Montreal Protocol parties agree $695 million for next three-year ozone fund

A fund built around treaty obligations

The Multilateral Fund helps developing countries meet Montreal Protocol obligations through projects, technical guidance and capacity building. For the next triennium, its role includes financing eligible incremental costs as countries complete the phase-out of hydrochlorofluorocarbons (HCFCs) and continue phasing down hydrofluorocarbons (HFCs). The two chemicals have different environmental profiles: HCFCs deplete ozone, while HFCs are potent greenhouse gases used largely as refrigerants. The fund sits alongside the treaty’s controls; it does not replace them. ^{[3] [2]}

A three-year replenishment is a financing decision, not a single grant. The parties agree the broad resource level; the Fund’s governing bodies then consider work plans and individual proposals. The Executive Committee considers project proposals, and the Fund publishes its decisions. A project count or approval total therefore cannot, by itself, show whether countries received equipment, training or other support in time to meet their obligations. Looking at approvals, disbursements and implementation together gives a more useful picture of delivery. ^[4]

Why the technical estimate is not a simple comparison

Before the meeting, the Technology and Economic Assessment Panel estimated a 2027–2029 funding requirement ranging from US$1.282 billion to US$1.755 billion across its scenarios. The estimate grouped needs for HCFC phase-out, HFC phase-down, institutional strengthening and standard activities. It was a technical assessment prepared before negotiations, not the final budget or a forecast of what would be spent. ^[2]

It would be tempting to subtract the agreed US$695 million package from that range and label the result a shortfall. That would overstate what the two numbers alone establish. The estimate uses scenarios and resource-allocation assumptions; the agreed package explicitly includes carry-over, while the assessment explains that carry-over and interest from the prior period feed into the total fund budget. Comparing adequacy requires matching definitions, accounting for the resources actually available, and seeing how the parties translate the agreement into approved allocations. The difference is a prompt for scrutiny, not a standalone verdict. ^{[1] [2]}

The previous 2024–2026 replenishment was US$965 million, including a substantial carry-over component. That history is another reason to track the ingredients of each cycle rather than treating the headline as a like-for-like measure of new government payments. The official Fund describes replenishment as a decision taken every three years based on a TEAP assessment of developing-country needs. ^{[3] [2]}

Follow the route from agreement to outcomes

For an outside reader, three checkpoints make this decision easier to follow. First, look for the adopted replenishment decision and its contribution scale: these clarify the formal basis of the package. Second, follow the Fund’s approved work programme and country project decisions. Those records show which activities are eligible and how funding is allocated, rather than implying that all resources move at once. The Multilateral Fund maintains a public decisions repository for this purpose. ^{[1] [3]}

Third, compare approvals with implementation reporting over the 2027–2029 period. Training technicians, changing manufacturing processes and improving refrigerant management take time; a signed package is an enabling input, not evidence that a phase-out or phase-down has already happened. The TEAP assessment spans a wide range of work, from transition costs to institutional support and monitoring, so a balanced progress check should examine both environmental compliance and whether support reached the countries and sectors facing the work. ^[2]

The Kigali outcome is therefore best read as a negotiated resource envelope with a clear accounting split and a longer implementation trail ahead. Its environmental significance will become measurable through the decisions and results that follow: funds committed, projects delivered, and treaty targets met. The figures are an important starting point, but they are not a substitute for that record.
