CBAM and Brazilian Steel: Why Charcoal-Pig-Iron and Renewable-Heavy Brazilian Grid Make Brazil a Distinctive Case
Brazilian steel CBAM positioning is structurally different from any other major exporter. Two distinctive factors: (1) Brazil's national grid emission factor is approximately 0.10 tCO2/MWh — among the lowest globally, dominated by hydroelectric generation. (2) Brazil has a unique 'charcoal-pig-iron' route used by some smaller integrated producers (mostly in Minas Gerais), where charcoal from sustainably managed eucalyptus plantations replaces coke. This route produces pig iron with significantly lower embedded carbon than coke-based production. Major Brazilian steel exporters are Gerdau, Usiminas, CSN (Companhia Siderúrgica Nacional), and ArcelorMittal Brasil.
The Charcoal-Pig-Iron Distinction
The Brazilian charcoal-pig-iron route — concentrated in Minas Gerais state and used by smaller producers like Vallourec Tubos do Brasil and various smaller mini-mills — replaces coke (made from coking coal) with charcoal made from sustainably managed eucalyptus plantations. The charcoal is biogenic carbon — emissions from its combustion are treated as zero direct emissions for CBAM purposes (subject to verification of sustainable forestry sourcing). For charcoal-pig-iron operations, the upstream pig iron has direct emissions of approximately 0.4–0.7 tCO2/t (vs 1.5–1.9 tCO2/t for coke-based), and the downstream steel actuals are correspondingly lower.
The volume is small (charcoal-pig-iron is a niche route) but the per-tonne CBAM advantage is substantial. For Brazilian producers operating this route, documentation is high-value.
EAF Steel on Brazil's Hydro Grid — The Hidden Advantage
Brazilian EAF steel producers operating on the hydro-dominant national grid (0.10 tCO2/MWh) have a structural advantage that doesn't appear on the surface of CBAM analysis. While steel CBAM scope currently excludes indirect electricity emissions, EU steel customers are increasingly looking at full-scope embedded carbon for their own ESG reporting, BREEAM submissions, and supply-chain decarbonisation targets. Brazilian EAF steel landed in EU markets has a far better full-scope carbon footprint than Chinese or Indian EAF steel — even though current CBAM rules don't fully reflect this. As CBAM scope evolves (potential inclusion of steel indirect electricity in future amendments), Brazilian EAF positioning improves further.
The Major Brazilian Producers
Gerdau is the largest Latin American long-products producer with operations across Brazil and the Americas. Brazilian Gerdau operations are EAF-heavy with renewable-grid electricity — strong CBAM story. Usiminas (BF-BOF integrated, Ipatinga and Cubatão) is Brazil's largest flat-products producer; actuals are close to default. CSN (Volta Redonda integrated complex) is similar. ArcelorMittal Brasil (Tubarão and Monlevade) is also predominantly BF-BOF. The Brazilian CBAM picture is therefore bifurcated: integrated BF-BOF producers face standard exposure, while EAF producers and charcoal-pig-iron operators have distinctive advantages.

Frequently Asked Questions
Why does Brazil's grid emission factor matter for steel?
Currently steel CBAM scope excludes indirect electricity — so the ultra-low Brazilian grid factor (0.10 tCO2/MWh) doesn't directly affect steel CBAM cost today. But EU customers increasingly look at full-scope embedded carbon for their own ESG and supply-chain reporting, where Brazilian EAF steel has a structural advantage versus Asian alternatives.
What is charcoal-pig-iron and why does it matter for CBAM?
A Brazilian-distinctive integrated steelmaking route using charcoal from sustainably managed eucalyptus plantations instead of coke. Charcoal is biogenic carbon — treated as zero direct emissions for CBAM (subject to sustainable forestry verification). Charcoal-pig-iron actuals are approximately 0.4–0.7 tCO2/t versus 1.5–1.9 tCO2/t for coke-based.
Should Gerdau document CBAM actuals?
Yes. Brazilian Gerdau EAF operations on hydro-dominant grid produce steel at very low actuals (0.4–0.8 tCO2/t direct + minimal scrap upstream) versus 2.18 default. Saving of EUR 90–115 per tonne — strong documentation case.
Should Usiminas and CSN document?
Mixed. BF-BOF integrated operations have actuals close to 2.18 default — small documentable savings. The bigger value is the audit trail for ongoing modernisation and the strategic positioning as Brazilian ETS emerges.
Is Brazilian ETS likely to gain CBAM equivalence?
The Brazilian Emissions Trading Scheme (SBCE) is in legislative development. Operational timing is uncertain. Equivalence under CBAM Article 9 would require alignment of allowance prices with EU ETS — currently far apart. Likely 2030+.
