The World Bank has created the World Bank Carbon Finance Unit (CFU). The World Bank CFU uses money contributed by governments and companies in OECD countries to purchase project-based greenhouse gas emission reductions in developing countries and countries with economies in transition. The emission reductions are purchased through one of the CFU's carbon funds on behalf of the contributor, and within the framework of the Kyoto Protocol's Clean Development Mechanism (CDM) or Joint Implementation (JI). The World Bank is particularly supportive of Program of Activities (PoA) development.
