Sovereign Climate Finance in Africa: Converting National Plans into Investable, Accountable Infrastructure Pipelines

IN BRIEF

• The Green Climate Fund approved the Africa Sovereign Climate Facility on 28 October 2026 for Angola, Benin, Côte d’Ivoire and Nigeria. The GCF project page records USD 274.96 million of GCF finance and USD 399.92 million of co-financing, for a total project value of approximately USD 675 million.
• Africa Finance Corporation's 30 October launch announcement describes total financing of USD 690 million and a parallel AFC commercial facility of up to USD 260 million with a tenor of up to ten years. These public figures should be reconciled in implementation documents before project-level commitments are compared.
• The facility combines grants for technical assistance with sovereign loans channelled through ministries of finance. It targets energy networks and storage, renewable access, food systems, water and sanitation, and climate-resilient infrastructure.
• The central implementation risk is not a shortage of eligible ideas. It is the conversion gap between national priorities and projects that have a defined service, credible climate rationale, complete preparation, affordable fiscal path, capable delivery entity and measurable public outcomes.
• StoneComms proposes a six-gate Climate Project Conversion Test: public mandate; climate materiality; delivery readiness; fiscal durability; accountable procurement; and measurable service. A project should advance only when evidence at each gate is sufficient for the next capital commitment.
• Primary SDG 13 and relevant SDGs 9, 16 and 17 classify the paper's direct focus on climate action, infrastructure, public institutions and financing partnerships. These tags indicate relevance, not measured impact or United Nations endorsement.

THE POLICY SIGNAL

On 28 October 2026, the Green Climate Fund approved FP313, the Africa Sovereign Climate Facility. The first phase covers Angola, Benin, Côte d’Ivoire and Nigeria. GCF describes a public-sector facility in which grant finance supports technical assistance to refine projects, integrate climate into macroeconomic and fiscal planning, and strengthen monitoring. Loans from GCF and Africa Finance Corporation are to be passed through ministries of finance for projects in energy transmission, distribution and storage, renewable-energy access, food systems, water and sanitation, and climate-resilient infrastructure. Source: https://www.greenclimate.fund/portfolio/projects/fp313

The policy signal is significant for two reasons. First, it places ministries of finance at the centre of climate implementation. Climate portfolios have often been led by environmental institutions that hold the policy mandate but do not control public investment planning, debt management or sovereign borrowing. The facility links climate priorities to the institutions that approve capital budgets and carry fiscal risk.

Second, the facility joins project preparation and financing. Many climate plans identify priority sectors and outcomes without resolving land, design, demand, procurement, delivery and operating questions. A facility that funds preparation before committing large loans can reduce the risk of financing an attractive concept that has no credible delivery path.

The GCF project page records total project value of USD 674.88 million when the disclosed financing components are added: USD 274.96 million of GCF finance and USD 399.92 million of co-financing. Its rounded headline is USD 675 million. The Africa Finance Corporation's 30 October launch announcement describes total financing of USD 690 million, including GCF finance stated as USD 280 million, and says AFC will arrange and fully fund a parallel commercial facility of up to USD 260 million with a tenor of up to ten years. Source: https://www.africafc.org/news-and-insights/news/afc-and-green-climate-fund-to-launch-us-690-million-africa-sovereign-climate-facility-to-accelerate-climate-resilient-development

The difference is not necessarily a contradiction. The GCF page may report approved, itemised project financing, while the AFC announcement may include a rounded or additional parallel amount. Public materials available at the time of writing do not provide enough detail to reconcile every component. This paper therefore uses the itemised GCF amount when describing the approved structure and the AFC amount only when describing AFC's launch statement. Project documents should publish a common financing table before country allocations, disbursements or leverage claims are assessed.

THE CONVERSION GAP

National climate plans are not investment portfolios. They contain policy objectives, targets, sector measures and adaptation priorities. An investable public project needs a narrower definition: a responsible entity; a specified service; an engineering or operating solution; demand and affordability evidence; environmental and social safeguards; land and permitting; procurement strategy; capital and operating costs; implementation schedule; financing terms; and a system for measuring results.

The gap between those two forms is the conversion gap. It appears when a national plan says that water systems must become resilient, but no utility has completed network diagnostics or defined a financed maintenance plan. It appears when an energy target is translated into a generation asset without confirming the transmission path, customer demand or settlement arrangements. It appears when an adaptation project counts people within a geographic area as beneficiaries without defining the service improvement they will receive.

