About Cities4Forests

A City-led Movement to Protect Forests


Cities4Forests is a coalition of more than 60 cities from around the world involving mayors’ offices and other city agencies, such as public water utilities and offices of sustainability. Cities4Forests encourages peer-to-peer learning and connects cities with technical support from institutions with expertise in cities, forests, climate crisis, water, communications, finance, policy and social equity. This helps cities recognize their interdependence with the world’s forests and use their political, economic and cultural power to protect and manage those forests for human well-being.

We help cities better conserve, manage and restore their inner forests, including city trees, urban parks, natural areas and other green infrastructure; nearby forests, such as watersheds; and faraway forests, especially tropical forests. We assist cities by inspiring political action and engagement, providing technical assistance, building capacity, and facilitating economic analysis, finance, and investment.

Building an Alliance Between Cities and Forests

Trees and forests are essential to cities and their residents, providing many benefits for climate, water, biodiversity and resident health and well-being.

Yet forests remain under threat, as the world lost roughly one soccer field of forest every six seconds in 2019. Deforestation and forest degradation account for approximately 11 % of carbon emissions — more than the entire global transportation sector. As a result, halting deforestation and helping forests recover naturally could provide up to 30% of the climate solution. If tropical deforestation was a country, it would rank third in carbon dioxide-equivalent emissions, only behind China and the United States. Deforestation and poor forest management can devastate local communities by increasing erosion, landslides, wildfires, flooding and loss of livelihoods.

At the same time, cities face unprecedented pressure to protect the health of their residents, provide access to outdoor green spaces and address social disparities. Cities are also facing rising costs from climate change, water scarcity, pollution, a global economic downturn and the prospect of tight municipal budgets. As cities seek to “build back better” from recent health and economic crises, they need to think beyond traditional concrete-and-steel infrastructure and embrace natural systems that can provide a range of co-benefits at a relatively low cost. So how can cities better support forests, both within and beyond their borders? Innovative plans, resident-engagement strategies and enhanced policies and procurement practices have enormous potential to support forest conservation and restoration. This potential exists in protecting and maintaining local forests, including parks and urban forests within their boundaries, as well as promoting “green infrastructure”; nearby forests that protect water supplies and would benefit from watershed management programs; and faraway forests that are vital for combating the climate crisis, decreasing the loss of biodiversity and supporting large-scale weather patterns. Regardless of where forests are, cities have a responsibility — and a lot to gain — to protect and restore them.

Inspire Political Action & Engagement:

We empower cities, their mayors and their residents to become advocates for trees, forests and green infrastructure in their cities and beyond. We increase awareness and understanding among city decision-makers and urban residents about the potential benefits of forests for their well-being. We use our platform to help align, aggregate and amplify the voices of cities in their advocacy for forests locally and globally.

Provide Technical Assistance & Capacity Building:

We offer technical support to improve city government plans, policies and forest management. We also assist cities with urban tree mapping, forest planning and monitoring. We collect and share best practices, establish peer exchanges and promote a network that allows a more efficient exchange of information. We support research and development efforts for promising technologies, including those for monitoring.

Facilitate Economic Analysis, Finance & Investment:

We seek to attract and scale financial investment in forests by increasing literacy of conservation finance approaches, enhancing bankability of projects and replicating and scaling novel financing approaches. We improve connections between cities, project developers and investors by building pipelines for investable opportunities. Through this, we move forests and other green infrastructure from a niche specialty to a major opportunity for investors.
