Glossary of low carbon fuels terms launched

  • Developed by a group of trade bodies and key stakeholders, the glossary comprises 47 terms for liquid fuels, and 12 for gaseous fuels
  • The document will be continually updated to keep pace with the development of cleaner fuels and feedstocks
  • It can be found on

The decarbonisation of transport requires action on many fronts.  One of the most immediate ways of bringing down greenhouse gas emissions from road vehicles is replacing conventional fossil fuels with renewable and recycled carbon fuels.  There are many different low carbon fuels, and this glossary aims to bring clarity and widen understanding of the subject matter.

The trade bodies that have worked together to produce this document welcome its launch, and will publicise it among their members.

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, UKPIA said

“The launch of E10 has helped consumers become more familiar with what is going into their tank 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.”.

Andy Eastlake, Zemo Partnership’s Chief Executive, 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.”
