Marshalls plc is positioning its 'Made in Britain' initiative as a core element of its net-zero roadmap, emphasising shorter supply chains and reduced carbon emissions from transport. The landscape and building materials supplier argues that domestic production cuts logistics-related CO2 while supporting local jobs. Critics, however, question whether the focus on provenance deflects from wider embodied carbon in manufacturing processes. For procurement teams and sustainability managers, the move highlights a growing tension: geographic sourcing alone does not guarantee lower overall environmental impact without transparent lifecycle data. Marshalls has yet to publish granular emissions figures comparing UK-made versus imported product lines.
