ICVCM seeks to make its Core Carbon Principles the global quality threshold for Article 6

The ICVCM’s new guidebook is intended to help governments use its high-integrity standards when designing national carbon market rules, including the criteria they apply to authorising and trading credits under Article 6.

The CCPs, published in 2023, are ten principles for identifying high-quality carbon credits, grouped into governance, emissions impact and sustainable development. They are applied through an assessment framework that approves crediting programmes and methodologies. By the end of November 2025, the ICVCM had approved seven major crediting programmes and 36 methodologies. It says governments and regulators are increasingly building the CCPs into emissions trading systems, carbon taxes and Article 6 frameworks. CCP-eligible credits can also carry an attribute showing host-country authorisation under Article 6.

The ICVCM describes the CCPs as complementary to Article 6. It notes that Article 6 does not regulate the voluntary market or set credit-quality requirements there, and that the CCPs can help countries use existing voluntary market infrastructure for Article 6 trading. It cites Singapore, where companies may use credits from independent programmes against the carbon tax if they meet extra criteria. A February 2026 study by Perspectives Climate Group, funded by Germany’s economy ministry, assessed how well the CCPs and assessment framework align with Article 6 requirements.

Signals to watch

• A single quality benchmark across markets: If host and buyer governments adopt the CCPs as a minimum standard for authorisation, procurement or compliance use, the gap between voluntary and Article 6 credit quality would narrow. This could reduce due diligence costs for buyers.
• Sovereignty and governance questions: Article 6 is governed by Parties under the UNFCCC, and the PACM Supervisory Body sets its own standards. Some governments may resist making a private standard-setter’s framework the threshold for sovereign decisions. Watch how countries reference the CCPs, as a mandatory requirement or as one acceptable benchmark among others.
• Market differentiation: CCP-labelled credits with an Article 6 authorisation tag could become a premium category for corporate, CORSIA and sovereign buyers. Developers should prioritise CCP-approved methodologies when targeting buyers with strict integrity criteria.
• Interaction with PACM and buyer standards: Germany’s “PACM-aligned” tender, Singapore’s eligibility criteria and the coming EU quality rules for 2036–2040 all create competing reference points. Whether the CCPs become the common denominator or one of several frameworks will shape the market’s structure.
• Implications for host-country frameworks: Countries designing authorisation rules, such as Nigeria, Panama, Ethiopia and Indonesia, could adopt the CCPs to signal integrity to buyers. Doing so may limit eligible project types and methodologies, so governments will need to balance credibility with supply.
