All seven policies have already been successfully implemented in countries around the world, but they need scaling up. While cap-and-trade systems or other means of pricing carbon emissions can help provide incentives for businesses to invest in low-carbon solutions, in the short term at least, these seven policy measures – and direct action and investment by governments – are needed to achieve the targets.
目前，所有的这七项政策都已经在全世界范围内成功地运用，但我们还需要进一步地推广。我们应该实行总量控制与交易制度，加上其他价格手段，迫使企业加大对低碳产品的投资。从短期来看，这七项由政府主导的政策将能实现我们设定的目标。
