The International Emissions Trading Association (IETA) is a non-profit business organisation created in June 1999 to establish a functional international framework for trading in greenhouse gas emission reductions.

Our membership includes leading international companies from across the carbon trading cycle. IETA members seek to develop an emissions trading regime that results in real and verifiable greenhouse gas emission reductions, while balancing economic efficiency with environmental integrity and social equity.

Our 2018 Priorities

As national contributions to the Paris Agreement are implemented, IETA
will advocate the power of emissions markets that price carbon
effectively and address climate change. We will --

Promote expansion of carbon markets around the world.
Improve the credibility and functionality of today’s carbon markets.
Promote effective linkages between carbon pricing systems over time.
Provide leadership and development opportunities for carbon offsetting.
Support effective models of private sector engagement in climate finance.
