The Environmental Integrity Project is a nonpartisan, nonprofit organization that advocates for more effective enforcement of environmental laws. The organization was founded by Eric Schaeffer, who directed the U.S. Environmental Protection Agency's Office of Regulatory Enforcement until 2002, when he resigned after publicly expressing his frustration with efforts of the Bush Administration to weaken enforcement of the Clean Air Act and other laws.

GHASP and the EIP work together on a number of projects. We've worked together to press for accurate reporting of pollution by polluters. We've advocated for rules that will help with enforcement of laws affecting activities at chemical plants and refineries that cause "upsets" or "emissions events." We've worked for rules to ensure that permits have actual, enforceable limits on pollution instead of general allowances for pollution that cannot be enforced with verifiable methods.
