Market opportunities to decarbonise heavy duty vehicles using high blend renewable fuels

Background & Challenge

High blend renewable fuels such as biodiesel at blends above B20 and drop in fuels like hydrotreated vegetable oil and biomethane, have a key role to play in reducing the greenhouse gas emissions of heavy duty vehicles (buses, coach and trucks). HGVs are responsible for 20% of road transport GHG emissions, with long-haul trucks being one of hardest sectors to decarbonise. They additionally offer an opportunity for achieving the DfT’s RTFO 2032 renewable transport fuels target, and contributing to wider scale road transport decarbonisation over the next decade.


  • Provide an overview of the current UK high blend renewable fuel market
  • Examine the barriers and opportunities for adopting high blend renewable fuels in HDVs
  • Examine the contribution that high blend renewable fuels could make in reducing GHG emissions from HDVs in the 2020 to 2050 timeline
  • Identify interventions to accelerate the deployment of high blend renewable fuel, including national and local policy measures

Actions & Outputs

  • To engage with a variety of stakeholders including renewable fuel suppliers, OEMs, fleet operators, local authorities and trade associations
  • To produce a report which will be communicated to Government 

Project designed and managed by the Zemo Partnership Secretariat in collaboration with Fuels Working Group members
