Responding to regional demands, the World Bank’s climate change program has contributed to mainstream climate and disaster management concerns in public policy. The vast majority of LAC countries focus on both adaptation and mitigation. An increased awareness of climate change paved the way for key initiatives in Mexico, Brazil and Peru, among others, that cemented the region’s green leadership—despite accounting for only about 6 percent of total global greenhouse emissions from the power sector. Against the backdrop of the COP16 United Nations Climate Change Summit held in Cancun in November 2010, LAC led other regions in the search for a comprehensive approach to addressing mitigation and adaptation to climate change—an endeavor that can cost developing nations US$100 billion per year through 2050. Currently more than 170 “green” programs are active in the region with Bank support totaling more than US$5 billion.
