In the long run, success will require major technological advances and their broad adoption. As these are still unknown today, the initial challenge will be to jump-start the mitigation and learning processes, and create powerful incentives for technology that will increase energy efficiency and reduce CO2 emissions in the long run.
换言之，我们应当关注短期措施，比如说今后15年的变化。从长远来看，取得成功需要重大的技术进步和对先进技术的普遍应用。因为这在今天还无法预测，因此从长远来看的首要挑战在于启动减排和学习过程，并能有效刺激提高能源效率的技术，同时降低二氧化碳排放。
