Our sustainability performance
The data tables below provide details of our latest performance against a series of key sustainability measures, as highlighted within our 2025 Sustainability Report.
These measures are presented within the ‘triple bottom line’ framework of People, Planet and Performance. They are monitored and reported to our Sustainability Committee on a quarterly basis to help accelerate our progress in delivering ‘more than energy from waste’.
