Get this week's green tips from Rosario Dawson and Kiersten Warren. (Gerri Miller)


Rosario Dawson: Hi, I'm Rosario Dawson, and my green tip is: if you drive with your car empty and keep your tires filled at all times, you can save a tank of gas a year.

Kiersten Warren: I'm Kiersten Warren, and my green tip of the day is to stop buying so many clothes. Shop your closet before you go out and drop thousands on a dress that you'll wear one time. It just seems really unconscionable during this time. That's my tip.
