But do you have the time to trawl through 50 pages of policy? The standard was developed by an international committee of experts, of which I was leader of the UK delegation, and so, as I live and breathe sustainable procurement, here’s my golden principles: Sustainable procurement is good procurement. In order to do sustainable procurement well you need to do procurement well. If your organisation’s procurement practices are rubbish, your sustainable procurement will be rubbish, too. Call it what you like. The ISO committee comprising 50+ nations decided on the term Sustainable Procurement. There are lots of other terms such as; Responsible Sourcing, Ethical Procurement, Responsible Supply Chain Management, Green Buying, CSR in Procurement, Social Procurement and many, many more. It all adds up to the same thing. Call it whatever suits your organisation’s culture. Engage a wide range of people. This is not just something your purchasing department does on Wednesdays. Your strategy needs to apply to anybody in your organisation who participates in procurement decisions or works with suppliers. Have a policy. Yes, you will need a policy, but don’t sit in a darkened room and write one, or nick one from the internet. It takes time to bring your colleagues and suppliers along with you. There are many examples of good policies, you can find one here. Follow the Golden Thread. A good policy is essentially a translation of your organisation’s policy, in language your supply chain can respond to. There should be a golden thread between the two. Sustainable supply not sustainable supplier. Your strategy should aim to encourage your suppliers to contribute to your objectives, not necessarily to reward your suppliers for having great internal strategies. Prioritise, prioritise, prioritise. Not all of your categories of supply will contribute to all of your sustainability goals. Develop a priority heat map to focus your category managers on the issues that are meaningful to their suppliers. How far down the supply chain you look will depend on where the impact will be most significant. Support your people. Procurement professionals are integrators of other professions. A good sourcing exercise will engage a wide range of experts. Sustainability is no different, expert advice needs to be on tap for the procurement team, in addition to awareness and training. Develop your supply chain. Keep your supply chain competitive to quash the myth that sustainable procurement costs more. Invest in developing your suppliers’ competence. By only selecting the most sustainable, you will shrink your market and prices will go up. Do it for real. Your prioritisation exercise will throw up red impacts across your range of supply categories. Your team should be addressing these impacts every time they buy. Adopt the mantra “every red, for every purchase, every time” and you won’t go far wrong. Good luck with all that! For more information go to www.iso20400.org or contact Shaun.

Sarah Chatfield May 2026 Blog Comparing PAS 2080 vs the CO₂ Performance Ladder: What’s the Difference and How Do They Work Together? At a high level, the distinction is simple. PAS 2080 provides a framework on how carbon is reduced across projects and assets (delivery and design), while the CO₂ Performance Ladder focuses on how an organisation manages and evidences its energy consumption and carbon performance, and how organisations can certify and incentivise that performance through procurement.
