Co-benefits rarely enter quantitative decision-support frameworks, often because the methodologies for their integration are lacking or not known. This review fills in this gap by providing comprehensive methodological guidance on the quantification of co-impacts and their integration into climate-related decision making based on the literature. The article first clarifies the confusion in the literature about related terms and makes a proposal for a more consistent terminological framework, then emphasizes the importance of working in a multiple-objective–multiple-impact framework.

Ecosystem-based adaptation (Eba) uses biodiversity and ecosystem services as part of a larger adaptation strategy to climate change. While the conservation and sustainable development community considers EbA to be a strong method of addressing climate change and its associated challenges, there is still a tendency for policy makers to implement traditional engineering solutions for adaptation, rather than investing in EbA.
