Tata Steel
Field: Emission intensity (Analysis #2)
3.20 tCO2e/tcs reported as India-specific intensity, used in direct comparison with JSW Steel (2.44). Derived '11 Mt' annual reduction figure and '31% gap' claim.
Intensity figure flagged as likely wrong — 66 Mt group emissions (including Netherlands/IJmuiden) divided by India-only production (~20.6 Mt). True India intensity likely in the low 2s. Comparison removed pending sourcing of India-specific intensity. 11 Mt claim and comparison chart removed.
Boundary mismatch: group emissions vs India-only production. The 3.20 figure was identical across both reported years while absolute emissions changed, suggesting a data-entry issue rather than calculated intensity.
Hindalco Industries
Field: Scope 1, Scope 2
S1: 25.30 Mt, S2: 0.44 Mt (FY2024-25, unverified)

Verified from FY2025-26 BRSR. Previous Scope 2 (0.74 Mt) was significantly overstated — actual is 0.25 Mt, dropping to 0.16 Mt.
NALCO
Field: Scope 2
S2: 274,226 tCO2e (FY2024-25)
S2: 90,778 tCO2e (FY2025-26) — 67% drop due to shift to captive power
Added FY2025-26 data showing dramatic Scope 2 reduction.
