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. In cities such as Denver, NO x comes primarily from vehicle tailpipes.

Modelling the Impact of PHEVs on Ozone in Denver

Green Car Congress

Researchers at the University of Colorado, Boulder and the National Renewable Energy Laboratory (NREL) modeled the emissions impact had plug-in hybrid electric vehicles (PHEVs) replaced light duty gasoline vehicles in the Denver, Colorado area in summer 2006. Ozone concentration increases were modeled for small areas near central Denver.

Study concludes air pollution directly affects cognition

Green Car Congress

Results of new analysis conducted by German and Swiss researchers suggests that air pollution directly affects cognition and is not mediated by lung function; put another way, the two are independent risk factors for cognitive decline.

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. The team’s unexpected finding, published in the journal Geophysical Research Letters , suggests that in the US West and elsewhere, certain efforts to reduce harmful wintertime air pollution could backfire.

Today, operating the best-selling gas-powered commercial leaf blower for one hour emits air pollutants comparable to driving a 2017 Toyota Camry from Los Angeles to Denver. SORE are engines that produce 25hp or less, but emit high levels of air pollutants, including oxides of nitrogen (NO x ), reactive organic gases (ROG), and particulate matter (PM). It’s time to phase out these super polluters.

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

Green Car Congress

The US Environmental Protection Agency (EPA) proposed standards to reduce harmful air pollution from oil and gas drilling operations. As part of the public comment period, EPA will hold three public hearings, in the Dallas, Denver and Pittsburgh areas. These proposed updated standards—which are being issued in response to a court order—would rely on cost-effective existing technologies to reduce emissions.
