Re: “High-Speed Rail Is Definitely Green

"One of the ways the UC Berkeley study measures the environmental impact of travel by car, airplane, and high-speed rail is by determining the level of emissions produced per passenger per vehicle kilometers traveled. Cars have the biggest footprint. A 2009 Federal Highway Administration report showed that there were about 380 billion annual vehicles per kilometer traveled in California, and this number is forecast to increase to 480 billion by 2040 absent a high-speed rail system. That's another one hundred billion car trips in the state in the next thirty years, spewing out another one hundred billion trips' worth of tailpipe emissions."

i like the idea of high-speed rail so it's frustrating to see a paragraph like this in an article in favor of it. are we talking about vehicle-kilometers or vehicles per kilometer? are we talking about annual numbers or a 30-year span? big numbers are thrown at us but what do they mean?
