The fuel discount is economically unfair.
This speaks in favor of it
Wealthier households tend to benefit more: The discount was granted per liter of fuel. Therefore, those who fill up frequently receive a greater absolute saving. This is problematic from a distributional policy perspective because higher-income households spend significantly more on fuel on average.

While these people were also affected by general energy price inflation, they did not receive any direct benefit from the reduction in fuel tax.

Opportunity costs for the state: A tax cut means lower revenues. This money is then unavailable for other relief measures or public investments. The DIW estimated the cost of the fuel discount at around €3.15 billion. Therefore, the economically relevant question is not only: "How much money does a driver save?" but also: "What else could the state have done with those billions?"

Problematic ecological incentives: Lower petrol and diesel prices make driving relatively cheaper. This weakens the incentive to: drive less; form carpools; switch to buses and trains; and use a more fuel-efficient or electric vehicle. The fuel discount is therefore, at least in the short term, in conflict with climate policy goals.

Not every euro of the tax cut reaches consumers. A study found that 97–99% of the gasoline tax cut and 75–86% of the diesel tax cut were passed on to consumers.

Motorists are directly affected by an extraordinary price shock – a fuel discount can provide quick and uncomplicated relief. The Federal Ministry of Finance (BMF) explicitly described the measure as part of the relief package and combined it with other measures such as an energy allowance, a child bonus, and discounted public transport tickets.

The argument "Those with little money should simply drive less" doesn't work for everyone. For example, someone living in a rural area 30 or 50 km from their workplace may have: inadequate public transport, shift work, childcare responsibilities, or a workplace that is difficult to reach by bus and train. For such individuals, high fuel prices are difficult to avoid in the short term. Therefore, fuel discounts can be seen as a temporary measure to mitigate the impact of external price shocks.

Businesses were also affected: Fuel is not just a consumer good for private drivers. Companies need diesel and gasoline for purposes such as: - Transportation - Trades - Agriculture - Delivery services - Field service. Very high fuel prices can therefore lead to further price increases through higher transportation and production costs. A reduction in fuel tax could theoretically help to mitigate inflationary cost increases.

The fuel discount was quick to implement - direct, targeted transfers require administrative procedures and can therefore have a slower effect.
21.09.2026
The empirical effect was greater than partly expected: The later study by Bernhardt et al. concludes that the tax reduction actually lowered prices significantly: by about 33.8–34.4 cents per liter of gasoline and 12.2–14.6 cents per liter of diesel.

Households with a monthly net income of more than €5,000 spent on average about nine times as much on fuel as households with less than €1,300.

https://www.diw.de/de/diw_01.c.837251.de/%26In 2022, the German Federal Cartel Office observed an unusually large discrepancy between crude oil prices and prices at the refinery and gas station levels. It therefore launched an investigation. The interim report pointed, among other things, to shortages, structural problems in the refinery and wholesale markets, and the high degree of vertical integration among oil companies. At the same time, the Federal Cartel Office could not simply conclude that the oil companies had unlawfully retained the fuel rebate. => A tax cut does not guarantee that a market price will fall by precisely the same amount. How much a tax change is passed on depends, among other things, on supply, demand, and competitive conditions.

Several complementary approaches could be pursued in parallel: 1. Direct transfers to low-income households: + very targeted, - administrative costs 2. Mobility allowance for low-income commuters: + takes into account the particular burden of mobility, - defining the boundaries can be difficult 3. Increase in social benefits: + reaches those most in need, - not specifically aimed at mobility costs 4. Temporary commuter allowance/tax credit: + supports workers with long commutes, - low-income earners may benefit less 5. Expansion of public transport and affordable tickets: + less dependence on cars in the long term, - effect only in the medium to long term 6. Climate allowance/per capita refund: + can have a socially balancing effect, - design and financing are crucial 7. Targeted support for companies with high fuel dependence: + prevents certain production and transport problems, - difficult to define the boundaries Fuel discounts: quick and easy, not very targeted, and ecologically problematic

It's simply a loan from the current generation, which future generations will have to repay. Most citizens could have afforded the increased fuel consumption, perhaps even switching to bicycles or public transport. They have now received support, but this support will have to be recouped through tax revenue – eventually, when a debt brake is reinstated, and only if it's enforced for many years. This could take until the next generations.

Politics should focus on long-term relevant problems and intervene as little as possible in economic processes – especially when dealing with time-limited, non-strategic and difficult-to-assess challenges that are to be regulated by intervention.
