Methane Mitigation – Novel Approaches to Reduce Methane Emissions and Remove Atmospheric Methane
Session ID#: 252252
Session Description:
Methane is the second-most important greenhouse gas due to its high Global Warming Potential of 84 over 20 years and 30 over 100 years. Effective mitigation of methane emissions and removal of atmospheric methane can therefore be fast-acting levers to slow climate change. Currently, anthropogenic sources are estimated to contribute 60% of global emissions, with natural sources responsible for the remaining 40%. Natural emissions are projected to rise as temperatures warm, particularly from wetlands, freshwater systems, and thawing permafrost. Several strategies for destroying methane at its sources are being developed, including through biotic and abiotic processes. However, no technologies exist yet for mitigating dilute methane emissions (either natural or anthropogenic such as rice paddies and dairy barns). We welcome submissions that explore new approaches for methane mitigation, including applications at emission sources and removal of atmospheric methane.
