There's a whole bunch of different proposals for what should happen. The UN agreed that we should consider a peak and decline from 10 to 15 years and be well below 50% of global emissions by 2050, and that has very real implications for the developing world. Both of those things mean that the developing world, during that 10- to 15-year period, will have to peak and decline themselves, because they're making up an increasingly large proportion of the emissions. As I said, developing countries have signed onto that in Bali, saying that we do need that peak and decline to happen.