The UNFCCC's 2025 NDC synthesis report shows why the gap has become central. Among the new NDCs assessed, 75 per cent included climate-finance information and nearly 63 per cent referenced a climate-financing strategy or investment plan. Parties reporting financial needs identified international and domestic, public and private sources; they also cited sovereign instruments, credit guarantees and green credit lines. The direction is clear: national climate commitments increasingly describe financing needs. The next institutional challenge is to turn those needs into a prioritised, governed capital programme. Source: https://unfccc.int/process-and-meetings/the-paris-agreement/nationally-determined-contributions-ndcs/2025-ndc-synthesis-report

The Africa Sovereign Climate Facility can help close the conversion gap if its grant-funded technical assistance is treated as core investment infrastructure. Preparation is not a preliminary administrative cost to be minimised. It is the process that tests whether public borrowing will create a durable public service.

WHAT THE FACILITY CAN FINANCE — AND WHAT IT CANNOT DECIDE

The facility's sectors are intentionally broad. Energy transmission, distribution and storage can improve reliability and integrate renewable generation. Renewable access can extend modern energy services. Food systems can combine irrigation, storage, logistics and resilience. Water and sanitation projects can reduce losses, protect supply and strengthen treatment. Resilient infrastructure can include drainage, transport, public facilities and urban systems.

Breadth creates opportunity, but it does not provide a selection rule. A country could present many projects that fit a sector description. The harder question is which projects deserve scarce concessional finance and sovereign borrowing.

Three distinctions are essential.

Climate relevance is not climate materiality

An infrastructure project may sit in a climate-relevant sector without delivering a material climate benefit. A conventional road, water network or power asset can be relabelled as climate-aligned through a marginal design feature. Climate materiality requires a counterfactual: what climate risk or emissions pathway changes because of the project, and how large is that change relative to the asset's cost and normal development purpose?

For mitigation, the test should identify the baseline emissions, additional reduction and system conditions required for the reduction to occur. For adaptation, it should identify the hazard, exposure, vulnerability, expected service disruption and the population or economic activity protected. The strongest projects integrate climate value into the core service design rather than adding it after the project is selected.

Sovereign eligibility is not fiscal affordability

A project can qualify under facility criteria and still create an unaffordable obligation. Ministries of finance must assess principal and interest, currency exposure, contingent liabilities, operating subsidies, maintenance needs and the risk that project revenues are overstated. Concessional terms reduce financing cost; they do not remove the need for a credible repayment and operating plan.

The parallel commercial facility makes this distinction especially important. Commercial capital may expand the financing envelope and demonstrate market participation. Its shorter or more expensive terms can also increase annual debt service. Each project should show why its financing blend matches the asset's life, revenue profile and public-service purpose.

Asset completion is not service delivery

A completed transmission line, treatment plant or irrigation system is an output. The development result is reliable electricity delivered, safe water supplied, flood losses reduced, food preserved or productive capacity protected. Procurement and results frameworks should define both. Otherwise, projects can be reported as complete while the service remains constrained by staffing, maintenance, tariffs, connecting networks or operating budgets.

FOUR COUNTRIES, FOUR DIFFERENT STARTING POINTS

The facility has a common structure, but the four participating countries do not have interchangeable climate risks, fiscal systems or investment pipelines. Country ownership should mean more than receiving a national allocation. It should shape the project-selection problem.

Angola: climate resilience as economic diversification

The World Bank's Angola Country Climate and Development Report argues that climate resilience and economic diversification are inseparable. Without adaptation, climate impacts could reduce GDP by up to 6 per cent by 2050; direct agricultural losses from drought could rise from as much as USD 100 million per year to more than USD 700 million per year by 2100. Its priority pathways include water management, resilient power, climate-smart agriculture, green cities and human capital. Source: https://www.worldbank.org/en/news/press-release/2022/12/07/angola-s-economic-diversification-and-development-potential-are-inextricably-linked-to-climate-resilience

For Angola, the facility should avoid treating climate infrastructure as a separate portfolio alongside diversification. The strongest projects will protect or enable non-oil productivity. A water investment should show the farms, cities, industries or power systems it stabilises. A renewable-energy project should show how it diversifies supply and supports productive demand. Fiscal appraisal should include oil-price sensitivity and the operating costs that remain after construction.

