The California Air Resources Board (ARB) will host a public workshop to discuss regulatory concepts to reduce NO x emissions from new on-road heavy-duty vehicles greater than 10,000 pounds gross vehicle weight rating. Warranty corrective action.

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.

Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. An 80% reduction of GHG emissions is targeted for 2050, relative to 1990 levels. Click to enlarge.

Medium- and heavy-duty on-road trucks and buses are a significant source of emissions of greenhouse gases (GHG); diesel particulate matter 2.5 microns or less (PM 2.5 ); and NO x emissions that lead to ozone and secondary PM. Statewide, they are responsible for 35% of the NO x emissions, 26% of the PM 2.5

The majority of California residents live in areas that do not meet permissible air quality levels for regulated air pollutants—mostly due to exceedances in atmospheric concentrations of ozone and particulate matter. Vehicles that are engine certified include incomplete gasoline vehicles and those powered with diesel engines.

ARB staff developed this strategy using a multi-pollutant scenario planning tool ( Vision 2.0 ) that quantifies changes in ozone and PM 2.5 precursor emissions; GHG emissions; petroleum usage; and diesel toxics emissions as various technologies become widespread in vehicle and equipment fleets. Vision 2.0 Heavy-duty vehicles.

The deadline to submit research concepts is 31 January 2012. Development of sustainable communities strategies can also provide an opportunity for associated criteria pollutant emission reductions that will be needed to attain air quality standards for ozone and particulate matter as well as reduce near-roadway exposures.
