He pays money to third world countries to protect the rain forest, and claims the rain forest he is protecting counters out the stuff from his jets and SUVs. Seriously. You cannot make this stuff up, it is too bizarre.
That's what I heard. He's taking the "trading credits" express (although "environmentalists" don't like it when industries do the same thing). Basically bribing people in the third world to take his money and say they are going to "do something" to reduce the carbon burden in the ecosphere, which somehow magically offsets exactly what Al and his entourage are putting out into the air jetting around on all those private planes telling the rest of us how decadent we are.
