Gold Standard and Verra have collaborated to launch a digital calculation tool that assists with Article 6.2 reporting of corresponding adjustments. The tool is designed to provide host governments with a consolidated dataset of corresponding adjustments along with a calculation tool to simplify their 2026 Biennial Transparency Reports.
To provide some background as to what this tool is designed to achieve, it is helpful to understand two key concepts: Corresponding Adjustments and the Biennial Transparency Report. Under Article 6.2 of the Paris Agreement, countries may authorize the transfer of Internationally Transferred Mitigation Outcomes (ITMOs) for use toward the recipient country’s Nationally Determined Contributions (NDCs) or other eligible international purposes. For authorised mitigation outcomes, participating countries apply a Corresponding Adjustment (CA) to their emissions accounting, reflecting the export or import of mitigation outcomes to avoid double counting.
The CAs are reported within the Biennial Transparency Report (BTR), typically presented in an Excel spreadsheet. The BTR is required by participating parties every other year, and includes national inventories, NDC progress, climate change impacts and adaptation, climate finance, technology transfer, and capacity-building support and needs.
The next BTR submission deadline falls in December 2026, and this new Verra and Gold Standard tool arrives in time to provide host countries with a streamlined approach to CA reporting. The tool provides a comprehensive record of CAs for all authorised credits issued by either of the two registries. After host countries answer five initial questions, the tool generates a Structured Summary that can be incorporated into the BTR reporting process.
Reducing Barriers to Article 6 Participation
Article 6.2 establishes accounting requirements for ITMOs which includes CAs to ensure each emission reduction cannot be counted toward more than one country’s climate target. The accounting mechanism is critical for maintaining confidence in cross-border carbon trading and supporting the credibility of NDCs and international carbon markets.
The importance of this new digital tool was highlighted by the Gold Standard CEO Margaret Kim, who said “Access to carbon markets depends on countries having the tools and infrastructure to participate with confidence. This collaboration removes some of the practical complexity around Article 6.2 reporting, helping host countries access market opportunities while supporting a more efficient, consistent, and credible carbon market overall.”
By simplifying complex processes and providing the tools and infrastructure needed for easier reporting, it reduces administrative burden and addresses a key implementation barrier to participation in Article 6.2 cooperative approaches. Standardized reporting tools can help improve reporting consistency, reduce the risk of reporting errors, and may support broader participation in international carbon markets.
Initiatives such as the Verra and Gold Standard reporting tool demonstrate how digital infrastructure can support Article 6.2 implementation. As countries prepare their 2026 BTRs, tools that improve consistency, transparency, and reporting efficiency may help reduce administrative burdens while supporting environmental integrity in international carbon markets.
