Transport and Covid-19: responses and resources

Regulations and Standards for Clean Trucks and Buses

On the Right Track?

This report reviews progress on technical standards for heavy vehicles that could enable trucks and buses with zero or near-zero emissions. It focuses on plug-in and fuel cell electric vehicles that use technologies at the forefront of green and inclusive economic development. It includes information on technical standards on charging and refueling infrastructure, and identifies remaining barriers and opportunities for their future development. The report offers valuable insights for all stakeholders involved in the transition to carbon-free mobility and clean energy.

This report is part of the Decarbonising Transport initiative

Policy Insights

  • Ensure that vehicle safety regulations and standards for electric and hydrogen cover all classes of road vehicles and better differentiate between light and heavy vehicles.
  • Leverage the experience of international regulatory fora to extend the coverage of safety-related requirements to heavy electric vehicles.
  • Ensure that the scope of regulations on the safety of hydrogen-powered heavy vehicles addresses aspects that are currently not adequately considered.
  • Involve diverse transport and energy stakeholders in the development of charging standards for electric heavy vehicles.
  • Address missing elements in regulations and standards related to electric road systems.
  • Develop hydrogen refuelling protocols for heavy vehicles using gaseous storage at 70 MPa, new nozzles and instruments guaranteeing compliance with stringent fuel quality requirements.
  • Increase the focus of pre-normative research on the safe use of low- and zero emission vehicles with existing vehicle infrastructure, especially for hydrogen-powered options.
  • Harmonise regulations on tailpipe GHG emissions and energy consumption of heavy vehicles, also integrating instruments evaluating energy use for low- and zero-emission vehicles.
  • Fully integrate electricity and hydrogen into regulatory policies on low-carbon fuels.
  • Address non-regulated pollutants and integrate hydrogen-powered vehicles using internal combustion engines in regulations on tailpipe pollutant emissions.
  • Address the environmental performance of vehicle batteries with regulatory innovation targeting their durability, carbon footprint and the sustainability of associated supply chains.
  • Develop an internationally harmonised regulatory framework for the application of differentiated road charges and access restrictions based on environmental performances of vehicles.
