Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? cancel the launch.

California ARB moves forward with climate and air quality actions

Green Car Congress

The plan, California’s Short-lived Climate Pollutant Reduction Strategy, maps out the route to more rapid greenhouse gas reductions by clamping down on these super pollutants. Approximately 70% of the reductions needed to meet the ozone standard in the South Coast in 2031 would come from existing or proposed regulatory actions.

EPA proposes stringent new emissions standards for light-, medium-, heavy-duty vehicles for MY 2027 and beyond

Green Car Congress

Second, EPA is proposing to remove refrigerant-based AC provisions for both light- and medium-duty vehicles because, under a separate rulemaking, EPA has proposed to disallow the use of high global warming potential refrigerants. The proposed standards are also projected to accelerate the transition to electric vehicles.

IPCC: GHG emissions accelerating despite mitigation efforts; major institutional and technological change required to keep the heat down

Green Car Congress

Decomposition of the decadal change in total global CO 2 emissions from fossil fuel combustion by four driving factors; population, income (GDP) per capita, energy intensity of GDP and carbon intensity of energy. The global economic crisis 2007/2008 only temporarily reduced emissions. WG III Summary for Policymakers. Click to enlarge.

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

The bill also establishes an interagency council to ensure an integrated federal response to adapting to the effects of global warming. The bill also modifies the Clean Air Act to require the development of greenhouse gas emissions standards for all other mobile sources—e.g., trucks, construction machines, ships and planes.

Researchers describe the “where” and “when” of life cycle emissions from gasoline and ethanol in the US

Green Car Congress

Life cycle inventories have typically been presented at global, national, or regional levels—sufficient for understanding global processes such as climate change and fossil fuel depletion, but insufficient for the analysis of local processes such as air pollution, according to the researchers. the contiguous US).
