Greenergy is a British company that specializes in the supply, distribution, and blending of transportation fuels, including petrol, diesel, and biofuels. Founded in the 1990s, the company focuses on providing low-emission diesel to enhance air quality. It has expanded from a small start-up to an international fuel supplier, primarily operating in the UK, Ireland, and Canada.

The company manages the entire supply chain for fuels, from sourcing and importing to storage and distribution. Greenergy serves a diverse range of customers, including petrol stations, supermarkets, major oil companies, independent retailers, and commercial transport users. It operates fuel blending terminals in key locations and owns a significant biodiesel production facility in Immingham, England. In 2024, Greenergy was acquired by Trafigura, which has strengthened its position in the European fuel market and reinforced its commitment to sustainable fuel supply.
