The Task Force for Corporate Action Transparency’s (TCAT) is committed to developing guidance that works in the real world. Our guidance documents are developed with input and oversight from a wide range of stakeholders.
In Autumn 2025, we held an initial corporate pilot for our first two guidance documents—the Mitigation Action Accounting and Reporting Guidance (MAARG) and the Target Accounting and Reporting Guidance (TARG). A second pilot is running through mid-2026. The companies in these pilots are playing a critical role in validating the usability, clarity, and effectiveness of the guidance.
Additionally, TCAT is conducting a public consultation in early 2026. The second version of the guidance documents will be finalized and published within a year of the end of the consultation, and will reflect inputs from both the pilots and consultation. Reach out if you’d like us to contact you when more details about upcoming consultation opportunities become available.
Pilots
A group of leading companies is piloting TCAT’s draft guidance documents, the MAARG and the TARG.
Through these pilots, participating companies are testing and applying the draft guidance across a range of sectors and use cases. Their feedback will help ensure that the MAARG and the TARG are complete, grounded in real world applicability, and support high-integrity corporate climate action.
Participation in the pilots does not imply endorsement of or a commitment to follow the guidance in its current form or any future guidance. Rather, it reflects a shared ambition to support the development of transparent climate accounting and reporting guidance.
Pilot 1 was held in late 2025. An overview of results from Pilot 1 can be found here.
Pilot 2 is currently underway. Additional details on Pilot 2 can be found here.
More than 20 organizations have taken part in our pilots, including:
