Study finds that current approach to limiting wintertime pollution may initially backfire

Green Car Congress

A key control strategy is to reduce emissions of the limiting reagent. This is contrary to what is typically assumed and suggests a new way to mitigate this type of pollution in Salt Lake City, Denver and beyond. Denver often has the same problem in winter, when brown clouds hang over the city. —Womack et al. Womack, C.

ICCT quantifies the EV charging infrastructure gap across US markets

Green Car Congress

The largest charging gaps are in markets where electric vehicle uptake will grow most rapidly, including in many California cities, Boston, New York, Portland, Denver, and Washington, D.C. Planned infrastructure deployment activities are promising, but uneven. Increased charger utilization brings infrastructure investment opportunities.
