CBAM Impact on Ghana: Aluminium, Steel, and the Volta River Authority

Ghana and CBAM: The Hydropower Carbon Advantage

Ghana's engagement with CBAM is shaped by one of Africa's most significant carbon advantages: the Akosombo hydroelectric dam. The Volta River Authority (VRA) operates the Akosombo and Kpong dams, which together provide approximately 35% of Ghana's electricity at near-zero carbon intensity.

The VALCO Aluminium Smelter

The Volta Aluminium Company (VALCO) smelter in Tema is Ghana's primary CBAM-exposed asset. VALCO has a production capacity of approximately 200,000 tonnes of primary aluminium per year and draws power directly from the Akosombo dam under a long-term power purchase agreement with the VRA. For CBAM purposes, VALCO's Scope 2 (electricity) emissions are near-zero — a dramatic contrast to the EU default emission factor of 6.745 tCO₂/tonne for aluminium. If VALCO invests in actual emissions measurement and third-party verification, its CBAM cost could be a fraction of the EU default.

Ghana's Steel Sector

Ghana has a growing electric arc furnace (EAF) steel sector, primarily in Tema and Accra. EAF steel production uses electricity rather than coal-fired blast furnaces, and Ghana's partial hydropower grid gives Ghanaian EAF producers a lower carbon intensity than coal-dependent competitors. Key Ghanaian steel producers include Wahome Steel, Ferro Fabrik, and Sentuo Steel — all of which export to EU markets under CN codes 7213–7217 (wire rod, bars) and 7304–7306 (tubes and pipes).

Carbon Pricing: The Missing Piece

Ghana does not have a qualifying carbon pricing mechanism as of 2026. Ghana's NDC commits to carbon pricing in principle, but no ETS or carbon tax has been implemented at a level that would trigger the CBAM Article 9 deduction. This means Ghanaian exporters pay the full gross CBAM cost — but their actual embedded emissions are likely significantly lower than EU defaults.

The Verification Imperative

For Ghana, the single most important CBAM action is actual emissions verification. The gap between EU default emission factors and Ghana's actual embedded emissions (due to hydropower) is likely to be very large — potentially reducing CBAM costs by 60–80% for aluminium. This verification investment pays for itself many times over.

Compliance Pathway for Ghanaian Exporters

1. ▸Calculate actual embedded emissions per tonne using the EU CBAM methodology
2. ▸Engage an accredited third-party verifier (ISO 14065 or EU ETS verification standards)
3. ▸Appoint an Authorised CBAM Declarant registered in the EU CBAM Registry
4. ▸Register at the Digital Product Passport Registry
5. ▸Submit your first CBAM declaration by 31 May 2027
