Climate change is a global commons problem.

It does not cost the world to save the planet.

First of all, developed countries have basically expropriated the atmosphere of the world community. But one must say clearly that we redistribute de facto the world's wealth by climate policy.

This has almost nothing to do with environmental policy anymore.
