The Northwestern team, with colleagues from Boston University and the NOAA Geophysical Fluid Dynamics Laboratory in Princeton combined climate modeling with public health data to evaluate the impact of electric vehicles on US lives and the economy. Results show that in more aggressive scenarios—i.e.,

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? about 0.6 °C.

Mikhail Chester and Arpad Horvath inventoried on-road, rail, and air travel to determine energy consumption, greenhouse gas (GHG) emissions, and criteria air pollutant (CAP) emissions (excluding PM, lead, and ozone due to lack of data). 83% of rail passenger kilometers are performed by metropolitan systems (with Amtrak serving the remaining).

Meanwhile, environmentalists were voicing concern—about how noisy such aircraft are taking off, about the possibility that their high-altitude emissions would erode the ozone layer, and about how disruptive the sonic booms would be. The last of these issues was perhaps the most vexing, prompting the U.S.
