摘要

The aim of Phase 2 of the United Nations Environment Programme was to develop consistent guidelines for estimating costs of limiting greenhouse gas emissions and to build up a capacity for their use in developing countries. Brazil, India, Egypt, Thailand, Senegal, Venezuela, Zimbabwe, Denmark, France and the Netherlands were dealt with. Most of these countries expect primary energy consumption to grow more slowly than the Gross Domestic Product so that energy/GDP intensity decreases. Conversely, especially in Brazil and Thailand but not in France or Denmark an increasing intensity of CO(sub 2) intensity of primary consumption in the baseline is expected. Overall, by years 2020/30, CO(sub 2) emissions would be reduced to 2100 million tons corresponding to a 40% reduction in CO(sub 2) from baseline but a tripling of emissions. Country teams estimated abatement cost options for reduction targets from baseline between 12.5-25% in 2005/10 and 30-35% in 2020/30. Cost curves for developing countries exhibit a significant potential for negative cost abatement options, with the exception of Venezuela. The Danish study indicates a substantial negative-cost potential whilst that of both France and the Netherlands is much higher. Achieving short-term and long term targets will result in total annual costs of less than 0.7%. Total abatement costs would be negative for Brazil and Denmark in the short-term and Egypt and Senegal in the long term. In the long-term, average abatement costs for reduction from baseline between 25% and 50% range between 5-37 dollars per ton CO(sub 2). Only France lies outside this range. (AB) (42 refs.)
