100% mineral petrol
liquid oilDESNZ 2025 'Petrol (100% mineral petrol)' — petrol with no bioethanol content. The forecourt petrol most people buy is a blend (E5/E10); for that use the 'gasoline' entry, which carries DESNZ's 'Petrol (average biofuel blend)' figures. The two differ by roughly 3% per litre in CO2e, so the choice matters for reporting.
