A key United Nations body overseeing the Paris Agreement carbon crediting system has sounded the alarm over funding shortfalls and uneven progress, even as it rolls out the first generation of rules meant to ensure high-integrity carbon markets.
In its fourth annual report, the Supervisory Body for the mechanism under Article 6.4 of the Paris Agreement said it had “established a robust framework for high-integrity carbon credits,” but warned that its operations remain “not yet self-financing.” The group reported a funding gap of roughly $13 million this year and urged governments to step in, calling the shortfall a “critical constraint” to scaling the global carbon market mechanism.
The body adopted new standards on baselines, additionality, leakage, and non-permanence — technical criteria that determine whether projects genuinely cut emissions rather than simply shifting them elsewhere. It also approved the first full methodology for capturing and using landfill gas and accredited 10 verification entities to validate projects.
Despite these advances, officials noted that demand for Article 6.4 credits remains uncertain, hinging on whether governments will use them toward their national climate goals. The report also highlighted the transition of 14 projects from the older Clean Development Mechanism, mostly in least-developed countries, but cautioned that broader participation will depend on “targeted capacity-building” for developing nations.
The Article 6.4 mechanism, sometimes called the Paris Agreement’s carbon market engine, aims to replace the Kyoto-era offset system with a more transparent, globally recognized structure. Its progress comes as voluntary carbon markets face credibility crises and as countries eye cross-border crediting to meet tighter 2030 climate goals.
