✅ Reported Environmental Achievements
- Reduced GHG emissions intensity (scopes 1 and 2) to 0.91 tCO2e/t of steel (still less than half the global sector average)
- 93% reuse of co-products
- 98% of water used in production reused
- 66% of electricity from renewable and low CO2 emission sources
- 70% of steel produced from recycled scrap (11 million tons recycled annually)
- Approximately 16 million tCO2 sequestered in planted forests and 3 million tCO2 in native forests
🎯 Climate & Sustainability Targets
📅 Medium-term
- Reduce scope 1 and 2 GHG emissions to 0.82 tCO2e/t of steel by 2031
🔭 Long-term
- Achieve carbon neutrality by 2050
