In the US, Life Cycle Emissions For EVs Are Already 60-68% Lower Than Gasoline, Study Finds

An anonymous reader quotes a report from Ars Technica: Today in the US market, a medium-sized battery EV already has 60-68 percent lower lifetime carbon emissions than a comparable car with an internal combustion engine. And the gap is only going to increase as we use more renewable electricity. That finding comes from a white paper (PDF) published by Georg Bieker at the International Council on Clean Transportation. The comprehensive study compares the lifetime carbon emissions, both today and in 2030, of midsized vehicles in Europe, the US, China, and India, across a wide range of powertrain types, including gasoline, diesel, hybrid EVs (HEVs), plug-in hybrid EVs (PHEVs), battery EVs (BEVs), and fuel cell EVs (FCEVs).

The study takes into account the carbon emissions that result from the various fuels (fossil fuels, biofuels, electricity, hydrogen, and e-fuels), as well as the emissions that result from manufacturing and then recycling or disposing of vehicles and their various components. Bieker has also factored in real-world fuel or energy consumption -- something that is especially important when it comes to PHEVs, according to the report. Finally, the study accounts for the fact that energy production should become less carbon-intensive over time, based on stated government objectives. The life cycle emissions of battery EVs in Europe today at 66-69 percent lower than a comparable gasoline-powered car. China is at 37-45 percent fewer emissions for BEVs, and India shows 19-34 percent.

As for fuel cell EVs (FCEVs), they 'are only abut 26-40 percent less carbon-intensive than a comparable gasoline vehicle,' notes Ars. 'But if hydrogen was produced using renewable energy rather than steam reformation of natural gas, that number would jump to 76-80 percent -- even better than a BEV's numbers.'
