Have efforts to reduce methane emissions in the United States been successful?
The collective results of EPA’s voluntary methane partnership programs, which started in 1993 and 1994, have been substantial. As of 2005, these programs have contributed to reducing total U.S. methane emissions more than 11% below 1990 levels, in spite of significant economic growth over that time period. EPA expects that these programs will maintain emissions below 1990 levels in the future due to expanded industry participation and the continuing commitment of the participating companies, municipalities, and other organizations to identify and implement cost-effective technologies and practices.
