 At the United Nations Framework Convention on Climate Change conference in Copenhagen in December 2009, U.S. Secretary of Energy Steven Chu announced that he would host the first Clean Energy Ministerial to bring together ministers with responsibility for clean energy technologies from the world's major economies and ministers from a select number of smaller countries that are leading in various areas of clean energy.Members of the Clean Energy Ministerial (as of 2016) represent about 90% of global clean energy investment and 75% of the world's greenhouse gas emissions.Developing countries hold 50% of capacity for building out clean energy, but more than 70% of growth in clean energy investment since 2000 has been in OECD countries.
