We are delighted to publish our new report "Sustainable Value: a common approach to the commercial benefits of sustainability in UK commercial real estate".

The report discusses some common sustainability features in UK commercial property and how they relate to property value. The aim of the paper is to suggest more common ways of identifying and reporting common sustainability features to promote alignment across AREF members and the wider UK commercial property market.  These include topics such as common approaches to the capex associated with ESG risks, the role of EPCs, regulations and green certifications.

AREF would like to thank Sam Carson and the Sustainability and Value Steering Group for all their hard work in bringing this report together. 

Watch the video below, where Sam Carson of CBRE, author of our report and the Chair of AREF's Sustainability and Value Steering Group, provides an overview of the report and some of the insightful discussions that were had in its development:
