Stephen Kretzmann founded Oil Change International in 2005 in order to educate about the true impacts of fossil fuels, to conduct research, education, and organizing to hasten the transition to clean energy, and to strive for a Separation of Oil and State. He has worked on environmental and social issues around the global fossil fuel industry for the last twenty-five years. After eight years in Greenpeace where he was an early leader in climate campaigns, he became the environmental adviser to the late Ken Saro-Wiwa and the Movement for the Survival of the Ogoni People in Nigeria.  For the next ten years, before founding Oil Change International, he worked with communities, public and private financial institutions, corporations, and organizations around the world concerned with the environmental, social, and economic impacts of the fossil fuel industry. He has always connected support for these community-based efforts with systemic critiques of the industry for climate reasons. Mr. Kretzmann has testified before U.S. Congress, authored numerous articles and reports, and is a regular media commentator on issues of corporate accountability, climate change, the global fossil fuel industry, and environmental and human rights.
