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.

California ARB greenlights states GHG cap-and-trade program

Green Car Congress

The cap-and-trade program also works in concert with other measures, such as standards for cleaner vehicles, low-carbon fuels, renewable electricity and energy efficiency, and complements and supports California’s existing efforts to reduce smog-forming and toxic air pollutants. Click to enlarge.

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

Green Car Congress

The major sources of methane in California are livestock (~30% of the state’s methane emissions), followed by landfills and oil and gas production. Methane is 72 times more efficient at trapping heat in the atmosphere than CO 2 , which is the most prevalent global warming gas. CO 2 remains in the atmosphere for up to a century.

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

Controlling soot from fossil fuels and solid biofuels may be a faster method of reducing Arctic ice loss and global warming than other options, including controlling CH 4 or CO 2 , although all controls are needed, according to a new study by Dr. Mark Z. That ranks the effects of soot ahead of methane, an important greenhouse gas.

Calif. ARB releases GHG scoping plan update; more ZEVs, “LEV IV”, MD and HD regulations; ZEV for trucks; more LCFS

Green Car Congress

The California Air Resources Board released the draft proposed first update to the AB 32 Scoping Plan, which guides development and implementation of California’s greenhouse gas emission reduction programs. The Air Resources Board is required to update the Scoping Plan every five years.

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

Green Car Congress

The global economic crisis 2007/2008 only temporarily reduced emissions. Scenarios show that to have a likely chance of limiting the increase in global mean temperature to two degrees Celsius, means lowering global greenhouse gas emissions by 40 to 70% compared with 2010 by mid-century, and to near-zero by the end of this century.

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

Green Car Congress

The California Air Resources Board released its proposed greenhouse gas cap-and-trade regulation. 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. Offset Protocols.
