Why Is Methane Important?
Methane, the primary component of natural gas, accounts for 16% of all greenhouse gas (GHG) emissions resulting from human activities. Because methane is both a powerful GHG and short-lived compared to carbon dioxide, achieving significant reductions would have a rapid and significant effect on atmospheric warming potential. EPA’s Methane Web site provides detailed information about methane’s role as a GHG; the sources of methane and current emission levels; projections of future methane emissions and the costs associated with reducing those emissions; and EPA’s voluntary programs to reduce methane emissions within the United States. The Methane to Markets Partnership is an international initiative that advances cost-effective, near-term methane recovery and use as a clean energy source. The Methane to Markets Partnership Web site contains the most comprehensive and up-to-date information on Partnership activities.
