The Grand Tortue Ahmeyim LNG project loaded its first cargo off the coast of Senegal and Mauritania in February 2025. The BP- and Kosmos Energy-led floating liquefaction vessel had been under construction for six years, delayed twice by project complexity and a global pandemic. When it finally sailed, it carried with it a question that African energy ministries and development finance institutions have been avoiding in the same breath: what does gas infrastructure that takes a decade to build and runs for 25 years cost a continent that has promised the world a different energy future?

Across the continent, approximately $50 billion in LNG and gas infrastructure is either producing, under final construction, or at final investment decision. ENI’s Coral FLNG off Mozambique has been delivering cargoes since 2022. Nigeria’s NLNG Train 7, a $2.8 billion Shell joint venture, is completing construction and targeting first output in 2025. Tanzania LNG, shelved for years and revived in 2024 by ExxonMobil and Shell with a potential $30 billion price tag, is back in the pre-FID queue. Egypt is expanding Mediterranean gas export infrastructure through Eni and BP concessions. South Africa is evaluating LNG-to-power contracts as a mechanism to replace retiring coal capacity.

The economic case for each of these projects, taken individually, is coherent. Africa has 17 percent of the world’s proven natural gas reserves and consumes a fraction of them domestically. Export revenues fund government budgets that have no alternative near-term source of comparable scale. Gas-to-power, in markets where coal or fuel oil is the counterfactual, reduces emissions in the electricity sector even if it does not eliminate them. And the US Energy Secretary Chris Wright made the argument explicitly at the Powering Africa Summit in March 2026: gas is a transition fuel, LPG for clean cooking saves lives, and American export credit should help pay for it.

What the economic case leaves out is a second balance sheet — the climate finance balance sheet — where the same gas investments carry costs that are only beginning to be quantified.

What the DFI Conditionality Clause Actually Says

At COP29 in Baku in November 2024, the African Development Bank committed to halt financing for unabated fossil fuel projects — aligning with the World Bank’s 2013 restriction on coal finance and the European Investment Bank’s 2021 prohibition on oil and gas financing. The AfDB’s pledge was not legally binding on existing commitments, and its precise definition of “unabated” leaves room for gas projects that can demonstrate a credible carbon capture pathway. But the direction of travel is clear.

For African governments planning LNG infrastructure, the practical consequence is a narrowing pool of concessional co-financing. The EIB will not touch it. The World Bank’s energy financing guidelines effectively exclude unabated gas. The AfDB is now formally moving in the same direction. What remains is commercial debt — at higher rates, on shorter tenors, with fewer risk-sharing instruments — and bilateral export credit from countries that have not made the same commitments. EXIM Bank. Japan Bank for International Cooperation. Korea EXIM. China Development Bank.

“The conditionality is real and it is shifting the cost of capital upward for these projects,” said one senior energy investment officer at a multilateral development bank, speaking on background. “The question is whether African governments are pricing that into their project economics, or whether they are assuming concessional finance will be available on the same terms as ten years ago. It won’t be.”

The IEA’s Africa Energy Outlook 2024 models a scenario in which gas demand in Africa roughly doubles by 2030 under current policy trajectories — but flags that scenario as inconsistent with Paris-aligned financing from multilateral institutions. The financing gap between what African gas projects will cost and what concessional multilateral finance will cover is not a speculative risk. It is a projected certainty.

The NDC Carbon Budget: What Gas Infrastructure Costs the Ledger

African NDCs collectively commit to greenhouse gas reductions that are largely conditional on international climate finance. The African Group of Negotiators has quantified the continent’s financing need at $2.8 trillion through 2030. The practical implication of that conditionality — which is rarely discussed explicitly — is that gas infrastructure that generates emissions creates NDC carbon budget pressure that requires either additional renewable investment to offset, or a revision of NDC targets at Belém.

The math is not simple, because gas-to-power replacing coal-to-power produces genuine emissions reductions. Senegal’s electricity sector emissions trajectory under GTA-supplied gas is lower than under the heavy fuel oil alternative. Nigeria’s unconditional NDC includes gas-to-power as part of its transition architecture. These are real reductions, not accounting fictions.

