I think we all know that cars are one of the worst polluters on the planet today, and so I find it nice of Nissan to introduce the greener Leaf, a car that has zero emissions.  The Nissan Leaf has a lithium ion battery-powered chassis that is good for 160km (100 miles) on a single charge.  Best of all, its lack of a tailpipe can reduce one’s “carbon footprint” significantly.  I don’t have a price for it yet, but it should be “affordable” to the family of five that it has room for.  The car is slated to launch late next year in Japan, the United States, and Europe.
