American Petroleum Institute


The American Petroleum Institute (API) is the oil and gas industry’s largest trade association, claiming to represent over 650 corporate members engaged in oil production, extraction (including fracking), distribution, and other aspects of the industry. 

Based in Washington, API has offices in 27 state capitals and is a powerful lobby and major political spender, with numerous front groups to advance its political agenda. It also funds right-wing groups like the Koch-founded Americans for Prosperity (AFP) PAC and the American Legislative Exchange Council (ALEC).

On May 9, 2022, API’s Vice President for State Government Relations Rolf Hanson held a call on “the SEC Climate Rule proposal” with State Financial Officers Foundation (SFOF) members and former SEC Commissioner Paul Atkins, an email obtained by the Center for Media and Democracy details. Unsurprisingly, API has lobbied against all manner of environmentally sound policies, including fracking injunctions and methane-emitting fees. It is also one of the largest fossil fuel donors to the Republican Attorneys General Association (RAGA).
