The Clinton Administration released an economic analysis in July 1998, prepared by the Council of Economic Advisors, which concluded that with emissions trading among the annex B/annex I countries, and participation of key developing countries in the "Clean Development Mechanism"—which grants the latter business-as-usual emissions rates through 2012—the costs of implementing the Kyoto Protocol could be reduced as much as 60% from many estimates.
Clintonova vláda vydala v júli 1998 ekonomickú analýzu, spracovanú Radou ekonomických poradcov (Council of Economic Advisors), ktorej záverom bolo, že obchod s emisiami s krajinami v Prílohe B/Prílohy I. a zúčastnenie sa s spolu s vyspelými krajinami na „ Mechanizme čistého rozvoja“, by podľa mnohých odhadov zredukovalo náklady na uskutočnenie opatrení Kjótskeho protokolu na 60 %.
