Forty-five countries – roughly one-quarter of Paris Agreement parties – have failed to submit their third-round nationally determined contributions (NDCs) with 2035 emissions targets, eighteen months after the February 2025 deadline, leaving a significant gap in the global mitigation framework ahead of the next UNFCCC stocktake. The Paris Agreement Implementation and Compliance Committee (PAICC) confirmed the shortfall in its July 2026 meeting report, noting that twelve governments have ignored repeated outreach and that the committee itself remains split on whether to name non-compliant parties publicly. With no enforcement mechanism built into the treaty, the credibility of the five-year ambition cycle now rests on peer pressure and domestic politics rather than legal consequence.
The compliance gap behind the 2035 ambition cycle
The Paris Agreement requires each party to submit a progressively more ambitious NDC every five years. The first round came in 2015, the second in 2020-2021 (delayed by COVID-19), and the third – covering targets through 2035 – was due by February 2025. As of the PAICC’s 7-10 July 2026 meeting, 45 nations had not delivered. Oman submitted its plan shortly after the meeting, reducing the count to 44. The missing cohort splits into two distinct groups: medium-sized emitters whose absence materially affects global totals, and smaller developing states where capacity constraints dominate.
Egypt, Vietnam, Argentina and the Philippines each rank among the world’s 40 largest greenhouse gas emitters. Egypt’s most recent NDC (submitted 2022) targets a 33% reduction in electricity-sector emissions by 2030 conditional on finance; Vietnam’s 2022 update pledged net zero by 2050 with a 2030 peak conditional on international support; Argentina’s 2021 plan aimed for a 27.7% cut below business-as-usual by 2030; the Philippines committed to a 75% reduction over 2020-2030, almost entirely conditional. Without updated 2035 targets from these four alone, the UNFCCC’s next global stocktake – scheduled for 2028 – will lack credible pathways for roughly 3.5% of current global emissions (approximate context, not from source). The remaining non-submitters are predominantly least-developed countries and small island states in Africa and the Caribbean, many of which lack the institutional capacity to compile economy-wide emissions inventories, model mitigation scenarios, and conduct the stakeholder consultations the NDC process demands.
Sudan’s case illustrates the fragility: a letter from a Sudanese official to the PAICC, seen by Climate Home News, cites civil war as the reason for suspended NDC preparation. That explanation is likely shared, informally, by several other conflict-affected or administratively collapsed states. The PAICC’s mandate is facilitative, not punitive; the treaty’s architects deliberately omitted enforcement powers because negotiators judged that compliance mechanisms would have deterred participation. The committee can only invite non-compliant parties to its next meeting (1-4 September 2026) to “identify challenges and constraints” – a diplomatic euphemism for diagnosing why the process has stalled.
How missing NDCs distort investment signals and grid planning
That points to a structural mismatch: the Paris Agreement’s ambition cycle assumes functioning state capacity to translate international commitments into domestic policy, yet a quarter of parties cannot meet the procedural baseline. For energy investors and grid planners, the practical consequence is opacity. Project finance for renewables, storage, and grid reinforcement in Egypt, Vietnam, Argentina and the Philippines typically relies on government-published long-term capacity targets and emissions trajectories – data that lives in the NDC or its associated long-term low-emission development strategy (LT-LEDS). When those documents are absent or outdated, developers face higher perceived policy risk, which translates into higher cost of capital. On the order of 50-150 basis points of additional risk premium is typical for projects in jurisdictions with stale or missing climate plans (general industry context, not from source).
Vietnam offers a concrete case: its 2022 NDC and the subsequent Power Development Plan VIII (PDP8) created a pipeline of offshore wind and solar projects predicated on a 2030 emissions peak. Without a 2035 NDC, there is no official signal whether the peak holds, accelerates, or slips – leaving developers uncertain about offtake agreements, grid interconnection queues, and carbon pricing assumptions. Egypt’s renewable auction programme, which has procured over 6 GW of solar and wind since 2014, similarly depends on government commitment to a 42% renewable electricity share by 2030; an updated NDC would confirm or revise that trajectory for the 2030-2035 window. Argentina’s gas-heavy power sector and the Philippines’ coal-dependent grid face analogous planning vacuums.
Cross-cutting trend: the same capacity constraints that delay NDCs also slow the permitting and grid-connection reforms needed to absorb clean energy investment. Southeast Asia’s fragile grids – highlighted in a companion Climate Home News report on 5 August 2026 – exemplify the feedback loop: weak institutions produce delayed climate plans, which undermine investor confidence, which slows the grid upgrades that would make higher renewable shares feasible. The PAICC’s facilitative approach cannot break this cycle; it can only document it.
Who this affects
- Utility planners in Egypt, Vietnam, Argentina and the Philippines cannot finalise integrated resource plans for the 2030-2035 period without official 2035 emissions targets, forcing them to model multiple speculative scenarios instead of a single government-endorsed pathway.
- Renewable energy developers face higher cost of capital and stalled offtake negotiations in non-compliant jurisdictions because lenders and buyers treat missing NDCs as a proxy for policy instability.
- Climate finance institutions (multilateral development banks, climate funds) cannot align new country programmes with updated NDC priorities, delaying deployment of concessional capital for mitigation and adaptation.
- Carbon market participants lack clarity on whether host countries will authorise corresponding adjustments under Article 6 for post-2030 mitigation outcomes, freezing pipeline development in the four major emitters.
What to watch next
- PAICC September 2026 meeting (1-4 September): whether the committee votes to name the twelve non-responsive countries publicly – a precedent-setting move that could shame laggards but risks further disengagement.
- Submission timeline of the four major emitters: any updated NDC from Egypt, Vietnam, Argentina or the Philippines before COP31 (likely late 2026) would signal renewed political commitment and immediately improve investment visibility.
- Capacity-building finance flows: track whether the Green Climate Fund, UNDP, or bilateral donors accelerate NDC-support programmes for the smaller non-submitters; the PAICC report implicitly frames capacity as the binding constraint for most.
- 2028 Global Stocktake inputs: the UNFCCC secretariat’s synthesis report will have to model 2035 trajectories for non-submitters using outdated or proxy data – watch for methodological notes that quantify the resulting uncertainty range.
Bottom line: the Paris Agreement’s five-year ratchet mechanism is functionally broken for a quarter of its parties, not because governments reject the goal but because the procedural burden exceeds the administrative capacity of many states – and the treaty has no tools to close the gap except peer review.
