EU emissions trading reform threatens Saarstahl’s €4.6bn green steel overhaul, CEO warns
EU emissions trading reform could weaken price signals and endanger Saarstahl’s €4.6bn decarbonisation project, CEO Stefan Rauber says, risking competitiveness for low‑carbon steel.
Europe’s planned EU emissions trading reform, unveiled by the European Commission this week, has prompted urgent concern from steelmakers undertaking costly decarbonisation programs. Saarstahl and Dillinger — the two plants owned by Stahl‑Holding‑Saar — are midway through a €4.6 billion transformation to replace blast furnaces with hydrogen‑based reduction and electric melting, and their financing assumptions rely on a steadily rising CO2 price under the EU emissions trading reform framework.
Commission proposes changes that could reduce CO2 prices
The European Commission’s reform proposal aims to adjust supply and demand in the carbon market, but industry leaders warn the measures could lower the overall price of allowances. Saarstahl’s management says a reduction in the CO2 price trajectory would erode the economic case for switching from fossil‑based blast furnaces to hydrogen and electric processes. A softer carbon price would make conventionally produced steel cheaper and undercut the business models built around higher allowance costs.
Saarstahl’s €4.6 billion industrial conversion under way
Saarstahl and its sister plant Dillinger are rebuilding their sites to produce iron sponge with gas and then hydrogen, and to melt steel with electricity rather than coke‑based methods. The group expects per‑tonne emissions to fall from roughly two tonnes of CO2 today to about 350 kilograms after conversion. Construction activity is visible on site, with dozens of cranes erecting foundations and a 6,000‑tonne crane due to be installed as part of preparations for the new facilities.
CEO Stefan Rauber: investments hinge on a rising CO2 price
Stefan Rauber, CEO of Stahl‑Holding‑Saar, told company stakeholders that the investment calculus depended on the assumption of higher carbon prices under the EU emissions trading reform. Public funding of about €2.6 billion has been earmarked by federal and regional authorities, but the remaining share is self‑financed by the company. Rauber warned that if the Commission increases allowance supply or otherwise slows the price rise, the returns that underpin the project’s financing and the behaviour of customers could change fundamentally.
Industry lobbying and questions of compliance
The push for reform has been driven in part by large industrial users seeking relief from carbon costs, including sectors where low‑carbon alternatives are technically limited. Rauber expressed sympathy for industries with genuine technological constraints, such as certain petrochemical processes, while sharply criticising firms that failed to adapt to long‑standing regulation. He argued that many companies have had more than two decades to prepare for a tightening carbon regime and that regulatory backtracking would penalise those who invested in compliance.
Market and customer implications for green steel demand
Beyond direct price impacts, a weaker emissions trading signal would affect demand for low‑carbon products. Corporate buyers who are reducing their own carbon footprints rely on price and regulatory signals to justify premiums for greener inputs. If CO2 prices fall, those incentives can vanish and the market for low‑emission steel may shrink, undermining both manufacturers’ revenue forecasts and wider industrial decarbonisation targets. Rauber noted this secondary effect may be as damaging as any immediate change to certificate costs.
Financing, timing and project risks through 2028
The project timeline remains aggressive: construction has been ongoing for two years and first production with the new processes is scheduled to start in 2028. Banks and other financing partners have signalled support so far, but the company says long‑term policy predictability was a prerequisite for finalising terms. Rauber emphasised that the investment is historic in scale for the group and carries considerable risk, which is amplified if legislative changes alter the market environment the project was designed for.
Europe’s steel decarbonisation drive is at a crossroads as regulatory signals that prompted heavy private and public investment face potential dilution. For Saarstahl and similar projects, predictable and credible carbon pricing is not an abstract policy preference but the financial backbone of a multi‑billion euro shift away from fossil processes. The Commission’s next steps will therefore be watched closely by investors, industrial customers and governments trying to reconcile short‑term competitiveness pressures with long‑term climate commitments.
