Sustainable City Charter

The Sustainable City Charter is a pledge for owners, managers and occupiers of non-domestic buildings in Westminster.

Current signatories

The charter now has 105 organisations as full signatories, with over 100 in the process of signing up. Signatories represent over 20% of non-domestic floor space across Westminster.  

Westminster City Council is also a participant of the Sustainable City Charter. 

Associate members 

If you are a small organisation with fewer than 10 FTE employees and are just getting started on your sustainability journey, then you can become an Associate Member of the Sustainable City Charter. Associate Members gain access to the charter network and resources without making the commitments of a full signatory.
