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.

DOE: Life cycle GHG emissions for 2020 electric small SUV were half those of a conventional gasoline small SUV

Green Car Congress

C2G emissions are a sum of WTW emissions and emissions associated with vehicle manufacturing. The vehicle manufacturing cycle includes impacts of raw material extraction, vehicle parts production, assembly, as well as its disposal and related materials recycling processes.

UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

In a recent open-access paper published in ACS’ Environmental Science & Technology , researchers from the University of York report that alcohols in windshield washer fluid account for a larger fraction of real-world vehicle emissions than previous estimates have suggested.

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. Every air pollutant is more than 90% its limit.

Argonne report on characteristics of light-duty plug-in electric vehicles in US

Green Car Congress

A new report from a team at Argonne National Laboratory examines the changing characteristics for light-duty plug-in electric vehicles (PEVs) from 2010-2021, evaluating range, energy efficiency, costs, and performance. terawatt-hours of electricity to drive 19.1 billion miles, offsetting 700 million gallons of gasoline.

DOE tool allows consumers to estimate localized upstream greenhouse gas emissions for EVs and PHEVs

Green Car Congress

The US Department of Energy (DOE) has published a Beyond Tailpipe Emissions Calculator that provides estimates of total greenhouse gas (GHG) emissions associated with driving an electric vehicle (EV) or plug-in hybrid electric vehicle (PHEV), including emissions from the production of electricity used to power the vehicle.
