There are no subsidies, gas and diesel are the most expensive in the world, and most of the cost is taxes. But apparently, for the EU politicians, that is still too cheap, so they want even more taxes on top of that.
You are thinking too logically. In EU fuel is expensive because it’s heavily taxed AND there are a lot of fuel subsidies.
Or to quote an old TV show: Hacker: One of your officials pays farmers to produce surplus food, while on the same floor, the next office is paying them to destroy the surpluses. Maurice: That is not true! Hacker: No? Maurice: He is not in the next office, not even on the same floor!
In 2021 Europe provided $135 Billion in subsidies to the petroleum industry. A net increase of about 30% from 2015.
