Carbon Action

Modeling and measuring carbon storage of green spaces at different urban scales

CO-CARBON is a multidisciplinary research project aiming to quantify the carbon storage of green spaces at different urban scales using novel measurements and process-based models. A wide range of socio-ecological factors will be considered while evaluating the planning and management needs of carbon-smart green spaces.

Official name

Individuals, communities, and municipalities mitigating climate change by carbon smart green space (CO-CARBON)


2020–2023, possible continuation 2024–2026.

Carbon sequestration capacity of urban green spaces for use

Urban green infrastructure plays a key role in climate change mitigation and adaptation. Vegetation and soil store atmospheric carbon, modify local climate conditions, enhance stormwater cycling, and increase human well-being.

In CO-CARBON, atmospheric, soil and social scientists work together with landscape designers and urban planners. New solutions and knowledge for planning, implementation and maintenance of carbon smart urban green infrastructure are developed. This will be done in collaboration with project partners, citizens, businesses and city planners. The project aims to make carbon smart green spaces well-recognized as part of urban transition at different societal levels.
