The European Union Emissions Trading System and Its Implications for Nigerian Oil and Gas Exports

This study analytically examines the implications of the European Union Emissions Trading System (EU ETS) and the EU Carbon Border Adjustment Mechanism (CBAM) for Nigerian oil and gas exports to European markets, as the EU accelerates its energy transition and introduces carbon pricing on imported goods. Nigeria's economy remains deeply dependent on hydrocarbon exports, and the EU is a significant market for Nigerian crude oil and liquefied natural gas (LNG). The introduction of CBAM and the progressive tightening of EU ETS sectors, including the planned inclusion of maritime shipping, create material financial and market access implications for Nigerian energy exporters. This analytical study draws on EU ETS regulatory documentation, CBAM impact assessments published by the World Bank and UNCTAD, NNPC and Nigerian Upstream Petroleum Regulatory Commission (NUPRC) export data, and academic literature on African hydrocarbon exporters' exposure to EU climate policy published between 2021 and 2024. The study models the financial exposure of Nigeria's major export commodity streams to CBAM and ETS cost pass-through scenarios, using sectoral trade flow data and carbon intensity benchmarks. Findings fill a gap in empirical literature on the downstream trade policy consequences of EU climate regulation for major African oil and gas exporters. Keywords: EU ETS, CBAM, Nigerian oil exports, carbon pricing, energy transition.
