Setting the LEAF Marque Standard

Learn more about how we set the LEAF Marque Standard, and ways that you can get involved in the process, including giving feedback. 

Obtaining stakeholder feedback is an essential process in revising the LEAF Marque Standard, and public consultation plays an important part. For the LEAF Marque Standard v17.0 Draft, two public consultations ran from 12 March 2024 to the 10 May 2024 and 1 October 2024 to 29 November 2024. For a synopsis of the feedback received and response by LEAF Marque, please see the Public Consultation Synopsis. We welcome feedback on the LEAF Marque Standard at any time, please get in touch with our team at [email protected].
