NASA GISS Study Finds That Methane Has an Elevated Warming Effect Due to Interactions With Aerosols

Green Car Congress

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. Drew Shindell.

House Chairmen Waxman, Markey Release Draft of Energy and Climate Legislation; Among the Many Provisions Are Cap-and-Trade, Harmonization of CAFE and California Vehicle Regulations, and Low Carbon Fuel Standard

Green Car Congress

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. Strategic Reserve.

Volkswagen to use CO2 as refrigerant for future air conditioning systems

Green Car Congress

The Volkswagen Group announced that it is choosing CO 2 as the future low global warming potential (GWP) refrigerant for its mobile air conditioning (MAC) systems. 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. Earlier post.).
