Study quantifies impact of oil and gas emissions on Denver’s ozone problem

Green Car Congress

The first peer-reviewed study to directly quantify how emissions from oil and natural gas (O&NG) activities influence summertime tropospheric ozone (O 3 ) pollution in the Colorado Front Range confirms that chemical vapors from oil and gas activities are a significant contributor to the region’s chronic ozone problem.

Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.

Study finds that current approach to limiting wintertime pollution may initially backfire

Green Car Congress

The processes that create ozone pollution in the summer can also trigger the formation of wintertime air pollution, according to a new study from researchers at the University of Colorado Boulder and NOAA, in partnership with the University of Utah. Denver often has the same problem in winter, when brown clouds hang over the city.

NASA satellite images highlight US air quality improvement with reduction of NO2

Green Car Congress

After ten years in orbit, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite has been in orbit sufficiently long to show that people in major US cities are breathing less nitrogen dioxide. New NASA satellite images released this week demonstrate the reduction of air pollution across the US.

Junkyard Find: 1993 Nissan Stanza Altima GXE

The Truth About Cars

Finally, in a Denver-area boneyard , I found this battered '93 GXE sedan. There's no mention of the Stanza name in this TV commercial Ozone-friendly air conditioning! In any case, the Altima is an icon now, and I've spent years trying to find a first-year example in the car graveyards I frequent. It passed the Lexus ball-bearing test.

EPA proposes air pollution standards for oil and gas drilling operations; focus on capture of escaping natural gas

Green Car Congress

The VOC reductions in the proposal are expected to help reduce ozone nonattainment problems in many areas where oil and gas production occurs. As part of the public comment period, EPA will hold three public hearings, in the Dallas, Denver and Pittsburgh areas. Details on the hearings will be announced soon.
