Following a review of the alternative architectures for the next Climate Change Agreement, the paper outlines four areas in which trade will play a role: as a purveyor of technological transfer; as a mechanism to separate where abatement takes place from who bears the cots of abatement; as a participation mechanism; and as a way to address the pressures for border adjustments. Political-economy considerations are invoked to predict that a target system with a carbon credit system will be preferable to a carbon tax or to a portfolio system of treaties. A review of evidence on the extent of pollution haven effects suggests that these should be small under climate mitigation policies, especially if efforts are undertaken to raise the price of energy. A discussion of border measures to complement mitigation policies suggests that they are unlikely to be found compatible with the environmental exceptions allowed under article XX of the GATT. The review concludes that an umbrella agreement with leeway where much initial mitigation would first take place unilaterally as under the early days of the GATT might be the most promising way ahead while preserving an open World Trading System and environmental integrity.

; de Melo, JaimeA growth-decomposition (scale, technique and composition effect) covering 62 countries and 7 manufacturing sectors over the 1990-2000 period shows that trade, through reallocations of activities across countries, has contributed to a 2-3 percent decrease in world SO2 emissions. However, when compared to a constructed counterfactual no-trade benchmark, depending on the base year, trade would have contributed to a 3-10 percent increase in emissions. Finally adding emissions coming from trade-related transport activities, global emissions are increased through trade by 16 percent in 1990 and 13 percent in 2000, the decline being largely attributable to a shift of dirty activities towards cleaner countries.
