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?

Inventorying criteria air pollutants showed that vehicle non-operational components often dominate total emissions. Life-cycle criteria air pollutant emissions are between 1.1 In terms of GHG emissions, large aircraft on a total g CO 2 e/PKT basis outperforms Boston light rail (the Green Line).

The Soviet Union's Tupolev TU-144, which could fly just as fast and had been used to transport mail and freight the previous year, began carrying passengers in 1977. The main obstacles will be regulatory and, especially, environmental: Supersonic airliners could be hugely more polluting than their subsonic counterparts.

I mean, when the electricity it uses is produces, pollution still happens, just not "right from your car"? Having centralized energy production in that way allows for centralized pollution control measures, filters, so-called "clean coal" rather than depending on X number of cars, manufacturers, and consumers to deal with pollution control.
