Why do GWP20 and GWP100 choices change the carbon story?
sourced
Methane's global warming potential is about 28-30 over 100 years but roughly 80 over 20 years, so near-term accounting makes methane avoidance look far more valuable than long-term accounting does. Manure-based pathways show the largest gap between the two, which means the chosen horizon materially changes the claim being made.
