Heidi Barnard, Head of Sustainability at NHS Supply Chain, presents the organisation’s roadmap to Net Zero - with targets that go beyond UK government requirements. In her keynote at Procurement & Supply Chain LIVE: Sustainability, Barnard highlights that the overwhelming majority of NHS Supply Chain’s emissions fall under Scope 3, driven by its vast and diverse supplier network. To address this, she outlines the organisation’s strategic approach: “Buy less, buy better, buy different.” Key initiatives include the mandatory Evergreen supplier assessment to evaluate sustainability progress and a demand planning tool to support NHS trusts in reducing unnecessary procurement. Barnard underscores the importance of supplier engagement, innovation, and clear expectations in achieving long-term sustainability goals.
