The report also sheds light on another important question in the climate debate: Is global cooperation critical to mitigate climate change? For a given economy, does acting alone yield distinctly inferior growth paths – say, by damaging the competitiveness of its tradable sector?
报告还提出了气候争论中的另一个重要问题：全球合作对遏制气候变化是否关键？对于给定经济体，单独行动是否会导致显著更劣的增长路径——比如破坏可贸易部门的竞争力？如果答案是肯定的，那么国际政策合作就似乎是遏制气候变化方面进步的必要前提。
