On the "climate" side of our issues, there are a lot of other organizations out there operating in the same space. This list is by no means comprehensive, but it is a good place to see many of the other groups (either for - or against) working in this arena. If we've missed someone or made an error, please feel free to let us know and we will update this page accordingly.

Groups Working on Climate

Global Initiatives
UN Framework Convention on Climate Change
Most inclusive and legitimate global treaty on climate policy in effect. Members meet at annual COP summits. Contains no binding limits on emissions and provides no enforcement mechanisms on emission reduction. The Framework provides the means with which to negotiate other treaties that could create binding measures on emissions and climate.

IMF
Provides research and support for carbon pricing. Lagarde supports carbon tax over cap-and-trade because it raises revenue and provides a predictable price of carbon.

World Bank
A couple of initiatives focusing on bringing together current carbon pricing members to collaborate on effective policy and to call on other entities to price carbon.

Carbon Pricing Leadership Coalition (Launched at COP21)
Goal: “Expand the use of effective carbon pricing policies that can maintain competitiveness, create jobs, encourage innovation, and deliver meaningful emissions reductions.”

Partners: Netherlands, Norway, Morocco, Alberta, Quebec, British Columbia, California, France, and other countries; more than 50 private sector companies, including energy companies; 17 NGO and nonprofit partners including the IMF, Ceres, and We Mean Business

Carbon Pricing Leadership Panel
Goal: “[Call] on their peers to follow their lead and put a price on carbon.”

Membership: World Bank Group, IMF, OECD, Germany, France, California, Chile, Ethiopia, CalPERS, Engie, and others

International Carbon Action Partnership
“Facilitates cooperation between countries, sub-national jurisdictions and supranational institutions that have established or are actively pursuing carbon markets through mandatory cap and trade systems.”

31 full members and 4 observers: EU, Switzerland, RGGI, WCI (California, Quebec, Manitoba, BC, etc.), Oregon, Washington, Arizona, Australia, New Zealand, Tokyo. Observers: Japan, Kazakhstan, Korea, Ukraine.

US Agencies
USAID
Global Climate Change and Development Strategy--Five year plan that focuses on:

“Support for climate-smart development reaches more than 50 countries around the world, with on average about $335 million per year from fiscal years 2010-2015.”

Adaptation: improving resiliency by identifying and addressing specific climate risks.
Mitigation: reducing emissions while achieving growth, which focuses on renewable energy and sustainable land practices).
Integration: putting climate knowledge into practice in all appropriate policy planning areas.

Export-Import Bank
In response to President Obama’s Climate Action Plan, the Ex-Im bank board agreed to stop financing most new coal plants abroad. In reauthorization negotiations, some in Congress have worked to prohibit this order.
