The G-20 countries, which have already agreed, in principle, to phase out fossil-fuel subsidies, should seize the moment. They could hold a “side-summit” in Warsaw at which they set a schedule for translating principle into practice.
G-20国家已经在原则上同意逐步取消化石燃料补贴，它们应该抓住这个机会。它们可以在华沙举办一个“方面峰会”，为将原则落实为政策设定时间表。目标应该是到2020年全部取消化石燃料补贴。
