The RTFA (Renewable Transport Fuel Association) has published a glossary of low-carbon fuel terms to help bring clarity to and widen understanding of the fuels.

Developed by a group of trade bodies and key stakeholders, including UKPIA, the SMMT (Society of Motor Manufacturers and Traders) and the Zemo Partnership, the glossary comprises 47 terms for liquid fuels and 12 for gaseous fuels. It can be found at and will be continually updated to keep pace with the development of cleaner fuels and feedstocks.

Gaynor Hartnell, chief executive of the RTFA, said: “If we are to communicate the numerous benefits of the fuels our members produce, it’s imperative that people understand what we’re talking about.”

Chris Gould, energy transition lead at UKPIA, said: “The launch of E10 has helped consumers become more familiar with what is going into their tanks and as companies continue to reduce the carbon intensity of our fuels, having a common set of clear terms can help everyone understand what their fuels are and how they are reducing emissions.”

The Zemo Partnership exists to accelerate transport to zero emissions. Its chief executive, Andy Eastlake, said: “Renewable, low carbon fuels have a critical role to play in the UK’s transition to net zero. Clear and consistent communication is a vital building block, so we are very pleased to have contributed to this glossary which will help to raise awareness and improve understanding about renewable fuels.”
