While individual multinational corporations may have a disproportionately negative impact on the environment, the cumulative effect of small and medium-sized enterprises (SMEs) also presents both a huge problem and an excellent opportunity for climate action. According to a recent study by the British Business Bank, SMEs are responsible for nearly 50% of all business-driven greenhouse gas emissions in the UK largely, in part, due to the use of inefficient internal and supply chain processes. Despite this, 76% of SMEs are yet to implement a decarbonisation strategy and according to another recent study by O2 and the British Chamber of Commerce (BCC), only one in ten are even measuring their carbon emissions.
