EU Carbon Markets Enter a Political Summer

On 17 July 2026, the European Commission is due to publish its long-awaited overhaul of the EU Emissions Trading System (ETS). Reporting ahead of the proposal points in a clear direction: slower emissions cuts, more free allowances for industry, and a softer glide path for sectors exposed to international competition. For a market that has spent years pricing in ever-tightening supply, that is a meaningful shift in tone — and a live variable for anyone whose costs move with the EU Allowance (EUA) price.

What is being debated

The revision is meant to align the ETS with the EU's newly adopted 90%-by-2040 emissions target, while answering a louder complaint from member states and industry: that the current scheme is hurting European competitiveness in a difficult geopolitical environment.

Several concrete changes are reported to be on the table. The Commission is expected to propose a lower "linear reduction factor", the rate at which the emissions cap shrinks each year, currently 4.3% and set to rise to 4.4% from 2028, which would slow the tightening of allowance supply. Industry could receive additional free allowances, with reports suggesting a package worth as much as €6 billion, in exchange for decarbonisation investment. And Brussels is reportedly looking at ways to extend free allocation for sectors covered by the Carbon Border Adjustment Mechanism (CBAM) beyond the previously planned 2034 phase-out. The centre-right EPP has been pushing in the same direction, framing the debate around industrial competitiveness.

Running alongside all of this is ETS2, the separate system covering emissions from road transport and buildings upstream at the fuel-supplier level. It is set to become fully operational in 2028, with a cap designed to cut covered emissions by 42% by 2030 versus 2005, and mechanisms to smooth the launch. Its revenues are earmarked for climate and social measures.

Why this matters for power, industry and procurement

The carbon price is not a niche concern, it sits inside the cost of every fossil-fuelled megawatt-hour. When gas or coal plants set the marginal price (which they still frequently do), the EUA cost passes straight through into wholesale power. So the ETS debate is a power-price debate, not only an industrial-policy one.

For energy-intensive industry, free allocation is the difference between a manageable carbon bill and an existential one, which is why the free-allowance and CBAM questions are being fought so hard. For power buyers, the read-across is subtler: anything that changes the expected trajectory of the carbon price changes the expected trajectory of forward power, all else equal.

And ETS2 widens the perimeter. From 2028, organisations with significant transport fuel or building heating consumption will face a carbon cost they do not directly pay today, passed through by fuel suppliers rather than billed to installations.

Why it matters for energy buyers

The honest summary is that policy direction and price direction are not the same thing. A lower linear reduction factor and more free allowances loosen supply, which, in isolation, is bearish for EUAs. But carbon markets also price expectations, credibility and long-term scarcity. If the market reads the reform as a durable softening of ambition, that points one way; if it reads it as a temporary competitiveness cushion inside an unchanged 2040 target, sentiment may prove stickier. Both readings are plausible, and the detail of the 17 July text will matter more than the headlines.

What buyers should monitor

Watch the actual proposal on 17 July, in particular the numbers on the linear reduction factor, the size and conditions of any free-allowance package, and the CBAM timeline. Then watch the political reaction — Parliament and Council can reshape a Commission proposal substantially, so the first text is a starting point, not a settled outcome. For 2028 planning, map your exposure to ETS2 now: transport fuel and building heating volumes that sit outside today's ETS but will carry a carbon cost tomorrow.

For years the ETS story was one of steadily rising ambition and tightening supply. This summer it becomes a genuinely political market, where competitiveness and climate goals are being openly renegotiated. That does not automatically mean cheaper carbon, but it does mean more policy-driven uncertainty in a price that flows straight through to power. The 17 July proposal is where that uncertainty starts to resolve.