Benin: adaptation, networks and blended finance

The World Bank's Benin CCDR reports that the country contributes about 0.05 per cent of global greenhouse-gas emissions yet is highly vulnerable. Under a 2.7°C warming scenario, 98 per cent of its territory could be exposed to extreme temperatures by 2070. It identifies agriculture and land use, urban and network infrastructure, and human development as priority resilience areas; it also calls for more private investment, concessional resources and blended finance. Source: https://www.worldbank.org/en/country/benin/publication/benin-country-climate-and-development-report

Benin's first African sovereign SDG bond provides experience in presenting an investment framework to capital markets. That experience should inform, but not substitute for, project-level preparation. The facility can add value by connecting thematic allocation criteria to engineering readiness, service affordability and post-completion performance.

Côte d’Ivoire: protecting growth systems

The World Bank's Côte d'Ivoire CCDR warns that climate change could reduce GDP by around 13 per cent by 2050 and push more than 1.6 million people into poverty. Cocoa, energy and coastal systems are exposed. The country's official climate-finance reporting also points to a large conversion challenge: priority projects in the 2025–2027 public investment programme were estimated at approximately USD 3.42 billion, while about USD 547 million had been received, leaving a reported gap of roughly USD 2.87 billion. Sources: https://www.worldbank.org/en/news/press-release/2023/11/22/cote-ivoire-to-benefit-from-climate-finance-as-key-growth-sectors-threatened-by-climate-change-world-bank-report and https://unfccc.int/sites/default/files/resource/FMCP2_Cote%20d%27Ivoire_en.pdf

Those figures describe an aggregate funding gap, not a verified investable pipeline. The facility should help Côte d'Ivoire rank projects by climate materiality, economic-system protection and delivery readiness. Protecting cocoa productivity, power reliability or coastal infrastructure may create large public value, but each project requires its own technical and fiscal case.

Nigeria: scale, coordination and pipeline discipline

Nigeria's 2025 NDC 3.0 identifies the need to update its climate-finance landscape, strengthen coordination, prepare a climate investment plan, obtain direct access to international climate funds, develop projects with financing propositions, increase private-sector engagement and implement a disaster-risk-finance strategy. It also says existing mitigation, support and adaptation monitoring systems are not fully operational and identifies coordination and capacity constraints. Source: https://www.unfccc.int/sites/default/files/2025-09/Nigeria%20NDC%203.0%20-%20Transimission%20Version%202.pdf

The scale of Nigeria's economy and federal system makes a single central pipeline insufficient. The facility should distinguish projects led by the federal government, states, public utilities and private concessionaires. It should require a common evidence standard while allowing different delivery models. Nigeria's sovereign green-bond experience can support allocation and reporting, but programme-level labels should not replace service-level verification.

STONECOMMS ORIGINAL SYNTHESIS: THE CLIMATE PROJECT CONVERSION TEST

StoneComms proposes six gates for converting a national priority into a financed sovereign project. The gates are sequential in evidence, even when preparation work proceeds in parallel. A project should not receive the next large capital commitment because it has a persuasive narrative. It should advance because the evidence required at the next gate is complete enough for the risk being taken.

Gate 1 — Public mandate

The project must solve a defined public problem and sit within an authorised national or sector plan. The responsible ministry, implementing agency and asset owner must be named. The service area and intended users must be identified. The project should explain why public action is required and whether the state is financing a public good, correcting a market failure or supporting an affordable service.

Evidence should include the policy mandate, institutional responsibility, demand or vulnerability analysis, stakeholder record and a preliminary distributional assessment. A list of NDC measures is not sufficient.

Gate 2 — Climate materiality

The project must define its climate counterfactual. Mitigation projects should quantify the emissions pathway with and without the project, including network, demand and operating assumptions. Adaptation projects should define the hazard, exposure, vulnerability and expected service impact. Cross-cutting projects should show both without double counting.

Evidence should include the climate rationale, baseline, additionality, uncertainty range, scenario tests and the method used to estimate beneficiaries or emissions. The project should disclose which benefits are modelled and which are measured.

Gate 3 — Delivery readiness

The project must have a credible technical, legal and operating path. That includes concept design, options analysis, land and permits, procurement packaging, environmental and social safeguards, implementation schedule, utility connections, workforce and operating arrangements.

