Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

The exponentially increasing global market share of EVs has prompted research on their efficacy in reducing greenhouse gases, but comparatively little effort has focused on their impact on air quality. coal, oil, natural gas, and biomass). —Schnell et al.

Study concludes that NG leakage higher than reflected in inventories; transportation fuel climate benefits questioned

Green Car Congress

In contrast to the “green light” for coal-to-NG substitution for power generation, the authors suggest that climate benefits from vehicle fuel substitution are uncertain (gasoline, light-duty) or improbable (diesel, heavy-duty).

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

Controlling soot from fossil fuels and solid biofuels may be a faster method of reducing Arctic ice loss and global warming than other options, including controlling CH 4 or CO 2 , although all controls are needed, according to a new study by Dr. Mark Z. Jacobson at Stanford University. He also found that soot emissions kill more than 1.5

MIT researchers conclude fundamental changes in the US energy-innovation system are needed to meet challenges of climate change and energy supply

Green Car Congress

Without systematic, transformative changes, the US is unlikely to succeed either in averting the worst economic and environmental consequences of climate change or in achieving a secure, affordable and reliable energy supply. The project was supported by a grant from the Doris Duke Charitable Foundation. —Richard Lester.

‘EVs will kill us all’ – Why are haters so obsessed with electric vehicles?

EV Central

I’m not easily shocked, but I do find the widely published work of Bjorn Lomborg, a Danish “author” and climate opinion giver, who is neither a climate scientist nor an economist, utterly dumbfounding. These heavy electric cars are also more dangerous for others in accidents. I’ll just pause here while you read that sentence again.
