The polluter pays principle would mean that those who are the biggest polluters will be the ones to pay the most. In the case of global warming, this would mean that the companies of the industrialised countries, particularly in the United States, will have to bear the biggest burden and, therefore, may be unable to compete in the global economy. The US position has nothing to do with saving the environment. It has to do with the saving of its own economy. This is no way to manage global resources.
Global resources have to be managed on the principle of equitable entitlements of all stakeholders.
