This document discusses tools for mainstreaming climate change adaptation into policymaking from a Finnish perspective. It outlines Finland's adaptation policy cycle, which includes national adaptation strategies (NAS) and sectoral adaptation programs evaluated through research programs. Key mechanisms for mainstreaming include the NAS, sectoral programs, European funding, and development of tools like climate projections and flood maps. Barriers to mainstreaming include lack of uptake by all sectors, poor recognition of cross-sector effects, and limited diffusion to the local level. The outlook discusses a proposed Climate Act and implementation of the updated 2014 NAS.
