Methane is a powerful greenhouse gas that contributes to climate change. By reducing methane emissions from various sources like livestock, rice fields, and coal mines, we can make a significant impact on global warming. The cost-effective approach outlined in the report shows that investing in methane mitigation can lead to substantial benefits, with the potential to reduce emissions by 1.5 to 1.9 billion tons at a cost of $14 to$30 billion. This rapid response can help limit global temperature rise to less than 2°C by 2100, making it a crucial part of effective climate action.
