摘要: Following the Copenhagen climate Accord, developed and developing countries have pledged to cut their greenhouse gas emissions, emissions intensity or relative baseline. This analysis puts targets for major on a common footing, compares them across different metrics. Targeted changes in absolute differ markedly between countries, with continued strong increases some but significant decreases others including Indonesia, Brazil South Africa, provided reasonable baseline projections are used. Differences smaller when expressed per capita terms. Reductions of economies implicit remarkably similar China's target spanning almost same range as reductions United States, EU, Japan, Australia Canada. deviations from business-as-usual also majority total global baselines may originate China other countries. The findings suggest that most broadly compatible important metrics, while overall ambition falls short two degree trajectory, by key can be considered commensurate context what pledged.
