Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.

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. Jacobson at Stanford University. He also found that soot emissions kill more than 1.5

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. Short-lived climate pollutants (SLCPs) make up about 12% of GHG emissions, but strong actions to reduce them could help reduce global warming by as much as 40%.

By 2050, HFC emissions could equal up to 19% of global CO 2 emissions under business-as-usual scenarios. From Molina et al. Earlier post.) Mario Molina. (Dr.

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. SLCPs may account for an estimated 40% of global warming, increasing the impacts of climate change. CO 2 remains in the atmosphere for up to a century.

In order to achieve the 2008 Ozone National Ambient Air Quality Standards set by US EPA, CARB estimates that the South Coast Air Basin alone (including Los Angeles) will need an 80% reduction in NO x emissions by 2031. CARB said it looked forward to continued cooperation with the federal agencies on this long-term effort.

Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. From 2007 to 2008, the share of ethanol in global gasoline type fuel use was estimated to increase from 3.78% to 5.46%, and the share of biodiesel in global diesel type fuel use from 0.93% to 1.5%.
