We are facing two global environmental crises, the loss of biodiversity and climate change. Both crises should be handled within the forthcoming decades. Actions implemented to mitigate one challenge should not worsen the other. The two crises are interlinked. Biodiversity, together with geophysical and climatic factors form and maintain ecosystems, which contribute to climate change mitigation by capturing CO2 and store carbon. But the current climate change worsen the negative impact of the main drivers causing biodiversity loss. This leads to further degradation of ecosystems, which in turn may weaken the functionality of ecosystems that reduce the ability of nature to capture and store carbon. The project identified eight cases related to nature-based solutions enacted in the Nordic countries and identifies synergies between biodiversity conservation and climate change mitigation.
