California Air Resources Board posts revised draft of strategy to reduce “Super Pollutants”

Green Car Congress

The California Air Resources Board (CARB) has posted a revised draft of California’s proposed Short-Lived Climate Pollutant (SLCP) Strategy. SLCPs are a category of pollutants which remain in the atmosphere for a relatively brief period, but have global warming potentials that are much higher than those of CO 2.

Tsinghua/Argonne Study Finds That Mass Use of EVs in China Could Result in Higher CO2 and Criteria Pollutant Emissions Than Conventional and Hybrid Gasoline Vehicles Due to Coal-Fired Generation of Electricity

Green Car Congress

The study examined the fuel-cycle CO 2 , SO 2 , and NO x emissions of EVs in China in both current (2008) and future (2030) periods and compared them with those of conventional gasoline vehicles and gasoline hybrids.

California ARB moves forward with climate and air quality actions

Green Car Congress

CARB also adopted a new plan to curb destructive “super pollutants” including black carbon, fluorinated gases and methane. 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.

California ARB Holding Public Meeting on Possible Revamp of Zero Emission Vehicle Regulation; ZEV II

Green Car Congress

ARB Staff’s analysis shows ZEVs will need to reach 100% of new vehicle sales between 2040 and 2050, with commercial markets for ZEVs launching in the 2015 to 2020 timeframe, to meet the 80% GHG reduction target set by the Governor.

EPA: US greenhouse gases up 2% in 2013; increased coal consumption, cool winter

Green Car Congress

Additionally, relatively cool winter conditions led to an increase in fuels for the residential and commercial sectors for heating. By sector, power plants were the largest source of emissions, accounting for 31% of total US greenhouse gas pollution. Climate Change Emissions' Transportation sector GHG emissions 1990-2013.

Report for IPCC finds renewables could supply up to 77% of global energy by 2050 under most optimistic scenario; need for enabling public policies and investments

Green Car Congress

Up to 77% of the world’s energy supply could be met by six key renewables by mid-century under the most optimistic scenario if backed by the right enabling public policies, according to a new report by more than 120 researchers working with the Intergovernmental Panel on Climate Change (IPCC).

Marine Scientists Issue Monaco Declaration Calling for Immediate Action to Reduce Ocean Acidification

Green Car Congress

The ocean absorbs CO 2 from the atmosphere at a rate of more than 20 million tons per day, thus removing one-fourth of the anthropogenic CO 2 emitted to the atmosphere each year and reducing the climate-change impacts of this greenhouse gas. However, when CO 2 dissolves in seawater, it forms carbonic acid. 2007; Tyrrell et al.,
