Key Takeaways

• Tata Steel is the only major global steel company with fully integrated steelmaking operations in both India and two EU member states (the UK, which applies an equivalent UK ETS carbon price, and the Netherlands under the EU ETS). This dual-geography presence makes it uniquely positioned to observe — from a single company’s P&L — the direct financial difference between operating inside the EU carbon pricing system and being subject to CBAM from outside it. The comparison is analytically clean because the same company, with the same corporate governance and technology access, operates under both frameworks simultaneously.
• Tata Steel India’s Jamshedpur complex — producing approximately 10 MMT of crude steel annually — operates via the blast furnace BOF route with an embedded GHG intensity of approximately 2.0–2.2 tCO₂/t (Scope 1 plus Scope 2 at India’s WAEF 0.710). Tata Steel’s Kalinganagar greenfield plant in Odisha, commissioned in two phases with a 5 MMT target capacity, has marginally lower intensity due to newer equipment but remains in the BF-BOF range. Indian-origin Tata Steel material exported to the EU — primarily plates, sections, and specialty products — carries a CBAM certificate obligation at the prevailing EU ETS price.
• Tata Steel Netherlands (IJmuiden) operates one of Europe’s largest coastal integrated steelworks at approximately 7 MMT annual crude steel capacity. IJmuiden is covered by the EU ETS and pays the carbon price directly on its Scope 1 emissions. Its embedded emission intensity is approximately 1.8–2.0 tCO₂/t currently — lower than India but not dramatically so — but it benefits from the EU ETS free allocation phase-out schedule that CBAM is designed to mirror. Critically, IJmuiden steel sold within the EU does not face CBAM; it faces the EU ETS obligation directly on production.
• Tata Steel UK (Port Talbot, Wales) announced in September 2023 that it would close its last two blast furnaces — effectively ending primary steelmaking in the UK — and transition to electric arc furnace steelmaking by 2027, with a £1.25 billion investment including £500 million in UK government grant funding. The Port Talbot decarbonisation is the clearest example of how the carbon cost structure of the European market — a combination of EU ETS (UK equivalent) carbon price, CBAM pressure on competitors, and green procurement requirements — creates an investment case for technology transition that is not yet present in India’s market at equivalent scale.
• The capital allocation implication for Tata Steel as a group is significant. The company’s European operations — both IJmuiden and the post-2027 Port Talbot EAF — are decarbonising at pace driven by the EU carbon price signal. The company’s Indian operations face CCTS GEI targets (at modest Phase 1 reduction levels) and CBAM exposure on a portion of exports — but the Indian carbon price signal is currently Rs 1,740/tCO₂e (approximately €18.60) versus EU ETS €84.20, a factor of 4.5 differential. This differential means that the investment case for a major technology transition at Jamshedpur or Kalinganagar — say, a DRI-EAF shaft furnace or a large-scale open access RE procurement — is not yet as strong as the equivalent investment case in the Netherlands or UK, where the carbon price is five times higher.
• However, Tata Steel India exports approximately 1.5 to 2.0 MMT per year to markets where CBAM or equivalent carbon pricing applies — primarily the EU, UK, and Japan. At €84.20/tCO₂e EU ETS and 2.1 tCO₂/t Indian embedded emission, the CBAM cost on 1.5 MMT of EU exports is approximately €116 million per year — approximately Rs 1,035 crore annually. This is the direct cost of the India-Europe carbon price differential on Tata Steel’s existing export volume. As CBAM scales to full implementation in 2034, and as the EU ETS price is projected to rise toward €120–150/tCO₂e, the CBAM annual cost on equivalent volumes would reach approximately €170–220 million per year — a cost that begins to rival the capital cost of a major decarbonisation investment at Indian operations.
