For governments, these include integrating mitigation and adaptation policies in tourism planning, considering tourism in national climate vulnerability assessments, promoting collaboration between national and local governments and the private sector to communicate the benefits of adapting to a low-carbon economy, considering poverty reduction as a tourism development goal, and combining REDD actions with small-scale, high-value nature-based tourism in forest communities to provide alternative sources of income. The OECD works closely with governments to help them to identify and implement least-cost policies to reduce GHG emissions in order to limit climate change, as well as to integrate adaptation to climate change into all relevant sectors and policy areas (OECD, 2007). As OECD countries are the major international donors, OECD has a critical role in tracking climate finance, and in examining how public finance can be scaled-up and best targeted to help leverage private financial flows.
