	abstract = {This paper offers a detailed plan to set quantitative national limits on emissions of greenhouse gases, building on the foundation of the Kyoto Protocol. It attempts to fill in the most serious gaps: the absence of targets extending as far as 2100, the absence of participation by the United States and developing countries, and the absence of reason to think that countries will abide by commitments. The plan elaborates on the idea of a framework of formulas that can assign quantitative limits across countries, one budget period at a time. Unlike other proposals for century-long paths of emission targets that are based purely on science (concentration goals) or economics (cost-benefit optimization), this plan is based partly on politics. Three political constraints are particularly important. (1) Developing countries are not asked to bear any cost in the early years. (2) Thereafter, they are not asked to make any sacrifice that is different in kind or degree than was made by those countries that went before them, with due allowance for differences in incomes. (3) No country will accept an ex ante target that costs it more than 1\% of GDP in present value, or more than 5\% of {GDP} in any single budget period, or will abide by it ex post. An announced target path that implies a future violation of these constraints will not be credible, and thus will not provide the necessary signals to firms today. Thus paper tries out specific values for the parameters in the formulas (parameters that govern the extent of progressivity and equity, and the speed with which latecomers must eventually catch up). The resulting target paths for emissions are run through the WITCH model. The outcome is reasonable, in terms of both carbon abatement and economic cost, even though the targets obey the political constraints.},
