Carbon Costs Turn Decarbonisation Into a Market Edge

Carbon is turning into a direct cost on corporate balance sheets, and acting on emissions early now delivers a higher return than holding back in several markets, particularly across Europe. That is the finding of McKinsey advisers Martin Bohmert and Tim Vroman, whose opinion piece reports that “the penalty for delay is becoming quantifiable”.

Two European mechanisms sit behind the shift. The EU Emissions Trading System (ETS) is set to phase out free allowances by 2034, with a July 2026 European Commission proposal to push the deadline to 2038. The Carbon Border Adjustment Mechanism (CBAM) applies a carbon price to imports across cement, iron and steel, aluminium, fertilisers, hydrogen, and electricity. At projected carbon prices of €150 per tonne of CO₂, the analysis estimates up to €1 billion in annual value at stake for large cement producers by 2030. Importers that supply verified emissions data can reduce their CBAM liability by up to 60% relative to penalty-level default benchmarks.

Supply scarcity sharpens the signal. Demand for low-carbon steel is projected to outstrip available supply by roughly 35% by 2030, with a gap near 31% for aluminium. Buyers that lock in supply agreements early secure both access and price, ahead of premiums that climb as demand builds. Corporate commitments already track this logic: BASF has set a €1.2 billion green transformation budget for 2026 to 2029, and SSAB is progressing a €4.5 billion electric steel mill in Luleå, Sweden, now classed as an EU strategic net-zero project.

Capturing the value depends on execution. The strongest performers rank decarbonisation initiatives by cost savings, margin protection, and risk reduction, then move fastest on the ones that pay for themselves. Embedding carbon into procurement carries its own return: verified supplier data can cut CBAM exposure by up to 60% against default benchmarks, making supplier engagement one of the highest-return actions available.

The authors frame the change as a reset on the basis of competition. They expect the coming decade’s front-runners to be the companies that pinpoint where sustainability adds value and capture it faster than their competitors do.
