The Industrial Accelerator Act that the Commission adopted on 4 March is, on its face, an industrial policy file. Read more carefully, it is a procurement directive in disguise. The proposal would introduce mandatory low-carbon and Union-origin thresholds into above-threshold public tenders for a defined set of strategic products. The mechanism is unusual enough that contracting authorities and industrial buyers are only now beginning to translate the regulation into purchasing terms. Compliance starts in 2029, but the procurement frameworks the rules will modify are already being signed today.
The strategic perimeter covers steel, cement, aluminium, batteries, solar photovoltaics, heat pumps, wind technology and nuclear. For energy-intensive materials, the thresholds bite immediately. At least 25 percent of total steel volume in scope contracts must qualify as low-carbon. At least 25 percent of aluminium must be both low-carbon and of Union origin. For concrete and mortar, the dual requirement applies to 5 percent of total volume. These percentages look modest, but they apply to the entire structural envelope of public works in strategic sectors, and the certification chain required to evidence them does not yet exist at scale.
The Union-origin question is where the legal architecture gets interesting. Content from countries with a free trade agreement or a customs union with the Union, and from parties to the World Trade Organization Government Procurement Agreement, is treated as equivalent to EU content. That carve-out is large. It includes the United Kingdom, Norway, Switzerland, South Korea, Japan, Canada and a long list of GPA signatories. The exemption is intended to keep the regulation defensible against a WTO challenge. It also dilutes the headline reading of “Made in EU”. The instrument is closer to a low-carbon trade-policy-compliant procurement filter than to a true domestic-content rule.
Industry response has split along predictable lines. Energy-intensive producers welcome the demand-side anchor because it gives low-carbon capital projects a procurement backstop they currently lack under the Carbon Border Adjustment Mechanism alone. Construction federations have been more cautious. They argue that the certification overhead for cement and concrete will land on small subcontractors who will need to invest in environmental product declarations and chain-of-custody documentation that are not yet harmonised across Member States. Without a single Union template for the supporting evidence, the same project could be compliant in one capital and ambiguous in another.
There is a quieter competitiveness debate sitting underneath this. The 25-percent figure for low-carbon steel is calibrated to the supply that European mills can plausibly deliver by 2029, given the current Direct Reduced Iron and electric-arc capacity investment pipeline. The aluminium figure is more strained. Union primary aluminium output has been falling since the 2022 energy shock, and the requirement that the 25-percent volume be both low-carbon and Union-origin places a structural demand on a sector that is still working out whether to reinvest in domestic smelters or to convert to recycling. The procurement floor may end up acting as an investment signal in its own right.
For contracting authorities, the practical question is how to write the threshold into tender documents now, before the detailed implementing acts arrive. The Commission has signalled that secondary legislation will define the calculation methodology, the eligible certification schemes and the audit mechanism. Until those land, buyers face a choice between writing the regulation’s text into specifications verbatim and inserting flexibility clauses that allow updates as the detail clears. Several large infrastructure ministries have already opted for the second approach, which suggests the implementing acts will matter at least as much as the framework itself.
The deeper effect of the file may sit outside its strategic-product list. Once the European public sector has a working template for low-carbon and origin-conditional procurement, the same approach will be much harder to keep out of other sectoral procurement frameworks. Healthcare, defence and transport buyers have already raised the question internally. The Industrial Accelerator Act may turn out to be less a single instrument than the start of a procurement doctrine, and the value of the 2029 deadline is the time it gives capitals and contracting authorities to work out where that doctrine ends.
