News Release - 1 June 2016

The Climate Accountability Institute, on the advice of counsel and in cooperation with our colleagues at Union of Concerned Scientists and other collaborating organizations and charitable foundations, has declined the request from the U.S. House of Representatives’s Committee on Science, Space, and Technology to provide all documents and communications relating to certain projects and publications conducted by the Institute, by the State of New York Office of the Attorney General, other State Attorneys General, and other NGOs and foundations working on corporate accountability for climate change.

The Institute was established by Richard Heede, Naomi Oreskes, and Greg Erwin as a non-profit research and educational organization.

The Climate Accountability Institute engages in research and education on anthropogenic climate change, dangerous interference with the climate system, and the contribution of fossil fuel producers' carbon production to atmospheric carbon dioxide content. This encompasses the science of climate change, the civil and human rights associated with a stable climate regime not threatened by climate-destabilizing emissions of greenhouse gases, and the risks, liabilities, and disclosure requirements regarding past and future emissions of greenhouse gases attributable to primary carbon producers.

Our vision is for a world protected from the social, economic, and environmental damages of climate change.

Our mission is to use climate accountability as a fulcrum for climate stewardship.

Our strategy is to leverage accountability by carbon producers into using their skills, capital, and resources to aid rather than oppose the transition to a low-carbon or zero-carbon energy future.

We are pleased to announce the publication of the Carbon Majors results. For more information please go here. For Publications go here.
