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.

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 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. New NASA-funded research has devised a way to use satellite measurements of the precursor gases that contribute to ozone formation to differentiate among three different sets of conditions that lead to its production.

How Engineers Can Help Protect Earth From Worsening Climate Change

Cars That Think

The climate crisis is also having a severe effect on the planet, which is being battered by pollution, deforestation, and soil degradation. Ninety-nine percent of the global population breathes in air that exceeds WHO-guideline limits on pollutants, with low- and middle-income countries suffering from the highest exposures.

Daimler partnering to transfer its latest generation of automotive fuel cell technology to stationary applications

Green Car Congress

Recently, it presented the next step with pre-production models of the Mercedes-Benz GLC F‑CELL. Efficient management of energy and material resources also applies to all components used in electromobility. Daimler’s sustainability approach, within the context of implementing “CASE” goes far beyond the automotive product.

Study finds vehicles more important source of urban atmospheric ammonia than farms

Green Car Congress

Vehicle tailpipes are a more important source of ammonia’s contribution to urban air pollution than is agriculture, according to a study by researchers from the US and China. The paper is published in the ACS journal Environmental Science & Technology. Kang Sun, Lei Tao, David J. Miller, Da Pan, Levi M. Golston, Mark A. Zondlo, Robert J.
