Despite growing political support for the use of nature-based solutions in climate change mitigation, a number of concerns have been raised. These include uncertainties about the scale of the contribution, especially given challenges with implementation and financing, doubts about whether the necessary safeguards will be put in place, and worries about the use of offsets by the private sector.
This report assesses the current state of knowledge on the size of the contribution that nature-based solutions can make and the types of action they will involve. It also discusses the importance of social and environmental safeguards, how nature-based solutions can be financed and the role of offsets. Most importantly, it considers the potential of nature-based solutions for mitigation to also contribute to climate adaptation and other pressing challenges.
