Spain Subsidizes Diesel, Not Gasoline: Government Logic

Diesel Discounted, Gasoline Excluded: The Government's Ecological Paradox

The Spanish government applies a €0.20 per liter discount to diesel but excludes gasoline, the fuel that emits fewer nitrogen oxides and particulates in urban areas. Presented as relief for the transport sector, the measure clashes with official climate narratives: it subsidizes the fuel most harmful to urban health while ignoring the one contributing most to global warming. Another paradox for the collection.

An Automatic Discount, Not a Green Decision

This is not environmentalism: the discount responds to a decree approved in June that activates bonuses when a fuel's price rises by more than 15%. Diesel exceeded this threshold by just 0.7%; gasoline, with an increase less than half that amount, was left out. It is a mechanism to prevent freight transport, agriculture, fishing, and industry from driving up inflation. Diesel is the lifeblood of the system: without it, the country stops.

Emissions: Diesel vs. Gasoline, the Paradox

The data is stubborn: diesel consumes less and emits less CO₂, but expels more nitrogen oxides and soot. Gasoline releases more CO₂, but its local emissions are less toxic. In cities, gasoline wins. And here comes the historical anecdote: twenty years ago, diesel was the fuel meant to save the planet from the devil gasoline. Today, it is the demon. The ideological pendulum also pollutes. Modern diesel engines (post-2016) have significantly reduced emissions, but at the cost of such complex mechanics that many fail before reaching 100,000 kilometers.

Real Price: Taxes, Pensions, and Elections

Half of what we pay at the pump is taxes. The discount is temporary makeup: what isn't paid now will be paid later via taxes, with interest. Some analyses suggest the measure aims to contain CPI to avoid adding €10 billion to the cost of pension revaluation during an election year. Others recall that the last discount lasted less than three days and prices returned to nearly €2. The question is whether this exception will become the norm or if, as always, we will end up paying the bill.
