UC Davis researcher finds ride-hailing EVs offer triple the emissions benefits of a personally owned EV

Green Car Congress

Replacing a gasoline-powered ride-hailing vehicle with an electric vehicle can deliver three times the carbon benefits of a personally owned electric vehicle, according to a study by a University of California, Davis, researcher of Uber and Lyft data. Ride-hailing vehicles travel more miles than personal vehicles, making them more efficient.

Emissions Analytics argues that current Pareto-efficient solution for decarbonization would be hybrids, not BEVs, based on do-no-harm

Green Car Congress

On this basis, and of Pareto efficiency, Emissions Analytics argues, until battery-electric vehicles can reach certain performance characteristics, government and industry support should switch immediately from EVs to full hybrids to create maximum welfare. The test cycle was made up of five repeats of the EQUA cycle, totalling 741 km.

Latest GHG Inventory shows California remains below 2020 emissions target; much steeper rate of GHG reductions required

Green Car Congress

California’s latest greenhouse gas data shows that while the state continues to stay below its 2020 target for emissions, there is much more work to do to achieve carbon neutrality by 2045. Source: California Air Resources Board (ARB). Total statewide 2018 GHG emissions were 425.3 Transportation emissions declined 1.5

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

Green Car Congress

But the cars and SUVs used in these situations drive more miles each year than a typical personal vehicle, contributing a higher proportion of greenhouse gases to the environment. Ridesharing apps are an increasingly popular way to travel around urban areas, especially for people without their own vehicles. 2c07030