Preparation should test alternatives. The selected asset may not be the least-cost or most resilient way to deliver the service. Demand management, maintenance, distributed systems or nature-based measures may outperform a large capital asset in some settings.

Gate 4 — Fiscal durability

The project must be affordable over its full life. Appraisal should show debt service, currency and interest-rate exposure, contingent liabilities, tariff or fee assumptions, public operating support, maintenance and replacement. It should also show the opportunity cost: what other public investment or expenditure is displaced.

The financing blend should match the project. Grants are justified for public goods, preparation, institutional capability and benefits that cannot generate revenue. Concessional loans can support long-lived assets with large public returns and limited commercial finance. Commercial capital should be used where cash flow, risk allocation and tenor support it. A blended structure is not automatically efficient merely because it includes several capital sources.

Gate 5 — Accountable procurement

The procurement model must allocate risk to institutions that can manage it. Bidding documents should specify the service outcome, climate performance, construction standard, operating responsibility and disclosure requirements. Beneficial ownership, contract awards, material amendments and contingent liabilities should be publicly accessible within legal limits.

An engineering, procurement and construction contract may deliver an asset but leave operations with a weak agency. A public-private partnership may mobilise expertise but create an opaque long-term fiscal obligation. The delivery model should follow the service and risk evidence, not a preference for a financial label.

Gate 6 — Measurable service

The results framework must continue after construction. Metrics should cover asset availability, service reliability, users reached, affordability, maintenance, climate performance and distribution of benefits. Adaptation metrics should measure reduced disruption or loss where feasible, not only people within a project area. Mitigation metrics should use actual operating data and updated grid or fuel factors where relevant.

Independent verification, public reporting and a correction mechanism should be designed before first disbursement. If results fall short, the project should have an operating response rather than only a revised narrative.

TECHNICAL ASSISTANCE IS PART OF THE INFRASTRUCTURE

The GCF structure includes grant-funded technical assistance. That is a strength if the grants build capabilities and evidence that remain useful beyond one transaction.

Preparation support should produce shared public assets: climate-risk methods, project-screening criteria, standard terms of reference, fiscal-risk templates, procurement clauses, safeguards capacity, unit-cost benchmarks, operating data and results protocols. These reduce the cost of preparing subsequent projects and improve comparability across sectors.

Technical assistance can fail when consultants deliver reports that are not embedded in government systems. To avoid this, each assignment should name the public process it changes, the staff who will use the output, the data owner and the budget or procurement decision it informs. Training should be attached to a live task, not treated as a stand-alone activity.

Country project-preparation units also need a decision authority. Their role is not simply to accelerate every proposed project. It is to stop weak projects early, redirect designs and concentrate limited preparation resources on the strongest candidates. A credible pipeline contains projects that have been rejected or deferred as well as projects that advance.

FISCAL DISCIPLINE AND THE FINANCING BLEND

Sovereign climate finance sits inside the public balance sheet. Its terms may be favourable, but repayment capacity, foreign-exchange exposure and recurrent costs remain real. The facility should therefore integrate climate appraisal with debt management and public investment management rather than create a parallel approval channel.

Each country programme should publish a fiscal fact sheet for every project. At minimum it should include total capital cost; GCF, AFC and other sources; currency; tenor; grace period; interest basis; government contribution; guarantees; expected project revenue; operating subsidy; maintenance requirement; and material contingent liabilities. It should also disclose whether a state-owned enterprise or subnational government ultimately carries the obligation.

The financing structure should be assessed under downside scenarios. Exchange-rate depreciation can raise the domestic cost of foreign-currency debt. Construction delays can increase interest during construction. Tariff collection can fall below forecast. Climate hazards can damage the asset being financed. The public case should remain acceptable under plausible stress, or the project should be redesigned.

Concessional finance should create additionality. It can extend tenor, reduce the cost of public service, fund preparation, cover climate-specific incremental costs or absorb risks that private capital cannot price efficiently. It should not be used to preserve an unviable tariff, protect an avoidable procurement weakness or crowd out finance already available on reasonable terms.

GOVERNANCE: ONE PIPELINE, VISIBLE DECISIONS

The facility needs a governance architecture that connects climate policy, public investment, debt management, sector institutions and delivery agencies. A practical structure has four levels.

