The Task Force for Corporate Action Transparency (TCAT) is a group of GHG accounting experts, practitioners, and nonprofit organizations working to build a stronger foundation for high-integrity climate action.

Our goal is simple but critical:

to help companies take meaningful action and create lasting impact by addressing existing gaps in guidance.

The TCAT Senior Advisory Committee

TCAT is overseen by a Senior Advisory Committee that includes senior leaders and experts representing NGOs, climate science, academia, corporate practice, and GHG-accounting standards. Members participate in an independent capacity and provide high-level strategic advice to the Secretariat.

Endorsers of the TCAT Guidance

These NGOs have endorsed TCAT’s two initial guidance documents, the Mitigation Action Accounting and Reporting Guidance (MAARG) and the Target Accounting and Reporting Guidance (TARG). Endorsement signals their support for TCAT’s mission to strengthen the credibility of corporate climate action through transparent, verified, and third-party assurable accounting and reporting guidance.

The TCAT Secretariat

TCAT is run by a Secretariat composed of professionals with deep expertise in corporate climate strategy, GHG emissions accounting, and program and policy design and management. The Secretariat is responsible for developing guidance, coordinating research, managing day-to-day operations, and leading public consultations to ensure broad and diverse stakeholder input.
