Climate change (CC) impacts on health outcomes, both direct and indirect, are sufficient to jeopardize achieving the World Bank Group’s visions and agendas in poverty reduction, population resilience, and health, nutrition and population (HNP). In the last 5 years, the number of voices calling for stronger international action on climate change and health has increased, as have the scale and depth of activities. But current global efforts in climate and health are inadequately integrated. As a result, actions to address climate change, including World Bank Group (WBG) investment and lending, are missing opportunities to simultaneously promote better health outcomes and more resilient populations and health sectors. Accordingly, with the financial support of the Nordic Development Fund (NDF), the World Bank Group set out to develop an approach and a 4-year action plan, outlined in this paper, to integrate health-related climate considerations into selected WBG sector plans and investments.
