Landfill methane capture and destruction projects are an emissions-reduction project type within the waste & methane segment of the carbon market. They are designed to collect landfill gas and destroy or utilize methane that would otherwise escape. The carbon benefit comes from avoided methane emissions from uncontrolled landfill decay. Common project configurations include Landfill gas flaring; landfill gas utilization.

Methane management at landfills can be highly impactful, but gas generation models, collection efficiency, and timing all affect real outcomes. Many of these pathways focus on methane or other potent non-CO2 gases, so they can have strong near-term climate significance; at the same time, the integrity of baseline assumptions, destruction efficiency, and ongoing monitoring is especially important. For buyers and program designers, the most important diligence questions are: Is baseline capture accurately defined? Are collection efficiencies conservative? Are legal requirements already mandating control?
