瑞士联合银行分析师Andreas Bokkenheuser称，除非消费者被迫为环境污染支付更多的费用，比如缴纳烟尘排放税，否则这不会有什么改变。

Andreas Bokkenheuser, an analyst at UBS, says little will change until consumers of coal are forced to pay more to pollute, via a carbon tax, for example.

通常采用征收庇古税的方法来解决环境污染的外部性问题，以弥补社会成本与私人成本的差额，但是不能与实际的减污效果相联系。

By collecting Pigou tax, the exterior problems of the environmental pollution are solved to compensate the gap between the public cost and the private cost.
