Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. Overall, electrification reduces net external costs to society by 3โ€“11% (5โ€“24ยข per trip), depending on the assumed social cost of carbon. —Mohan et al. Mohan et al.

Carbon emissions from generating electricity for electric vehicles vary greatly across the individual US states

Green Car Congress

by Michael Sivak, Sivak Applied Research The overall advantage of battery electric over gasoline vehicles, in terms of well-to-wheels emissions of greenhouse gases, has been well documented. However, the emissions of electric vehicles depend greatly on the energy source used to generate the electricity that powers them.

A Bamboo Carbon Filter for Diesels Could Reduce Emissions

Cars That Think

Although the pollutant emissions of a diesel engine are less than those of a gasoline one, it still emits carcinogens, nitrous oxides, and soot. Our groundbreaking activated-carbon-based filter represents a significant leap forward in environmental and economic efficiency,โ€ the electrical engineering student added.

Chalmers study: ban on sales of fossil-fuel cars greatly reduces lifecycle GHG mainly due to tailpipe emissions; risk of carbon leakage in manufacturing

Green Car Congress

If a ban were introduced on the sale of new gasoline and diesel cars, and they were replaced by electric cars, the result would be a significant reduction in lifecycle carbon dioxide emissions primarily due to reduced tailpipe CO 2 emissions, according to a new lifecycle study by researchers at Chalmers University of Technology, Sweden.
