The European Union’s carbon market was supposed to be the "cornerstone" of its green transition, a rigid mechanism designed to make pollution expensive enough to force change. But theory usually survives only until it meets a crisis. Right now, with the Iran war choking off global energy supplies and sending electricity costs through the roof, Brussels is facing a cold reality. They can’t just watch as their industrial base collapses under the weight of both high gas prices and high carbon costs.
For months, the European Commission held the line. They told manufacturers to "stay the course" and insisted that the Emissions Trading System (ETS) was working as intended. But as oil sits stubbornly above $110 a barrel and the Strait of Hormuz remains a high-risk gamble for LNG tankers, the tone has shifted. We're now seeing the first real signs that Brussels is preparing to pull the "carbon price brake."
The double squeeze on European industry
If you’re running a steel mill in Germany or an aluminium smelter in France, the last few weeks have been a nightmare. It's not just that your energy bills have doubled; it's that you're getting hit from both sides. When gas prices spike, coal-fired power plants often ramp up to fill the gap. Because coal is more carbon-intensive, these plants need more ETS allowances. This drives up the price of carbon, which then gets baked right back into your electricity bill.
It's a feedback loop that basically punishes companies for an energy crisis they didn't create. The price of European gas (Dutch TTF) has already jumped over 50% since the conflict began in late February 2026. In Italy, where the grid relies heavily on gas, electricity prices are hitting levels that make domestic production almost impossible.
Industry groups aren't just complaining; they're warning of "industrial demand destruction." That's a polite way of saying factories are shutting down and they might not ever turn the lights back on. European Aluminium recently noted that the continent has already lost about 50% of its primary production capacity since the previous energy crisis in 2022. They can't afford another round.
How the carbon price brake actually works
So, how does the EU actually stop the bleeding without trashing its climate goals? The mechanism everyone is whispering about is Article 29a of the ETS Directive.
Essentially, this is the "emergency exit" for the carbon market. Under the current rules, if carbon prices are more than three times the average of the previous two years for six consecutive months, the Commission has to act. The problem? Those rules are way too slow for a wartime economy. Waiting six months to see if a price spike is "permanent" is a luxury European manufacturers don't have in 2026.
Here is what is actually being discussed behind closed doors in Brussels:
- Adjusting the Trigger: There is massive pressure to lower the "three times average" threshold. Critics argue that even a 50% jump in carbon prices during an energy crisis is enough to sink a company.
- Releasing the Reserves: The EU has a "Market Stability Reserve" (MSR)—a literal vault of unused carbon permits. By releasing these into the market, Brussels can artificially increase supply and force the price down.
- Free Allocation Pauses: For "hard-to-abate" sectors like cement and chemicals, the EU was planning to phase out free carbon permits as the new Carbon Border Adjustment Mechanism (CBAM) kicked in. There’s now a serious move to delay this phase-out to give companies some breathing room.
The political divide in the Berlaymont
Don't think this is a done deal yet. There’s a fierce internal fight going on. On one side, you have the "Climate Purists" who believe any intervention undermines the market's credibility. They argue that if you lower the carbon price now, you're just subsidizing fossil fuels and slowing down the shift to renewables.
On the other side, you have the "Industrial Realists." This group, led by countries like Italy and parts of the German coalition, argues that there's no "green transition" if there's no industry left to transition. They're looking at the massive subsidies in the U.S. and China and realizing that Europe is becoming an industrial museum.
Honestly, the "purist" argument feels increasingly out of touch. If a factory in Poland shuts down because of high carbon costs, it doesn't stop polluting; it just moves to a country with lower standards. That’s "carbon leakage," and it’s the exact thing the ETS was supposed to prevent.
What this means for the 2026 Review
The timing of the Iran war is particularly awkward because 2026 was already the scheduled year for a massive "health check" of the ETS. The European Commission is currently conducting a review to decide how the market should look through 2030 and beyond.
Before the war, the focus was on making the cap even tighter. Now, the conversation is all about "flexibility" and "resilience." We're likely to see a proposal by July 2026 that includes a much more responsive Article 29a. Expect a mechanism that can be triggered in weeks, not months, based on energy price volatility rather than just a long-term carbon average.
Practical steps for businesses navigating the volatility
If you're managing industrial operations or energy procurement, you can't wait for Brussels to fix the market. The carbon price brake will help, but it won't bring back the "cheap energy" era.
- Hedge your carbon exposure now: If the EU does intervene, prices will dip, but only temporarily. The long-term trajectory for carbon is still up. Use any policy-driven price drops as a window to secure allowances for the next two years.
- Audit your CBAM readiness: The border tax is still happening. Even if free allowances are extended, the administrative burden of CBAM is landing this year. Ensure your supply chain data is clean so you don't get hit with "failure to report" fines on top of high energy costs.
- Pressure for "Indirect Cost Compensation": Some member states allow companies to get refunds on the carbon costs hidden in their electricity bills. If your country doesn't do this, now is the time for your trade association to be in the ear of your national energy ministry.
The Iran war has proven that Europe’s energy security and its climate policy are the same thing. Brussels is finally realizing that a "perfect" carbon market is useless if the people using it are out of business.
