Capital, and by relation the system that centers the idea of Capital as a method for moving around resources is at the very center of this.
Since Capital follows near-term incentive, if the "pollute the world" path has a greater near-term incentive, that's where the market will follow. If a single member of the system goes for long-term incentive(not cooking the earth), other near-term incentive chasers will eat their lunch and remove a player.
The system itself is a tight feedback loop searching for local maxima, and the local max is often the most destructive. With chasing the local maxima, also comes profit and capital that influence the political system.
