The waste sector includes landfills and municipal wastewater systems. Methane (CH₄) emissions from these two sectors account for 12% of projected 2030 global non-CO₂ emissions, or approximately 1,568 million metric tons of carbon dioxide equivalent (MtCO₂e). Assuming full implementation of current technology, the global abatement potential for the waste sector is projected to be 807 MtCO₂e in 2030.
