There has been a recent bump in the number of blog entries highlighting which celebrities are green and which are not. But Treehugger ups the ante a bit: Instead of showing the different levels of environmental awareness among celebrities, they point out how widely-regarded "green" celebs aren't really as polluter-proof as they claim to be. So next time you see stars on TV speak out for the environment--or speaking against polluters--remember that even they aren't invincible to their own pollution.
