About us

The Carbon Trust Scheme Owner (CTSO) is the legal entity responsible for the governance and oversight of the Carbon Trust Footprint Label. This entity operates separately to the Carbon Trust to ensure impartiality and avoid conflicts of interest. We set the scheme’s technical requirements, approve and oversee assurance partners, and maintain the processes that safeguard the label's independence and integrity.

The Carbon Trust Footprint Label is designed to ensure carbon claims are credible, transparent, and independently verified. Through rigorous technical requirements, independent governance and a network of approved assurance partners, we help organisations to communicate with confidence. Our label also supports compliance with evolving regulatory requirements, including the EU Empowering Consumers for the Green Transition (EmpCo/ECGT) Directive.

The Carbon Trust Footprint Label has been designed to reflect key expectations for environmental labels, such as independent verification, transparent governance, public accessibility of information, and effective complaints and appeals processes. Together, these safeguards protect the Scheme’s integrity and help maintain trust in every label we issue.
