Wironen publishes Info Note on climate metrics for methane mitigation in agriculture

Michael Wironen co-authored an Info Note on CGIAR exploring the implications of the climate metric Global Warming Potential (GWP) for methane mitigation in agriculture. 

Key takeaways include:

• Using GWP complements conventional climate metrics because it better describes the actual warming caused by methane (CH4) emissions.
• A sustained ~0.35% annual decline in CH4 from 2020-2040 would be sufficient to stop further increases in global temperatures due to agricultural CH4 emissions. This is analogous to the impact of net-zero CO2 emissions.
• Application of GWP to CH4 emissions accounting suggests that avoiding further warming due to Ch4 emissions in agriculture is more attianable than previously understood. 
• CH4 reductions can have a rapid and highly substantial impact, which underscores the importance of making significant cuts in CH4 emissions immediately.
