Not all diesel is created equal. As Australia moves toward lower-emission transport, fleet managers, sustainability teams, and procurement officers are increasingly encountering terms like "renewable diesel," "HVO," "biodiesel," and "SAF." These fuels can look identical in a tank but differ enormously in their chemistry, emissions profile, engine compatibility, and regulatory standing. Here is what you need to know.

Copenhagen, Heathrow, Dublin and Hong Kong Airports all cut diesel fleet emissions by up to 90% with HVO renewable diesel. In an industry where every single minute counts and costs - ground fleets are a significant addressable source of airport emissions and the solution is already here. No new vehicles. No downtime.

Both HVO and biodiesel have emerged as popular alternatives to traditional fossil fuels. While they share the common goal of reducing carbon emissions, there are significant differences between the two.
