On June 7, 2007, leaders at the 33rd G8 summit issued a non-binding communiqué announcing that the G8 nations would "aim to at least halve global CO2 emissions by 2050". The details enabling this to be achieved would be negotiated by environment ministers within the United Nations Framework Convention on Climate Change in a process that would also include the major emerging economies. Groups of countries would also be able to reach additional agreements on achieving the goal outside and in parallel with the United Nations process. The G8 also announced their desire to use the proceeds from the auction of emission rights and other financial tools to support climate protection projects in developing countries.
