Edward Norton

This leading man has been leading the way for green celebs since 2003, when he helped create the BP Solar Neighbors Program. Each time a celeb has a solar electricity system installed on their house, BP donates a system to low-income family. Norton was the first to do it — he thought it up, when having solar installed on his home.He also has convinced other big names like Will Ferrell, Robin Williams, and Tom Hanks to do it; fellow list-mates Brad Pitt, Ed Begley Jr., Jack Johnson, and Daryl Hannah are also proudly on the list. A great example of how celebs doing good helps everybody win.
