Sustainability East members come from the statutory, voluntary and private sector, bringing together a broad range of experience and expertise on environmental, social and economic issues.

Members join as individuals with an independent voice, not as representatives of their 'day job'. As a 'champion' of sustainable development each member promotes sustainability principles within their own sphere of influence. Their membership also provides an opportunity to engage with people from different sectors, share understanding and best practice, and help develop a consensus on the best way forward.

Membership is reviewed regularly to ensure an appropriate mix of experience and expertise and that it reflects the range of interests across the region.
