Clean Power Earns Nothing Where It Is Used Most

Europe charges importers for the carbon that went into making a product. It does not charge them for the carbon in their electricity, so long as what they make is aluminium, steel or hydrogen.

Those are among the industries where electricity matters most. Power is the largest line on a smelter's cost sheet. Cement and fertiliser use a fraction as much, and their electricity is counted.

So a smelter can move its entire supply to wind and solar and owe exactly the same charge as before. A cement plant doing the same thing can reduce what it owes.

That is worth sitting with, because it is the reverse of what almost everyone assumes. The carbon rule is expected to reward lower carbon production. It does, in the places where power barely matters, and not at all in the places where it decides the economics.

Why the exemption exists

Not an oversight. European producers of these goods already receive state support that reimburses them for the carbon buried in their electricity bills. If Europe also charged importers for that same carbon, importers would be paying for something domestic producers get refunded.

So the exemption is a mirror. It is there because of something happening on the European side of the border, and it says nothing about your plant.

Which is why it will not last

A borrowed exemption ends when the thing it was borrowed from changes. The regulation says so outright: if Europe revises how it compensates its own producers, the scope of the border charge should follow.

That has already been tested once. The Commission was required to decide, before the end of 2025, whether to start counting electricity in these industries. The answer came in December. It expanded the charge in other directions, left electricity alone, and promised another look in 2027.

The review that could have ended the exemption has already happened. The answer was not yet, ask again in 2027.

So this is not a permanent exemption. It is an exposure with a date on it. And power contracts run ten and fifteen years, which means most of them are being signed across that date.

What it would take to qualify

Here is the part that costs money later.

If electricity starts counting, the standard your supply has to meet is already written, because it already applies to cement and fertiliser. To get credit for clean power you need it from a named generating plant, physically delivered over a connection you can document, metered at both ends, with generation and delivery matched inside the same hour.

Read that against an ordinary long-term power deal and the gap is not small. Annual certificates do not qualify. Green tariffs do not qualify. A contract settled financially, where no electron reaches your site, does not qualify. Those instruments move a number in a sustainability report. Against this charge they are worth nothing.

Which is the whole point. Buying hour-matched physical power today, to reduce a charge that ignores your electricity, is paying for something the rule will not repay. What you want is the right to convert to it, and the cheapest time to negotiate that right is before the contract is signed.

Seven clauses

1. Hourly meter data, kept and auditable. The test works in hourly blocks at both ends. If the meters are not installed and the readings are not retained, nothing you draft later recovers the years already run.

2. Name the plant. Not a portfolio, not a blend. If your site draws on several sources, you get pushed back to a national average. And check the seller can document a physical connection between their plant and yours, because some cannot at any price. That is a choice of counterparty, made before anyone starts drafting.

3. A carbon limit on the supply, with a duty on the seller to replace anything that breaches it. There is a second, stricter version of this test that applies elsewhere in the rule, and it carries an emissions cap. This clause is insurance against that version being the one that arrives. It is not a requirement today.

4. The right to move from annual to hourly matching, at a price fixed now. This is the clause the others exist to support. Almost nothing signed today is hour-matched, and hourly matching is the expensive half. Agreeing the conversion price now turns a rule change into an exercise rather than a renegotiation you enter from a weak position.

5. Clean attributes transfer to you whatever the rules end up calling them. The carbon charge, disclosure standards and procurement rules all define clean power differently, and the definitions are still moving. Wording tied to today's labels will not last the contract.

6. The seller has to help you qualify later. You carry the burden of proof, but the evidence sits with them: their generation data, their grid documentation. A seller with no obligation can decline politely for fifteen years, and there is nowhere else to get it.

7. One contract, not a chain. If supply runs through a trader or a utility, the rule wants proof that a single contract binds all three parties. A back-to-back structure fails even when the plant is named correctly, and unpicking it later means reopening the commercial deal.

The option isn't bought, it's drafted.

Methodology

The rules are in Regulation (EU) 2023/956, published in the Official Journal on 16 May 2023, read directly rather than through summaries.

The split between counted and uncounted electricity is Article 7(1) and Annex II. Annex II covers iron and steel, aluminium, and hydrogen. Cement and fertiliser are absent from it, which is why their electricity counts. The Commission's own default value tables, in Implementing Regulation (EU) 2025/2621, show the same thing without interpretation: the indirect emissions column carries a value for grey Portland cement and reads N/A on every row of the direct-only goods.

The reason for the exemption, and the statement that it moves when European compensation moves, are in recital 22. The review obligation is Article 30(2), dated by the transitional period in Article 32. The answer to that review is the Commission's amendment proposal of 17 December 2025, which extends the charge to around 180 downstream steel and aluminium goods from 1 January 2028 and leaves indirect emissions where they are.

The qualification standard in the last two sections is Annex IV point 6 of the regulation together with Annex II point D.4.3 of Implementing Regulation (EU) 2025/2547 of 10 December 2025. This matters, because point 6 read on its own looks like a simple annual volume test. The implementing rules are where the hourly and physical conditions are set, and the two have to be read together. The stricter version referred to in clause 3 is point 5 of the same annex, which governs imported electricity and carries a cap of 550 grammes of CO2 per kilowatt-hour.

One caution on dates. Two separate things fall due in 2027. The review of whether to count electricity in these industries is the one discussed here. A revision of the default value tables is a different exercise under a different instrument, and the two are easily confused.

No price is claimed for what a clean megawatt-hour is worth against this charge. Where the charge does land, the ceiling is the grid emission factor times the certificate price, and it is a budget rather than a target. That arithmetic needs a grid factor and an electricity intensity per tonne, each with its own source, and it is not carried here.
