Carbon & ESG reporting for Steel — EAF (electric arc)

Electric-arc steelmaking melts scrap with electricity: direct (Scope 1) emissions drop to ≈0.4 t/t — graphite electrodes, natural-gas burners, lime calcination — and the bigger lever moves to Scope 2: the carbon intensity of the grid that powers the furnace. For the reporting desk that means: which frameworks bite, which KPI to disclose, and which completed measure to show. Here is the steel profile.

Frameworks in scope

FrameworkApplies to steel?
EU ETS (if EU site)Yes — full free-allocation phase-out applies
CBAM (if exporting to EU)Yes
SECR (if large UK company)Yes — energy, Scope 1+2, intensity ratio, efficiency actions
ESOS (if large UK undertaking)Yes — audit by 5 Dec 2027 (Phase 4) + public action plan
CSRD / ESRS E1 (if large EU company)Yes — actions (E1-3), targets (E1-4), energy (E1-5), Scope 1-3 (E1-6)
Customer SBTi / CDP requestsSector-independent — arrives with the RFQ

The KPI to report

The intensity ratio your sector benchmarks against: ≈0.4 t CO2/t steel direct (scrap route; worldsteel). SECR requires an intensity metric of your choice; ESRS E1-5 wants energy per net revenue; CBAM (where in scope) uses exactly t CO2 per tonne of product. Reporting the same physical KPI everywhere keeps the numbers reconcilable — and auditors happy.

The efficiency line — computed for this sector

~60% of steel CO2 is fuel-side — the share efficiency measures can touch. Heat-loss surveys typically recover 2–5% of fuel use, i.e. 1.2–3.0% of this sector's total CO2, at up to-2-year payback. Worked example at a 500,000 t steel/yr site (≈200,000 t CO2/yr at the benchmark intensity): an insulation programme is worth 2,400–6,000 t CO2e/yr — a complete, verifiable entry for SECR disclosure 4, an ESOS progress update, ESRS E1-3 and the tender CRP, plus €185,760+ off the carbon bill where ETS/CBAM applies.

Paste-ready disclosure line: "Heat-loss elimination via removable modular insulation across the steam/condensate system (ASTM C680 survey): estimated 2,400–6,000 t CO2e/yr Scope-1 reduction at benchmark production, payback up to 2 years, metered verification in progress."

FAQ

Questions on this topic

What carbon reporting applies to steel companies?
Large UK steel companies file SECR disclosures and ESOS audits; large EU ones report under CSRD/ESRS E1. Sites are inside the EU ETS, and exports to the EU are in CBAM scope — embedded emissions per tonne must be declared by the importer. Customer SBTi/CDP questionnaires apply regardless of size.
What intensity KPI does steel report?
The sector benchmark is ≈0.4 t CO2/t steel direct (scrap route; worldsteel). Use the same physical KPI across SECR, ESRS E1-5 and customer questionnaires so the numbers reconcile.
What efficiency saving can a steel site book in its report?
With ~60% of emissions fuel-side, heat-loss elimination typically recovers 1.2–3.0% of total site CO2 (2–5% of fuel) at up to-2-year payback — sized in tonnes it is usually the largest single completed initiative available in year one.
