UNEP's Climate Change Strategy is the result of a comprehensive process involving external experts and UNEP staff from across the organization. The strategy is built on the analysis of UNEP's political mandate, the existing portfolio of climate change activities and the areas of distinctiveness. The Climate Change Strategy provides the foundation for transforming the organization's engagement on climate change and for developing a results-oriented programme of work. UNEP will complement other processes and the activities of other institutions and will emphasize the substantial co-benefits of climate change actions and their contribution to environmental sustainability.
