Our membership is comprised of some of the world's top companies, from across the carbon trading cycle.






The International Emissions Trading Association (IETA) is a nonprofit business organization 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.

As of June 2013, IETA comprises more than 150 international companies from OECD and non-OECD countries. IETA has formed several partnerships including, among others, the World Bank, Eurelectric, the World Business Council for Sustainable Development (WBCSD) and the California Climate Action Registry, the Edison Electric Institute (EEI), the Electric Power Research Institute (EPRI), Carbon Market Institute (CMI) and the San Francisco Carbon Collaborative.

IETA currently has offices in Geneva (Switzerland), Brussels (Belgium), London (UK), Toronto (Canada), Melbourne (Australia) and US offices in Washington, DC and San Francisco, CA.





Membership in IETA (like membership of any trade association) is not a guarantee of any particular business status or a substitute for Know Your Customer or other checks.
