We have been working to improve energy efficiency, reduce carbon emissions, minimise waste to landfill and cut water use for many years, reporting annually on our progress since 2002.
Our Sustainability Briefs and Supply Chain Charter set out our required standards and good practice examples where appropriate. Download our Briefs and Supply Chain Charter: Policies.
At our properties: We work closely with our site management, implementing environmental action plans at all major assets. We also work with occupiers to reduce energy use and cut carbon emissions, notably through sustainability groups in our multi-let offices. The main emissions at our properties where we have influence come from energy use. We have invested in automatic metering and energy monitoring across our portfolio in partnership with occupiers, so our property teams can identify ongoing reduction opportunities. We have also achieved culture change so all our building engineers now see efficiency as a core part of their jobs.
On our developments: We have been delivering our award-winning Sustainability Brief since 2011, improving construction site management, delivering efficient designs and enhancing biodiversity. We have created 4.3 million sq ft of BREEAM Excellent new offices and homes in London since 2009, with a further 1.7 million sq ft of space on track to achieve Excellent. This reflects our strong performance on efficiency, wellbeing, transport, materials, ecology and other sustainability criteria. The main emissions on our developments where we have influence come from embodied carbon. We have been working to improve understanding of embodied carbon since 2009, commissioning and publishing several studies. Building on this, we have been partnering with our supply chain to cut embodied carbon since 2011.
We have completed Energy Performance Certificate (EPC) assessments across our portfolio. Most of our office, retail and residential buildings significantly outperform the UK Government’s Minimum Energy Efficiency Standards. For those buildings rated F and G, we have plans in place to upgrade performance. We will not normally purchase assets with F or G ratings, without a clear asset plan to improve this rating.

We have also carried out flood risk assessments for our existing buildings. For the limited number of assets with high flood risks, we are working to mitigate these risks. We have also shared our findings with our insurer. We will carry out further flood risk assessments as appropriate.
Our business is focused on investment in existing towns and cities, which means we do not tend to build on greenfield or agricultural land, and that occasionally we must remediate previously contaminated land to make it suitable for new purposes and uses.
