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. This extra vehicle travel increases estimated congestion, crash risk, and noise externalities by 2–3% (2–3¢ per trip). —Mohan et al. Mohan et al.

Two-year study in Canada finds large trucks disproportionately contribute to higher levels of black carbon pollution

Green Car Congress

A two-year study led by researchers at the University of Toronto has found large trucks to be the greatest contributors to black carbon emissions close to major roadways. This was in part due to differences in wind and proximity to the road but, surprisingly, the number of vehicles didn’t make that much of a difference.

A Bamboo Carbon Filter for Diesels Could Reduce Emissions

Cars That Think

Diesel cars are a popular choice for those looking to buy a used vehicle in Asia, Europe, and elsewhere. Although the pollutant emissions of a diesel engine are less than those of a gasoline one, it still emits carcinogens, nitrous oxides, and soot. Older models don’t even have the emission-control features that newer ones do.
