It is the most controversial proposal of the European Commission’s „Fit for 55“ climate package: the introduction of a separate EU emissions trading system for carbon emissions from buildings and road vehicles (ETS 2). No wonder: To be able to also achieve the stricter EU climate targets in these sectors, ETS 2 would make fossil fuels and heating fuels more expensive. In the future, consumers would see directly at the gas pump and in their heating bills that climate protection has its price. This is always unpopular, and especially in times of rapidly rising inflation, it would hit people with lower and middle incomes particularly hard.
