California ARB releases final version of proposed update to Climate Change Scoping Plan; LEV IV

Green Car Congress

the final version of the proposed First Update to the Climate Change Scoping Plan (First Update). Achieving our long-term climate goal and 2032 ozone standards will require a much deeper penetration of ZEVs into the fleet. The California Air Resources Board (ARB) has released. The draft version was released in February.

World Bank to focus on reducing short-lived climate pollutants; transport projects

Green Car Congress

A new report prepared by the World Bank at the request of the G8 identifies ways that the World Bank can do more through its projects to reduce the emission of short-lived climate pollutants (SLCPs): black carbon, methane, tropospheric ozone, and fluorinated gases known as HFCs. Over the six-year period of the review (FY2007-2012), 7.7

Study finds warming caused by synthetic greenhouse gases could outweigh climate benefits from phasing down CFCs

Green Car Congress

An international team examining the total warming impact of 25 major synthetic greenhouse gases (SGHGs) has concluded that without additional limits on SGHG use, the resulting increase in warming could outweigh the climate benefits gained thus far from phasing down chlorofluorocarbons (CFCs).

NSF issues solicitation for decadal and regional climate prediction using Earth Systems Models

Green Car Congress

The US National Science Foundation has issued a solicitation for Decadal and Regional Climate Prediction using Earth System Models (EaSM). NSF anticipates funding of $35,000,000 to $39,000,000 in FY 2012 and FY 2013, pending availability of funds, to be awarded to an estimated 7 to 12 projects. —NSF EaSM solicitation.

International study identifies 14 key measures to reduce methane and black carbon emissions; reduction in projected global mean warming of ~0.5 °C by 2050

Green Car Congress

Circle areas are proportional to values for (A and B) climate change, (C and D) human health (values for population over age 30), and (E and F) agriculture. Methane is both a potent greenhouse gas and an important precursor to ground-level ozone. National benefits of the CH 4 plus BC measures versus the reference scenario.

California Air Resources Board adopts GHG cap-and-trade program; first auctions slated for Aug/Nov 2012

Green Car Congress

The cap-and-trade joins a suite of other major climate program measures including standards for ultra-clean cars (Advanced Clean Cars, earlier post ), low-carbon fuels (Low Carbon Fuel Standard, earlier post ) and renewable electricity. The cap will be set in 2013 at about 2% below the emissions level forecast for 2012. Earlier post.)

Field study finds soot particles absorb significantly less sunlight than predicted by models; climate models may be overestimating warming by BC

Green Car Congress

Although viewed as a potential target in the global effort to reduce climate change, atmospheric black carbon particles absorb significantly less sunlight than scientists have predicted, according to a new study by an international team of researchers, published in the journal Science. —Cappa et al.
