I think you missed the point of my post. My point was that consumers produce 22% of pollution directly, and 78% indirectly.

Suppose I contribute 22 tons of pollution by driving my car, and GM contributes 78 tons of pollution building the car. Therefore, if I don't buy the car, pollution only drops by 22 tons!

This analysis ignores the fact that if I won't buy a car, GM won't build it (reducing pollution by 100 tons).
