Our commitment to sustainability

We are committed to fulfilling our purpose in a way that is environmentally, socially and ethically responsible. We are making Diploma an even better, safer and fairer place to work and we are working with our colleagues, suppliers and customers to deliver against our net zero targets. Our businesses deliver positive impact through products and services that benefit our society or environment.

Our framework 

Delivering Value Responsibly is our sustainability framework and part of our strategy. It focuses on our people, the environment and doing business responsibly. By bringing our existing and acquired businesses onto this framework we are able to accelerate their progress in these areas. Through training and engaging our businesses and colleagues, we are able to align the entire organisation to our sustainability goals.
