A high-stakes bet on a scarce resource: What if the future of Europe's auto industry depended on a material that barely exists? That is the gamble at the heart of the European Union's new Industrial Accelerator Act, unveiled on March 4, 2026. Under the plan, automakers must cut tailpipe CO₂ emissions by 90% by 2035. The remaining 10% can be compensated for, but not just by any means. The EU is mandating that a portion of this compensation come from using low-carbon "green steel" made in Europe, a product that is currently scarce, expensive, and lacks a clear definition.

How the Automotive Package Works

The EU's strategy, embedded within the Industrial Accelerator Act, creates a new flexibility mechanism for automakers facing the 2035 CO₂ reduction targets. While the headline goal remains a 90% cut in "tailpipe" emissions, the remaining 10% can be offset through a combination of two specific methods:

Offset MethodAllowed Contribution
CO₂-reduced steel (EU-made)Up to 7%
E-fuels & renewable fuelsUp to 3%

This means that in practice, vehicles with internal combustion engines, including plug-in hybrids (PHEVs), range extenders, and mild hybrids, could still be sold after 2035, provided their manufacturers can secure enough certified green steel to balance their fleet emissions.

The Definition 'Wild West'

"Wild west" — one steel executive described today's market for green steel, with companies using varying terms, metrics, and thresholds to market their lower-emission products.

The lack of a standardized definition for "green" or "low-carbon" steel is a major stumbling block. In the days leading up to the Act's release, reports emerged that the European Commission had scrapped plans for a specific emissions label for steel, which would have provided this much-needed clarity.

An EU official cited concerns that the label would increase bureaucracy, especially as another product-labeling law is already being drafted. Eurofer, the European steel association, warned that delaying the label "risks pushing decisions back in time at a moment when investors are looking for certainty."

The Supply Problem: Too Little, Too Late

Even if a definition existed, the physical supply of green steel is a critical issue. Planned annual green steel capacity globally is projected to reach around 28 million tons by 2050. However, Reuters calculations show that only a third of that capacity is actually under construction.

European capacity: Around 18 million tons of planned capacity would be in Europe, but major projects from companies like Thyssenkrupp and ArcelorMittal have faced delays, pauses, or cancellations. ArcelorMittal's CFO, Genuino Christino, admitted: "We don't really have hydrogen available—at least not in the scale needed."

The cost of green hydrogen, a key input for the most ambitious low-carbon steel production routes, remains prohibitively high. When the steel does become available, it is expected to cost about a third more than the conventional product, according to Stegra, a green steel hopeful.

Automakers Pivot to Scrap-Based Solutions

Confronted with these realities, many steelmakers are pivoting to a more cautious, step-by-step strategy centered on electric arc furnaces (EAFs) that can initially run on scrap.

Automakers are also adjusting their procurement strategies:

"We believe that there will be a demand. (But) we are not commercially offering it yet and we are not yet buying it because it is not yet available." Christian Levin, CEO, Traton's Scania

Industry Reaction: Criticism and Cautious Optimism

VDA (German Auto Lobby):

"This means that our industry is once again dependent on developments over which it has no influence." Hildegard Müller, President, VDA

Hydrogen Europe: The industry association welcomed the regulation, calling it a "positive signal" that creates a clear market for green steel.

"Bringing the target date forward to 2030 would further increase the commercial viability of clean steel." Jorgo Chatzimarkakis, CEO, Hydrogen Europe

VDMA (German Engineering Federation): Hartmut Rauen expressed skepticism, arguing that the "theoretically good" idea is undermined by "very detailed specifications." He warned that the precise caps of 7% for steel and 3% for fuels are fraught with uncertainty.

Public Procurement: A 25% Green Mandate for 2029

Beyond the automotive sector, the Industrial Accelerator Act also mandates that from January 1, 2029, a minimum of 25% of steel procured for public projects must be low-emission. This provision is designed to kick-start demand and create a "lead market" for green steel in Europe, independent of the automotive industry's transition.

In a significant move, the Commission dropped a "made in EU" requirement for steel in public procurement, citing a forthcoming new trade measure to address global overcapacity. However, the voluntary label for low-emission steel has also been omitted from the final proposal.

Expert Insight

"There's confusion amongst a lot of people after the Commission's proposal, trying to understand ... what's realistic, what the market would actually look like." Chris Heron, Secretary General, E-Mobility Europe
"In light of the recently proposed trade measure addressing the negative trade-related effects of global overcapacity on the Union steel market, introducing a European preference for steel is not considered necessary." European Commission, on the dropped 'made in EU' requirement

Frequently Asked Questions

Automakers must reduce tailpipe CO₂ emissions by 90% compared to 2025 levels. The remaining 10% can be offset.
Manufacturers can use EU-made CO₂-reduced steel to contribute up to 7% towards their fleet emissions targets. The use of e-fuels can contribute another 3%.
No. Production is nascent and expensive. Green hydrogen is not yet available at scale, and many planned projects have been delayed. It is estimated to cost at least 30% more than conventional steel.
There is currently no agreed-upon definition. The EU had planned to introduce a voluntary label, but it was reportedly scrapped from the final Industrial Accelerator Act due to internal disagreements.
Several are signing long-term contracts with producers. BMW will use Thyssenkrupp's scrap-based steel from 2026, while Porsche has secured a deal with H2 Green Steel for hydrogen-based steel starting the same year.
A legislative package aimed at increasing the manufacturing sector's share of EU GDP to 20% by 2035. It includes measures for green steel, public procurement mandates, and foreign investment rules.