The complication is at the frontier of what gets measured. LNG export infrastructure — the offshore FLNG vessels, the liquefaction plants, the methane-intensive supply chain — generates significant upstream emissions that are typically reported by the exporting country’s NDC rather than the importing country’s consumption statistics. Mozambique, Tanzania, and Senegal are in the unusual position of building export infrastructure whose carbon footprint sits on their national emissions accounts while the energy value accrues to European buyers. That is not an argument against the economics. It is an argument for pricing it correctly in the NDC.

Carbon Tracker’s analysis of African LNG projects — published in its 2024 unburnable carbon update — estimated that committed LNG export capacity in sub-Saharan Africa would generate cumulative emissions equivalent to 40 to 60 percent of the continent’s aggregate NDC conditional reduction target through 2030. The range is wide because it depends heavily on whether methane leakage from supply chains is measured accurately. African governments have generally not published detailed methane accounting for offshore LNG operations.

The Revenue Africa Is Not Counting: Carbon Credit Opportunity Cost

The least-discussed cost of gas infrastructure is the Article 6 opportunity cost — the carbon credit revenue that countries trading Internationally Transferred Mitigation Outcomes under the Paris Agreement framework cannot earn against emissions reductions that gas projects absorb.

Under Article 6.2 of the Paris Agreement, countries can sell verified emissions reductions to Switzerland, Japan, Singapore, and other buyer nations as ITMOs. The buyer counts the reduction against their own NDC. The seller must subtract it from their own carbon budget. The price currently being paid in bilateral ITMO agreements ranges from $10 to $40 per tonne CO₂ equivalent — substantially above the $3 to $7 that voluntary market credits trade at, and below the $30 to $60 range that high-integrity Article 6 compliance credits may reach as COP30 finalises the rulebook.

Countries that build gas infrastructure and embed those emissions into their NDC carbon budget cannot sell those reductions as ITMOs — the emissions are committed, not additional. The opportunity cost is real: every tonne of NDC carbon budget consumed by gas infrastructure is a tonne that cannot be monetised through Article 6 bilateral sales to Switzerland or Japan.

For a country like Kenya — which has already achieved a 90 percent renewable electricity sector and could generate highly credible ITMOs from continued clean grid expansion — the carbon credit market is a meaningful revenue stream. For Mozambique or Tanzania, where the electricity sector will carry LNG emissions for decades, the Article 6 market will be structurally smaller than it would otherwise be.

The Equation African Finance Ministries Need to Run

The question for African finance ministries and energy planners is not whether gas infrastructure is economically rational in isolation. The question is whether the gas infrastructure decision has been modelled against the full climate finance cost stack: higher-cost commercial debt replacing concessional finance; NDC carbon budget pressure requiring additional renewable investment to meet updated targets; and foregone Article 6 carbon credit revenue over the project’s operational life.

IRENA’s 2024 Africa Renewable Energy Outlook found that the levelised cost of electricity from utility-scale solar across the continent has fallen to $25–40 per megawatt-hour — competitive with new gas-to-power in most markets and below the debt-servicing cost of LNG import infrastructure. For countries that are importing rather than exporting gas — South Africa’s proposed LNG-to-power contracts are the clearest case — the economic case is weakening as renewable costs fall. The climate finance cost is an additional burden on top of an already deteriorating commercial case.

For producing countries — Mozambique, Senegal, Tanzania — the calculus is different. Gas export revenues are real, near-term, and not replaceable with renewable energy revenues in any comparable fiscal timeframe. The argument is not that these countries should forgo gas development. It is that they should model the climate finance cost explicitly and negotiate with DFI lenders and ITMO buyers now — before the infrastructure is built and the budget is committed — rather than arrive at Belém in November with a carbon budget that cannot support the NDC targets they have already signed.

What COP30 Will Demand

COP30 in Belém will be the first full-cycle Paris Agreement review where the emissions trajectory from gas infrastructure decisions made in 2020 to 2026 is visible in the data. African negotiators who arrive with NDC targets that depend on international climate finance, while simultaneously reporting expanding gas sector emissions, will face structural pressure to either revise their targets or demonstrate that the gas and the transition are genuinely complementary — not contradictory.

The countries best positioned at Belém will be those that have run the full equation: gas revenues modelled against DFI conditionality costs; NDC carbon budget modelled against Article 6 opportunity; methane accounting from LNG operations disclosed transparently. That is not the case today for most of the twelve African countries with active gas infrastructure commitments.

The $50 billion is being spent. The question is whether the climate finance cost is being counted.
