Corporate climate action is more urgent than ever.

Companies must reduce emissions as quickly as possible. New tools are needed so companies can act with transparency, integrity, and ambition. 

TCAT provides third-party assurable accounting and reporting guidance that is complementary to existing reporting frameworks. It addresses gaps in current corporate accounting guidance and aligns with regulatory disclosure requirements.

The Task Force for Corporate Action Transparency (TCAT) unlocks corporate decarbonization at scale.


The Task Force for Corporate Action Transparency (TCAT) is a new initiative dedicated to strengthening the credibility of corporate climate action through transparent, verified, and third-party assurable accounting and reporting guidance.

TCAT’s mission is to equip companies, investors, and other stakeholders with rigorous, practical tools and frameworks to support high-integrity climate action and disclosure. In an evolving accounting landscape, TCAT will serve as an independent and trusted source of technical guidance that clarifies what constitutes measurable, transparent and verifiable corporate climate impact.

TCAT will develop, publish, and promote technical guidance and methodologies that help companies

  • Report emissions reduction and removal efforts transparently and clearly

  • Address gaps in financial and greenhouse gas accounting, reporting, and assurance by developing and aligning with best-in-class standards and practices

This work may include the creation of reporting templates, updated accounting methodologies, decision frameworks, and assessment tools—especially in areas where existing standards are fragmented, unclear, or rapidly evolving.
