摘要

1.USA is a net gainer in net present value terms from unilateral implementation;2.The comparative net benefits to Europe and China are negative but small, making their choice sensitive to the discount rate and temperature scenario;3.The dominant strategy for all other countries is to free ride;4.Taking the three large economies as a group, there are net gains from abatement that would be bolstered by universal adoption;5.Yet compensatory side payments are still not affordable. The net gains to all regions do not begin to appear for two decades, rendering commitment to abatement politically difficult.
