In spring 2026, the European Commission formally approved €5 billion in state aid for Germany's industrial decarbonization program, Klimaschutzverträge (Climate Protection Contracts). The program targets three sectors bearing the heaviest carbon costs in Europe: steel, chemicals, and cement. At its core is a straightforward idea: the government contractually absorbs the primary barrier preventing companies from committing to decarbonization investment — the uncertainty of future carbon prices.
The implications extend well beyond Germany. If CBAM is the regulatory stick imposing carbon costs on imports, Klimaschutzverträge is the subsidy carrot driving the shift to low-carbon production. With Europe now running both wheels in earnest, the carbon intensity of production is becoming a structural business issue for supply chains that supply materials and intermediate goods to the European market.
The Carbon Contract for Difference — Government Absorbs Carbon Price Risk
A Carbon Contract for Difference (CCfD) applies the logic of financial derivatives to decarbonization investment. Before committing capital to low-carbon processes — hydrogen-based steelmaking, electric arc furnace conversion, CCS installation — companies face a fundamental price risk: what will carbon prices actually be? If market carbon prices fall below the level needed to recover the investment, the project runs at a loss. This is where the CCfD intervenes.
The mechanism begins with a government and company agreeing on a reference carbon price — the "strike price." When the actual EU ETS price falls below the strike price, the government covers the difference. When the market price exceeds it, the company repays the difference. The contract guarantees a floor for investment recovery and allows companies to share long-term capital investment price risk with the government.
Two-Way Obligation
The government pays when prices fall, but companies repay when prices rise. This is not a subsidy but a mutual sharing of price risk — a design that limits fiscal exposure.
Long-Term Contracts up to 20 Years
Contracts can match the useful life of the equipment. This duration is designed to unlock large capital investments — electric arc furnaces, hydrogen reduction plants — that short-term subsidies cannot move.
Allocation by Competitive Tender
Companies bid on the subsidy amount they require, and the most efficient proposals are selected first. The mechanism optimizes public spending through market competition.
What distinguishes this from a conventional subsidy is the company's obligation to pay the government when prices exceed expectations. The bidirectional sharing of risk and gain makes fiscal costs more predictable and prevents companies from capturing windfall profits.
Steel, Chemicals, Cement — Why Markets Cannot Deliver This Alone
Klimaschutzverträge prioritizes these three sectors for both technical and economic reasons. They are classified as hard-to-abate industries: they generate substantial process emissions inherent to the manufacturing process itself — emissions that cannot be eliminated simply by switching to renewable energy — and alternative technologies remain costly.
In steel, the conventional blast furnace–basic oxygen furnace (BF-BOF) process uses coke to reduce iron ore, making CO₂ emissions unavoidable. Combining direct reduced iron–electric arc furnace (DRI-EAF) with hydrogen reduction enables significant cuts, but capital expenditure and production cost remain barriers.
This chart is more than a technical comparison. The CO₂ gap between BF-BOF and hydrogen reduction reaches approximately 2 tCO₂/t crude steel. At a hypothetical EU ETS carbon price of €70/tCO₂, that translates to a carbon cost differential of up to €140 per tonne of steel — a competitive factor that is difficult to ignore in a globally price-competitive market.
Cement faces a similar constraint: CO₂ is released during the calcination of limestone, so fuel switching alone has limited impact. In chemicals, ammonia synthesis and basic chemical production processes are structurally heavy consumers of hydrogen and carbon. In each case, transforming the manufacturing process itself requires capital investment on a decade-long timeline and earnings assurance throughout. The CCfD provides that institutional foundation — a reason to invest.
As CBAM Raises the Carbon Cost of Imports
The Klimaschutzverträge approval coincides with CBAM's full enforcement phase. From January 2026, importers of steel, cement, aluminum, fertilizers, electricity, and hydrogen from outside the EU are required to acquire and surrender CBAM certificates in proportion to embedded emissions. Exemptions apply in some sectors for imports below 50 tonnes per year, but this threshold carries no practical significance for major suppliers. Worth noting for cash flow planning: while import transactions in 2026 generate the obligation, certificate acquisition begins no earlier than February 2027, with the first declaration and surrender deadline on 30 September 2027.
As EU-based companies use CCfDs to shift to low-carbon production, CBAM imposes carbon costs on competing imports from outside the EU. The structural implication is that low-carbon production advantage becomes increasingly reflected in price in the European market. Suppliers that have historically maintained price competitiveness by externalizing carbon costs appear to be on a trajectory of gradually losing that advantage.
Concurrently in Japan, the GX-ETS (Green Transformation Emissions Trading Scheme) began applying to carbon-intensive industries in fiscal year 2026. The gap in carbon price levels and regulatory maturity between Japan and Europe remains significant, but the picture of multiple carbon regulations beginning to move in concert within global supply chains is a factor worth keeping in view.
When the Starting Point for Design and Procurement Shifts
If Klimaschutzverträge allows European primary materials producers — steel, chemicals, cement — to accelerate investment decisions toward low-carbon processes, the impact propagates upstream across the entire supply chain. BCG research indicates that companies' Scope 3 emissions (indirect supply chain emissions) average 26 times their direct operational emissions (Scope 1 and 2). A change in the carbon intensity of primary materials cascades through the emissions profiles of manufacturers that procure from them.
The Carbon Intensity of Procured Materials Changes
If European steel and chemical producers use CCfDs to accelerate low-carbon transition, the emission intensity of procured materials falls. This is a change that may function as an upstream measure for Scope 3 reduction.
The Carbon Cost of Exports to Europe Is Scrutinized
CBAM certificate acquisition and surrender obligations are fully in effect from 2026. Materials and component manufacturers with export lines to Europe face mounting pressure to refine their manufacturing process emissions data.
Competitors' Production Cost Structures Change
European manufacturers installing low-carbon equipment with state support will see their manufacturing cost structures shift over the medium to long term. A development worth tracking in investment decisions and competitive analysis.
The European Commission is also advancing technical work on expanding CBAM's scope beyond the current six sectors to downstream products such as automotive steel and packaging materials. The data on how Klimaschutzverträge reshapes European manufacturing costs and carbon intensity serves as the common starting point — for assessing the gap against in-EU competitors and for estimating the cost of exporting to the European market.
