On the way to work today I passed a Manhattan Beer Distributors trucks making a drop-off. On the back of the truck read "A Breath of Fresh Air!" and then I noticed a green sticker that said this truck uses Compressed Natural Gas or CNG. Having no idea what that was I looked it up is a substitute for gasoline. It is considered to be an environmentally "clean" alternative to those fuels. It is made by compressing natural gas (which is mainly composed by methane), in a percantage range of 70% to 98%). http://en.wikipedia.org/wiki/Compressed_natural_gas
The company, headquartered in the Bronx, operates a fleet of over 500 trucks, vans,
sedans and forklifts and is trying to lower thier emissions all over the city. Here is an interesting article about thier efforts . . . http://www.nyserda.org/Programs/Transportation/case%20studies/Manhattan_Beer.pdf
