WUSTL study finds use of air conditioning reduces in-car pollution

Green Car Congress

AUGUST 11, 2017

Traffic is a major source of harmful pollutants; daily peak exposures tend to occur near roadways or while traveling—or being stuck—on them. That gave them rare, real-world look at pollutant exposure. With windows closed, the pollutants took longer to enter the vehicle cabin, but also longer to exit it.

Because the LCFS also reduces toxic air pollution emitted by cars, this program minimizes health impacts in communities that live near freeways. The vehicle stock and energy demand model is based on VISION 2014, with some elements updated for the report using data from VISION 2017.

Broadly, the study by Stephanie Searle, Francisco Posada Sanchez, Chris Malins, and John German concludes that (a) technical barriers do not prevent the use of higher blends of ethanol, and (b) slow uptake of blends such as E15 and E85 is due to other factors, including high cost, legal and warranty issues, and consumer awareness and acceptance.

OCTOBER 31, 2017

Substantial emission reductions due to fuel economy standards for passenger cars are already included in the current policy scenario. The report also covers an assessment of the potential contribution from reductions in short-lived climate pollutants (SLCPs). A shift to more electric vehicles is also included.
