Clean Development Mechanism
The Clean Energy Ministerial (CEM) is a global forum to promote policies and share best practices to accelerate the global transition to clean energy.  CEM initiatives help reduce emissions, improve energy security, provide energy access, and sustain economic growth.

The forum has included partnerships and collaboration between the private sector, public sector, non-governmental organizations, and others. The forum typically incorporated two interrelated features: 1) an annual high-level policy dialogue with energy ministers and other top global stakeholders; and 2) year-round policy-targeted technical initiatives and high-visibility campaigns. The CEM is currently the only regular meeting of energy ministers focused exclusively on clean energy.

Through the CEM, 23 countries and the European Commission collaborate on efforts to improve energy efficiency, enhance clean energy supply, and expand clean energy access. Members of the CEM as of 2016 are Australia, Brazil, Canada, China, Denmark, European Commission, Finland, France, Germany, India, Indonesia, Italy, Japan, Korea, Mexico, Norway, Russia, Saudi Arabia, South Africa, Spain, Sweden, United Arab Emirates, United Kingdom and United States of America.
