When in the air, these compounds may combine with volatile organic compounds to produce ozone, the main component of smog. The grime exposed to a “solar simulator” shed more nitrates than the grime left in the dark, suggesting that light can chemically convert nitrogen compounds back into active forms that can return to the atmosphere.
Illustration of light-duty vehicle sales share by emission certification level projected to be required to meet. The existing LEV II program regulates emissions from new light-duty vehicles, including include all passenger cars, light trucks, and medium-duty passenger vehicles. proposed NMOG+NO x standards in new LEV III.
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.
ARB staff developed this strategy using a multi-pollutant scenario planning tool ( Vision 2.0 ) that quantifies changes in ozone and PM 2.5 Projected statewide light duty vehicle technology mix.

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.
In light of this situation, there's increasing talk of actions that governments can take beyond reducing greenhouse gas emissions—actions that could either remove existing greenhouse gases from the atmosphere or reduce the amount of sunlight coming into the atmosphere. Hardly the breakthroughs we need to stave off disaster.
Meanwhile, environmentalists were voicing concern—about how noisy such aircraft are taking off, about the possibility that their high-altitude emissions would erode the ozone layer, and about how disruptive the sonic booms would be. The key concept is a phenomenon known as Mach cutoff , the physics of which is straightforward.
In a small set of close-cropped teaser photos, Kia showed that the production EV3 preserves many of the same bold design traits and so-called Star Map lighting theme as the concept. While recent EPA emissions rules for passenger cars and commercial trucks will help clean up particle pollution, ozone pollution remains a challenge.
