Philadelphia Inquirer: Scientists Hail the Bus as the Greenest Way to GO
The last time I took a trip on a bus, it wasn't pretty. It was merely cheap. But that was a few decades ago, and now I have good reason to try again. In a 54-page data-laden study, the Union of Concerned Scientists has concluded that traveling by bus - or, as they term it, motorcoach - is the greenest option. In every scenario they calculated - from a single person going 100 miles to four people going 1,000 miles - the bus was better.
Retrofitting public buildings to be greener would create as many as 800,000 jobs.
