1.Although Mr Bush is not yet ready to contemplate a binding international treaty that would limit greenhouse-gas emissions, he does advocate policies that could help trim America's emissions. As it is, states representing over half of America's emissions have pledged cuts of some kind. Congress, meanwhile, is contemplating several bills that would impose a national cap. Australia, the other rich country that rejected Kyoto, is also working on an emissions-reduction plan.
2.All this hints at the shape of things to come. America and Australia can probably be enticed to limit emissions, especially if, as expected, both get new governments in the next year or two. But the oversight and administration of such a deal might be looser than under Kyoto, given America's suspicion of global bureaucrats.
