Greenhouse Gas Mitigation
Reducing the output of greenhouse gas emissions remains the most critical strategy to mitigate climate change. Methane and hydrofluorocarbons (HFCs) contribute a significant amount of warming potential, though they are less well-known than carbon dioxide. While short-lived (lasting about 10 years in the atmosphere), methane is 35 times more damaging than CO2 over a century. States are looking at ways to limit the emission of methane and HFCs.

HFCs are the world’s fastest-growing climate pollutants, increasing globally by more than 10% each year.
In 2019, methane (CH4) accounted for about 10% of all U.S. greenhouse gas emissions from human activities.
Tackling methane emissions creates high-quality jobs that cannot be taken offshore.
