Methane Abatement in Sustainable Taxonomies

This executive summary outlines a practical roadmap for policymakers and taxonomy developers to integrate methane reduction objectives into sustainable finance frameworks. It identifies specific abatement measures for four high-potential sectors—energy, agriculture, solid waste, and wastewater—and establishes minimum requirements for leakage detection and repair (LDAR) to ensure environmental integrity and investor confidence.

• Investment in methane abatement is significantly lower than required, with annual investment dropping from less than USD 14 billion in 2021/22 to approximately USD 6 billion in 2023, compared to an estimated annual need of USD 48 billion through 2030.
• Sustainable finance taxonomies can catalyze methane mitigation by accelerating funds for mature applications, prioritizing harder-to-finance solutions in diffuse sectors, and reducing perceived risks and funding costs through consistent signals.
• Best practices for the energy sector include the use of Leakage Detection and Repair (LDAR) and specific lifecycle GHG emission thresholds for bioenergy, such as a maximum of 36.6 gCO2eq per MJ for electricity generation.
• In the agriculture sector, recommended abatement measures include dietary manipulation and selective breeding for livestock, implementing irrigation practices that reduce flooding days by at least 10% for rice production, and preventing intentional burning of peatlands and forests.
• For solid waste and wastewater, best practices emphasize the transition of flaring-only systems to value-added use within 3 years and the requirement for airtight storage of digestate for at least 50 + x days (where x is 2 days per mass percent of non-manure-based feedstock).
• Minimum requirements for Leakage Detection and Repair (LDAR) systems include mandatory third-party revision for credibility, at least one monthly visual inspection of high-risk components, and mandatory repairs if leaks exceed 2% of annual production or 50 tonnes per year.
