Given the short-term potency of methane, cost-effective interventions to reduce methane emissions should be an immediate priority for the sectors with the largest emissions. The agriculture, energy, sanitation and waste sectors are collectively responsible for 90-95% of global anthropogenic sources of methane:
- Agriculture accounts for ~41% of methane emissions from human activity, including from rice cultivation and agriculture waste burning, manure management, and gas from cows and sheep;
- Energy accounts for ~35%, including from oil and gas extraction, pumping, transport and coal mining;
- Sanitation and waste account for ~20%, including from landfills and wastewater treatment.
