Today, the Obama administration is expected to release new cleaner tailpipe standards that will reduce smog-forming pollution, save lives and improve public health.
These new safeguards will require that oil refineries reduce the sulfur content of gasoline and that automakers use advanced technology to slash tailpipe emissions of health-threatening air pollution.
Today, more than one in three American children live where air is dangerous to breathe because of smog, particulate matter, and other hazardous pollutants, much of which come from the tailpipes of our cars and trucks.
By lowering the sulfur content of gasoline, the "Tier 3" cleaner tailpipe standards have the potential to cut major contributors to smog-forming ozone and pollution - nitrogen oxides and volatile organic compounds. In 2017, when these standards take effect, they will reduce emissions of nitrogen oxide (a smog creating pollutant) by 260,000 tons per year, the equivalent of taking 33 million cars off the road.
