The G-7 countries should clearly signal that they are serious about the low-carbon transition, and the most effective way to do that would be to support a global goal of cutting net greenhouse-gas emissions to zero by 2050. In addition, governments and regulators can take concrete steps to stimulate private-sector investment in cleaner forms of energy.
G-7国家应该释放明确信号表明它们将严肃对待低碳转型，而这样做最有效的办法是支持到2050年将温室气体净排放量削减到零的全球目标。此外，政府和监管者可以采取务实举措刺激私人部门投资于更加清洁的能源形式。
