Macron urges EU to loosen oil product rules as France faces diesel crisis

France is running low on diesel, and Emmanuel Macron has decided the paperwork is part of the problem. The French president sent a letter to European Commission President Ursula von der Leyen on September 18, 2026, requesting that Brussels temporarily ease EU fuel quality specifications and push back a methane emissions reporting deadline by a full year.

The letter lands at a genuinely difficult moment. Diesel prices in France have climbed to €2.39 per liter, and between 14% and 16% of the country’s filling stations were reporting shortages of at least one fuel type in mid-to-late September 2026.

What Macron is actually asking for

The proposed regulatory adjustments are technical but consequential. Macron’s letter calls for loosening thresholds on fuel density, volatility, and desulfurization, while also permitting an increase in biodiesel blending from the current B7 standard to B10, meaning up to 10% of diesel could come from biological sources rather than crude oil.

French refiners estimate these changes alone could lift domestic production by somewhere between 5% and 20%.

On the methane side, Macron is asking to push the compliance deadline for emissions monitoring obligations, adopted in 2024, from January 1, 2027, to January 1, 2028. The argument is straightforward: oil and gas importers face meaningful legal exposure if they cannot verify methane data from suppliers in regions currently experiencing disruption, and a one-year extension would allow the market to stabilize before enforcement kicks in.

Neither ask is a permanent rollback of environmental policy. Macron has framed both requests as emergency measures, analogous to the temporary exemptions the EU granted energy companies during the COVID-19 pandemic.

Why the supply crunch is this bad

Europe now sources 36% of its kerosene and 18% of its diesel from the Middle East. Supply disruptions in the region, ongoing since early 2026, have tightened those flows considerably.

Refiners cannot sign long-term import contracts with confidence when the source geography is unstable, so they are running leaner inventories. Leaner inventories mean less buffer when demand spikes or a delivery is delayed.

What Brussels does next

The European Commission has not yet publicly responded to Macron’s letter. If the Commission agrees to even a partial version of the French proposal, European refiners could move relatively quickly to adjust blending ratios and processing parameters. The 5-20% production uplift estimate is a wide range, reflecting genuine uncertainty about how individual refineries would respond, but even the lower end of that band would meaningfully ease the pressure on French filling stations.
