Switching from fossil diesel to HVO renewable diesel achieves real emissions reductions across Scope 1 and 3 without changing vehicles, engines, or infrastructure. This practical guide breaks down exactly what changes and what stays the same for NGER auditors, sustainability leads, and operators. Understand the lifecycle impacts, measurement frameworks, and compliance benefits to confidently decarbonise today.

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.
