The Tesla is not Damon's first green vehicle. Back in 2005, Damon bought a hybrid car. The movie star also co-founded H2O Africa, a foundation that finances sanitation and clean-water projects in Africa. And last year, Damon tried to green the globe by joining an online organization that attempts to prevent trees from being cut down and used for junk mail.
