Moses Ting's inspiration and design notebook.
From the Nov/Dec issues of I.D. magazine:
Thanks to modern computer-controlled turbodiesel engines and today’s low-sulfur diesel fuel, long-distance bus travel creates the least pollution per passenger mile of any means of transportation short of bicycle or boot. At about 0.2 pounds of carbon per passenger mile, intercity buses bean even the Prius. “Greener than a hybrid” could be Greyhound’s motto.
Lucky for me, I live in NY. Where one can take an intercity bus to pretty much any major cities in the Northeast.