1. National steering: ministries of finance and climate authorities agree the selection framework, portfolio limits and reporting standard.
2. Independent technical challenge: multidisciplinary reviewers test climate rationale, engineering, fiscal risk, safeguards and results before major approvals.
3. Sector delivery: utilities, ministries, municipalities or agencies own implementation and operations, with named accountable officers.
4. Public portfolio reporting: a single register shows project stage, financing, procurement, disbursement, construction, service and climate results.

The public register should record projects from concept through operation. It should show why a project advanced, paused or stopped. It should also separate committed finance, contracted value, disbursement and verified expenditure. Those numbers answer different questions and should not be collapsed into one mobilisation figure.

Portfolio governance should guard against three distortions. Political urgency can push visible assets ahead of less visible network or maintenance investments. Sector agencies can overstate demand to secure a larger allocation. Financiers can favour projects that disburse quickly even when institutional readiness is weak. A common gate process makes those trade-offs explicit.

MEASURING RESILIENCE WITHOUT OVERCLAIMING

The facility is expected to reach 4.5 million people with increased resilience and avoid or reduce 3.4 million tonnes of carbon-dioxide equivalent over its life, according to the GCF project page and the corrected figures in AFC's launch material. These are ex-ante estimates. They provide a planning target, not evidence of impact.

Resilience measurement is particularly vulnerable to overclaiming. A beneficiary count can include every person living near an asset, even if the service improvement is uncertain. Stronger metrics begin with a service pathway. A water project may reduce days of interruption during drought. A drainage project may reduce the depth or duration of flooding for a defined area. A food-system project may reduce post-harvest loss during heat or transport disruption. A grid project may reduce outage exposure for critical services.

StoneComms recommends reporting four layers:

• Inputs: finance committed, preparation completed and capability built.
• Outputs: assets commissioned, systems installed and staff trained.
• Services: reliable electricity, water, transport, food-system or protective service delivered.
• Outcomes: avoided losses, increased resilience, reduced emissions and distribution of benefits.

Each layer should retain uncertainty. A project can verify outputs soon after construction. Climate outcomes may require several years, comparison data or a hazard event. Reports should distinguish observed performance from modelled results and update baselines when material assumptions change.

A PRACTICAL IMPLEMENTATION SEQUENCE

The facility's first four years should be treated as a portfolio-building period rather than a race to announce country allocations.

First 180 days: establish the evidence standard

The partners should publish a common financing table, country-governance arrangements, eligibility and exclusion criteria, the six-gate evidence requirements, disclosure policy and portfolio result definitions. Each country should map existing public-investment and NDC pipelines without assuming that listed projects will be financed.

Months 6–18: prepare and challenge

Technical assistance should fund options analysis, climate appraisal, feasibility, safeguards, fiscal modelling and procurement design for a limited group of candidates. Independent challenge panels should stop or redesign projects where evidence is weak. A first public pipeline should distinguish concept, preparation, approval and procurement stages.

Months 18–36: contract with service conditions

Projects that pass the gates can move to financing and procurement. Contracts should include service and climate-performance requirements, data access, maintenance responsibilities and material-change disclosure. Disbursement milestones should match verified readiness and delivery, not only elapsed time.

Years 3–4: operate, learn and replicate

The first operating projects should produce comparable service data. Governments and financiers should publish what changed between appraisal and delivery, which risks materialised and which preparation investments reduced delay or cost. Replication should follow evidence from operating systems, not simply repeat a financing structure.

RISKS AND COUNTERARGUMENTS

Preparation can become another source of delay

Long appraisal processes can postpone urgent resilience investment. The response is proportionate preparation, not weaker evidence. Smaller, modular and proven interventions can use simplified gates. Large sovereign assets with complex fiscal and social effects require deeper work. Preparation schedules should be published and decision deadlines enforced.

Strict climate tests may exclude development priorities

Countries need infrastructure for development regardless of its climate label. A strong climate-materiality test makes this distinction visible. Projects with high development value but limited climate additionality may deserve other financing. Climate funds should concentrate on projects where the climate case materially changes design, timing, cost or risk.

Public disclosure can conflict with commercial sensitivity

Some financing and procurement information is legitimately confidential during competition. That does not justify permanent opacity. Governments can publish standard fiscal terms, selection decisions, contract awards, beneficial ownership, contingent liabilities and performance data while protecting time-limited bid information.

