Decarbonization Costs Reshape Steel Pricing as Green Premiums Emerge

The steel industry's decarbonization push is creating a bifurcated market between conventional blast furnace (BF-BOF) steel and lower-carbon production routes. In Europe, the Carbon Border Adjustment Mechanism (CBAM) is pricing carbon at EUR 80-100 per tonne of steel, adding $80-100/t to imported steel costs and narrowing the price gap with European-produced material.

Green steel premiums of EUR 150-300/t over conventional hot rolled coil are becoming established in Europe as automakers and construction companies seek to reduce their Scope 3 emissions. Several major automotive OEMs have announced targets to source 30-50% of their steel from low-carbon routes by 2030, creating a demand pull for green steel that exceeds current supply.

The transition to EAF-based steelmaking requires significant capital investment. European steelmakers have announced over EUR 20 billion in decarbonization projects, including hydrogen-ready DRI plants and new EAF capacity. However, the availability of sufficient scrap and green hydrogen at competitive prices remains a constraint on how quickly the transition can proceed.

In the US, the EAF production route already accounts for approximately 70% of steel output, giving US producers a carbon advantage versus integrated BF-BOF mills in Asia and Europe. However, the scrap quality required for advanced automotive grades remains a challenge, limiting how far the EAF share can expand in the near term.

The CBAM and similar carbon pricing mechanisms in other markets are expected to widen the cost gap between high-carbon imported steel and domestic production over time. This creates a structural advantage for producers with lower carbon footprints and a cost disadvantage for import-reliant buyers of commodity-grade steel.
