Because crude oil is priced in US dollars, and the dollar has depreciated against the euro, European consumers have gotten off relatively easy from rising energy prices. So an energy tax roughly equal to the euro’s 33% appreciation in recent years would be about right.
由于原油是以美元来标价，而美元相对欧元已经贬值，欧洲消费者在能源涨价中相对得以脱身。所以，大致相对与欧元近年来升值33%的能源税大体上是正确的。
