New international Climate and Clean Air Coalition to focus on reduction of short-lived climate pollutants

Green Car Congress

Global benefits from full implementation of measures for reduction of short-lived climate pollutants in 2030 compared to the reference scenario. The climate change benefit is estimated for a given year (2050) and human health and crop benefits are. A substantial part of these cuts can be done at little or no net cost.

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. Shindell et al.

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.

Study Concludes that Rocket Launches May Need Regulation to Prevent Ozone Depletion

Green Car Congress

The global market for rocket launches may require more stringent regulation in order to prevent significant damage to Earth’s stratospheric ozone layer in the decades to come, according to a new study by researchers in California and Colorado. Darin Toohey.
