furacões pode ser mais tranquila: os ventos intensos nas camadas médias e superiores da atmosfera durante El Niños criam condições menos favoráveis para a formação de tempestades tropicais.

O histórico dos eventos anteriores serve de alerta para regiões vulneráveis. Durante o Super El Niño de 2015-16, secas severas castigaram partes da África, da América Central, da Ásia e da Oceania. Países tropicais da América do Sul, África, Oriente Médio, Índia e Austrália tendem a registrar calor e umidade extremos nesses períodos.

Há também o risco para as temperaturas globais. Eventos intensos de El Niño quase sempre empurram o planeta para anos recordes de calor, pois o calor liberado pelo oceano se redistribui pela atmosfera com meses de defasagem — o que significa que os efeitos mais intensos podem ser sentidos ao longo de 2027.

Apesar dos sinais crescentes, a incerteza ainda é significativa. As previsões de El Niño tendem a ser menos precisas nesta época do ano, sob influência da chamada "barreira de previsão de primavera" no Hemisfério Norte, um período em que os modelos climáticos apresentam menor confiabilidade.

“Esse tipo de evento é mais raro e, por enquanto, os dados ainda não são suficientes para confirmar um cenário tão intenso”, afirma Soares.

A Administração Nacional Oceânica e Atmosférica dos Estados Unidos (NOAA) avalia que o espectro de possibilidades ainda vai de uma La Niña fraca a um El Niño forte, e deve divulgar uma atualização nos próximos dias.

Historicamente, as projeções se tornam mais confiáveis a partir de junho
