After all, one of the major arguments against a “carbon tax” has been that it would make energy more expensive. Even assurances that the revenue from such a tax would be refunded to taxpayers were inadequate to overcome political resistance, particularly in the US.
但是，油价的急剧下跌确实提供了千载难逢的政治集会引入更多的碳定价。毕竟，反对“碳税”的一大理由是这会让能源变得更加昂贵。即使保证这一税种的收入将用于向纳税人返利，但这仍不足以克服政治反对，特别是在美国。
