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

Green Car Congress

In particular, the study led by Drew Shindell found that methane emissions have a larger warming impact due to those interactions than accounted for in current carbon-trading schemes or in the Kyoto Protocol. Methane’s GWP may also change with time as air quality regulations alter the background state of tropospheric chemistry.

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.

Study suggests cap and trade programs do not provide sufficient incentives for energy technology innovation; implications for climate policy

Green Car Congress

Policies incentivizing the private sector to push to develop innovative “clean” technologies are likely to play a key role in achieving climate stabilization. Respectively, Title IV of the 1990 Clean Air Act and the Ozone Transport Commission/NO x Budget Program.).

ARB releases proposed cap-and-trade regulation for comment; transportation fuels impacted in 2015

Green Car Congress

A key part of ARB’s AB 32 Scoping Plan ( earlier post ), the cap-and-trade program provides an overall limit on the emissions from sources responsible for 85% of California’s greenhouse gas emissions. The program is expected to reduce GHG emissions between 18 and 27 MMTCO 2 e in 2020. Over time, the cap will steadily decline.

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.
