Nature-based climate solutions are among the most effective and fastest ways to reduce greenhouse gases while delivering wide-ranging benefits for people and ecosystems.
These solutions—ranging from restoring wetlands and reforesting degraded lands to adopting regenerative farming and expanding urban green space—work by enhancing natural processes that capture carbon, reduce climate risks, and improve community resilience.
Why nature-based solutions matter
– Carbon sequestration: Healthy soils, forests, and wetlands naturally store carbon. Restoring degraded landscapes and changing land management practices increase that storage over time.
– Climate adaptation and risk reduction: Coastal marshes and mangroves buffer storm surges and erosion; urban trees lower temperatures and reduce heat-related health risks; wetlands and healthy soils improve water retention, cutting flood risk.
– Biodiversity and co-benefits: These approaches support wildlife, improve air and water quality, and create recreational and economic opportunities for local communities.
High-impact approaches
– Regenerative agriculture: Practices such as cover cropping, reduced tillage, diverse crop rotations, and agroforestry improve soil health and increase carbon retention. They also improve yields, reduce the need for synthetic inputs, and make farms more resilient to drought and heavy rainfall.
– Wetland and peatland protection: Peatlands and wetlands are disproportionately valuable carbon stores and natural water filters. Protecting existing peatlands and restoring drained ones prevents carbon release and restores ecosystem services.
– Forest restoration and improved forest management: Species-appropriate reforestation, avoided deforestation, and sustainable logging practices keep carbon in the ground while restoring habitats and supporting livelihoods.
– Coastal habitat restoration: Rebuilding oyster reefs, mangroves, and marshes reduces coastal erosion and storm surge impacts while sequestering carbon.
– Urban nature and green infrastructure: Tree canopy expansion, green roofs, permeable pavements, and rain gardens cool cities, reduce energy demand, and manage stormwater, delivering immediate local benefits.
Financing and scaling strategies
Financing mechanisms are critical to scaling nature-based solutions. Blended finance—combining public funds, private investment, and philanthropic capital—can de-risk projects and attract larger investors. Carbon markets that value high-integrity, nature-based credits are evolving, and performance-based payments for ecosystem services can reward land stewards for verified outcomes. Local governments can use zoning, incentives, and public procurement to accelerate adoption.
Principles for success
– Science-driven planning: Use local ecological data and climate projections to choose the right interventions for each landscape.
– Community engagement: Projects that involve local people, Indigenous communities, and land managers deliver better outcomes and equitable benefits.
– Long-term stewardship: Nature-based solutions require maintenance and monitoring; durable funding and legal protections ensure longevity.
– Transparency and verification: Robust monitoring protocols and third-party verification increase credibility in carbon and ecosystem service markets.
How individuals and organizations can act
– Support local restoration projects or volunteer for tree planting and wetland clean-ups.
– Choose food grown with regenerative practices and advocate for sustainable purchasing in institutions and businesses.
– Encourage city planners to prioritize green infrastructure and equitable access to parks and urban trees.
– Push for policies that protect critical ecosystems and incentivize nature-based solutions in climate planning.
Nature-based climate solutions are practical, effective, and deliver multiple benefits beyond carbon removal. When combined with deep emissions reductions and responsible land use planning, they form a crucial component of a resilient, low-carbon future.
