What Are the Life Cycle Pollution Impacts from Electric Cars?


Life cycle air quality impacts of conventional and alternative light-duty transportation in the United States (6 page pdf, Christopher W. Tessum, Jason D. Hill, and Julian D. Marshall, Proceedings f the Ntional Academy of the United States of America (PNAS), Dec. 15, 2014)

Today we review a paper that compares the amount of pollution (as PM2.5 and ozone) produced in generating power for electric powered vehicles compared with the use of conventional gasoline. Results indicate that the use of biofuels (such as ethanol from corn) increases health impacts from pollution by 80% while using renewable sources such as natural gas, wind, water or solar reduces the impact by 50% (noting that natural gas is a pollutant in terms of climate change). This study underlines the lack of benefits from biofuels in terms of pollution and health.
