The Waste Methane Toolbox: Policy Solutions for a Low Methane Future

The waste sector, including solid waste and wastewater, accounts for approximately 20% of global anthropogenic methane emissions, or about 5.4 gigatons of carbon dioxide equivalents per year. To address this, the Clean Air Task Force introduces a 'Waste Sector Methane Mitigation Policy Matrix' designed to help policymakers navigate environmental policy taxonomies and build integrated solid waste management systems. The guide synthesizes existing literature and frameworks from the IPCC, UNEP, and OECD to offer flexible, actionable insights aimed at limiting global warming to 1.5 degrees Celsius.

• The waste sector, which includes both wastewater and solid waste, contributes roughly 20% of all human-caused methane emissions, totaling approximately 5.4 gigatons of carbon dioxide equivalents every year.
