Basic Information about Landfill Gas

U.S. Environmental Protection Agency

US EPA Landfill Methane Outreach Program (LMOP)

Urban Farm DB summary

According to US EPA's LMOP page, landfill gas is roughly 50% methane and 50% CO2, and methane is at least 28 times more effective than CO2 at trapping heat over 100 years. Municipal solid waste landfills are the third-largest source of human-related methane emissions in the US, accounting for about 14.4%. There are 542 operational LFG energy projects nationwide, about 63% generating electricity and about 20% producing renewable natural gas.