Sovereign facilities may crowd out local capital

External concessional finance can bypass domestic banks and institutional investors. The facility should assess whether local-currency tranches, co-investment or refinancing can reduce currency risk and deepen local markets. Domestic participation should be driven by appropriate risk and tenor, not by a quota that increases cost or weakens competition.

Results frameworks may reward what is easiest to count

Asset counts and headline beneficiary totals are easier than measuring service and resilience. The remedy is to contract for operational data and define the service pathway at appraisal. Where outcomes cannot yet be observed, reporting should say so.

IMPLICATIONS FOR DECISION-MAKERS

For ministries of finance, the facility is an opportunity to make climate investment part of normal capital budgeting, debt management and fiscal-risk control. A separate climate pipeline should converge with the national public-investment system before approval.

For climate ministries and national designated authorities, the priority is to defend climate materiality and country commitments while helping sector agencies express them as practical project criteria. Their role should continue through monitoring, not end at eligibility confirmation.

For implementing agencies and utilities, the central task is to define the service, operating model and data before procurement. A technically sound asset without an operating institution is not ready for sovereign finance.

For AFC, GCF and co-financiers, the test of blended finance is whether the structure improves project quality, affordability and accountability. The number of capital sources and the headline mobilisation ratio are secondary.

For investors and contractors, transparent gate criteria can reduce late project failure. Clear land, demand, fiscal and procurement evidence improves the quality of competition and makes risks more priceable.

For civil society, legislatures and communities, the public pipeline creates a basis for scrutiny before debt is incurred and after assets begin operating. Participation should address who receives the service, who pays, who bears environmental or social costs and how grievances will be resolved.

COMMISSIONABLE RESEARCH AGENDA

Institutional clients can extend this paper through six focused assignments:

1. Country pipeline diagnostic: map existing NDC and public-investment projects against the six conversion gates, identifying evidence gaps and preparation priorities.
2. Fiscal and currency-risk assessment: model debt service, operating cost, contingent liabilities and downside scenarios for proposed country allocations.
3. Climate-materiality review: test mitigation and adaptation baselines, additionality, beneficiary definitions and measurement methods.
4. Project-preparation operating model: design the mandate, staffing, challenge function, data architecture and decision rights of a national preparation unit.
5. Procurement and disclosure framework: develop standard clauses for climate performance, service data, beneficial ownership, contract variation and public reporting.
6. Portfolio learning system: define comparable service and outcome indicators across energy, water, food systems and resilient infrastructure, with independent verification.

COMMUNITIES AND THE UN SDGS

SDG 13 is primary because the paper directly examines the implementation and financing of national climate priorities. SDG 9 is relevant because infrastructure preparation and reliable service are the main delivery problem. SDG 16 is relevant because public investment, fiscal transparency, procurement and accountability determine whether sovereign finance creates durable value. SDG 17 is relevant because the facility combines national institutions, a multilateral climate fund, a regional infrastructure financier and co-financing partners.

The remaining goals may be served through individual projects, but they are not all direct classifications for this paper. Their relevance depends on the final country portfolios and the services delivered.

This classification indicates relevance, not measured SDG impact. It does not imply United Nations affiliation or endorsement.

CONCLUSION

The Africa Sovereign Climate Facility arrives at an important point in the climate-finance debate. National plans increasingly contain costed needs and investment priorities. Capital remains constrained, but the shortage is not capital alone. It is also the shortage of projects that can connect a climate rationale to a prepared asset, a durable fiscal path, a capable operating institution and a measurable public service.

The facility's design recognises that problem by combining technical assistance, sovereign lending and co-financing. Its success will depend on how firmly it protects the preparation function. Faster disbursement is useful only when it follows stronger evidence. Larger mobilisation is useful only when the financing blend suits the asset and public balance sheet. Higher beneficiary totals are useful only when they refer to an observable service improvement.

Angola, Benin, Côte d'Ivoire and Nigeria will begin from different economic, institutional and climate conditions. A common evidence standard can still create value. The six-gate Climate Project Conversion Test provides one such standard: public mandate, climate materiality, delivery readiness, fiscal durability, accountable procurement and measurable service.

Applied consistently, those gates can help the facility do more than finance a first set of projects. They can strengthen the sovereign investment systems through which climate priorities become infrastructure. That institutional conversion is the facility's most important potential legacy.
