Joe Stiglitz has a book forthcoming in September titled Making Globalization Work.

And he wants to involve the WTO in fighting global warming:

Not paying the cost of damage to the environment is a subsidy, just as not paying the full costs of workers would be… There is a simple remedy: other countries should prohibit the importation of American goods produced using energy intensive technologies, or, at the very least, impose a high tax on them, to offset the subsidy that those goods currently are receiving… Japan, Europe, and the other signatories of Kyoto should immediately bring a WTO case charging unfair subsidization.

Surely this can’t be the optimal policy tool to address the problem.
