Our strategy supports our businesses in delivering their value-add missions. We’re also an agent of change – guiding small and mid-sized businesses through the unfamiliar territory of environmental and social responsibility, while building safer, more efficient and trusted businesses that do what’s right for people, the planet and society.

Our Delivering Value Responsibly (DVR) framework focuses on three themes through which we can have a meaningful impact. Discover how we’re delivering value for all our stakeholders.

Our All Stars programme has become a powerful platform to celebrate achievements, share success stories and strengthen our culture of appreciation and collaboration.

Our focus on supplier engagement to encourage responsible and sustainable action aims to accelerate reductions, enhance resilience and build greater transparency across the supply chain.

Our Stand up for Safety programme has continued to make positive progress and drive one consistent approach to health and safety across all businesses.

76% of Diploma businesses now send less than 15% of their waste to landfill.

Our partnership with Ecovadis is accelerating our ability to better engage with suppliers and enabling improved access to Scope 3 data across our value chain.

A shared framework locally led

Every Diploma business is unique. Our DVR framework supports our business strategy and commercial and operational activities. This shared framework empowers local teams to lead the change, backed by the tools and guidance they need. It’s the balance of independence and support that makes our model powerful.
