CUTTING METHANE

The report identifies methane as a critical target for slowing climate change due to its high warming potential and short atmospheric lifetime. It highlights significant discrepancies between 'bottom-up' government estimates and 'top-down' satellite measurements, particularly in the energy sector. The document details mitigation strategies such as leak detection and repair (LDAR) in oil and gas, alternative livestock feeds, and alternate wetting and drying in rice cultivation. It also emphasizes the role of biogas and food waste reduction as cross-cutting solutions for the agriculture and waste sectors.

• Methane is a highly potent greenhouse gas that contributes to at least 30% of current global warming, trapping over 80 times more heat than carbon dioxide over a 20-year period, though it dissipates much faster with an atmospheric lifetime of about 12 years.
• There are substantial gaps between reported methane emissions and actual measurements; the IEA found global energy sector emissions are approximately 70% higher than national inventories, while some U.S. gas facility measurements were 60% higher than EPA estimates.
• Human activity accounts for about 60% of global methane emissions, with the primary anthropogenic sources being agriculture (40%), the energy sector (35%), and waste management (20%).
• The energy sector offers the most immediate potential for reductions; the IEA suggests it is technically possible to reduce the sector's emissions by 75%, with nearly half of those reductions achievable at no net cost due to the value of the captured gas.
• In agriculture, specific interventions can significantly cut emissions: adding red algae (Asparagopsis taxiformis) to beef cattle diets can reduce digestive methane by 80%, and alternating irrigation and draining in rice paddies can reduce emissions by up to 70%.
• Biogas capture serves as a cross-cutting solution for waste and agriculture; in the U.S., there are 538 operational landfill gas projects that can capture 60-90% of a landfill's methane emissions.
