出于这一原因，许多经济学家赞同一项统一（协调）的全球税收来对世界上所有地方、所有来源的碳排放平等征税，无论来源是煤炭、石油或者天然气，无论消费者还是商家所排放。
For this reason, a wide range of economists favor a uniform (“harmonized”) global tax that would tax carbon emissions equally everywhere in the world, and from whatever source – whether coal, oil, or gas, and whether consumers or businesses.
