In recent years, Glasgow has looked to move beyond its heavy manufacturing past towards a vision for a more sustainable, net-zero carbon future. The circular economy has been pivotal for this vision: it holds significant potential for climate mitigation and resilience. In light of the UN Climate Change Conference (COP26) and the ongoing drive for businesses, cities, and nations to reach ‘net-zero’, Glasgow is now looking to link its circularity ambitions with its carbon targets and to empower local businesses to effectively achieve both goals. This report, by Circle Economy and Glasgow Chamber of Commerce, aims to help Glasgow businesses understand the links between the adoption of circular strategies and business models and reaching net-zero carbon. It highlights key opportunities for businesses in five sectors—food and drink, textiles, manufacturing, events and conferences and the built environment—where circularity helps achieve net-zero carbon. It also outlines ways forward for Glasgow to effectively leverage and enable the circular opportunities identified, with a focus on safeguarding positive impacts for people and the planet.
