• New protocol enables governments to use private-sector crediting programmes for Paris Agreement compliance, expanding the supply of eligible emission reductions.
• Standardised procedures aim to reduce market risk and improve integrity across Article 6.2 transactions.
• Rollout begins with global pilots in 2025 as countries look for credible pathways to meet NDCs without building national crediting systems from scratch.

Singapore Unveils Framework to Bridge Voluntary and Compliance Carbon Markets

A new protocol published by Singapore’s National Climate Change Secretariat, Gold Standard, and Verra sets out a unified system for countries to use existing independent carbon crediting standards to meet their Paris Agreement targets. The framework arrives as governments seek credible, cost-effective pathways to close widening gaps between current policies and their Nationally Determined Contributions.

The Article 6.2 Crediting Protocol provides governments with a ready-made structure for engaging in cross-border carbon cooperation under the Paris Agreement. Instead of designing national crediting programmes, countries can draw directly on the verification systems used by the voluntary market. For policymakers, it offers speed. For investors and developers, it offers clarity.

A Structure for Governments Turning to Private Standards

Article 6.2 enables countries to trade emission reductions through internationally transferred mitigation outcomes. The complexity of the rules, and the resources required to operationalise them, have slowed progress. By giving governments access to the infrastructure of established standards, the protocol attempts to remove one of the biggest barriers: administrative capacity.

The document clarifies the roles of public agencies, independent standard setters, and project developers. It lays out how authorisation processes, first transfers, retirements, and corresponding adjustments should be handled, and requires a common labelling system within registries. These steps are designed to prevent confusion about whether a carbon credit can be used for NDC compliance or voluntary corporate claims.

Officials involved in the process say the goal is to ensure integrity in a part of the carbon market where inconsistent approaches risk creating mistrust. The protocol’s uniform guidance allows countries to follow a shared blueprint rather than create bespoke systems that vary widely in quality.

Built from COP28 to COP29 and Shaped by Broad Consultation

The idea for a unified protocol was introduced at COP28 in Dubai and refined through 2024. Draft recommendations were released ahead of COP29 in Baku, where governments adopted the Paris Agreement’s Article 6.2 rulebook after several years of negotiation.

Development of the protocol continued through consultations with governments, other independent standards, and market participants. Contributors sought to ensure the document aligned with the new rules while remaining practical to implement, recognising that Article 6.2 cooperation depends on predictable processes and credible reporting mechanisms.

Its structure now reflects consensus on what countries and standards need to do to ensure that mitigation outcomes are traceable, correctly adjusted, and transparently reported to the UN.

Operational Priorities for 2025

Over the next year, Singapore, Gold Standard, and Verra plan to work with governments interested in piloting the protocol. These trials will test registry labels, documentation flows, and the coordination required between national authorities and crediting programmes.

The partners also plan to explore a longer-term governance model, recognising that standardisation must evolve as the Article 6 marketplace grows. Future updates could incorporate dedicated identifiers for internationally transferred mitigation outcomes, guidelines for managing shares of proceeds, and approaches to ensure overall mitigation of global emissions. A data protocol with common reporting fields is also being considered.

Stakeholders expect this next phase to reveal how different countries interpret their obligations under the Article 6.2 rulebook, and how existing voluntary systems can support transparency without adding administrative burdens.

What C-Suite and Investors Should Watch

For corporate buyers and investors, the protocol’s release offers a clearer view of how compliance and voluntary markets may converge. Governments moving toward Article 6 transactions will likely rely on crediting programmes that also serve corporate demand. That creates both opportunities and risks.

Aligned procedures could strengthen confidence in credit quality and reduce regulatory fragmentation. At the same time, tighter government oversight may affect how credits are authorised, labelled, and retired for voluntary claims. Companies with decarbonisation strategies dependent on offsets will need to follow these developments closely to assess how Article 6 adjustments reshape their net-zero plans.

A Step Toward Global Alignment

As countries confront rising climate-finance needs, the protocol provides a credible path to scale up carbon trading while safeguarding integrity. It does not solve the political challenges surrounding Article 6, but it offers governments a functional starting point at a time when many lack the resources to build systems alone.

Its impact will depend on uptake. If widely adopted, the protocol could accelerate the emergence of a more consistent global carbon market—one in which voluntary and compliance systems interact cleanly rather than in parallel. If not, governments may revert to divergent national approaches that limit liquidity and weaken trust.

For now, the publication marks a decisive move by Singapore and two major standard setters to provide structure in a complex, fast-moving arena. Its next test will be whether it can turn shared guidance into operational, large-scale cooperation.
