Our results suggest that gas-aerosol interactions play an important role in methane’s GWP, and hence our larger value would allow better optimization of climate change mitigation policies. Methane’s GWP may also change with time as air quality regulations alter the background state of tropospheric chemistry. Shindell et al.

R134a replaced CFC-12 as the MAC refrigerant in the early 1990s due to the negative impact of CFCs on the Earth’s ozone layer. With its GWP of 1, it is also the refrigerant that has the least impact on climate. It has a high cooling capacity and is available worldwide at low cost in the required qualities.

These are low-cost reductions in global warming pollution that can be secured by devoting approximately 5% of the allowance value to the program. The draft allows covered entities to increase their emissions above their allowances if they can obtain “offsetting” reductions at lower cost from other sources.
