HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. A binding legal agreement exists that can cut HFCs now—the Montreal Protocol ozone treaty—and many alternatives to HFCs have already been developed and are waiting for the right regulatory incentive from the Montreal Protocol to be deployed.

These were shown to be ozone-depleting, however, and were targeted for phasing out under the 1987 Montreal Protocol. However, HFC-134a, while having zero ozone-depletion potential, has a very high global warming potential—more than 1,500 times as much warming as an equivalent amount of CO 2.

The basic question addressed, which appears on the study homepage (epri-reports.org) is this: How would air quality and greenhouse gas emissions be affected if significant numbers of Americans drove cars that were fueled by the power grid? And the grid is getting cleaner and more renewable every year. I truly hope we have turned a corner.

A new study from UC Berkeley confirms what EV fans already know: EV adoption does, in fact, make the air cleaner.

And so if you look at the Earth from space and you see that shiny blue marble, the principle is that if you could make the atmosphere or the Earth about 1% more reflective, that you might be able to offset a doubling of CO2 or two or more degrees of warming. And that was based on observations of volcanoes.
