Clean Vehicle Options

Advanced technology vehicles, including hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), electric vehicles (EVs), and fuel cell vehicles (FCVs), can be part of the solution to the energy and environmental problems facing both industrialized and developing countries today.

Using these vehicles results in greater vehicle fuel economy, which provides the following benefits:

  • Consumers save money on powering their vehicles
  • Countries reduce their oil dependence and vulnerability to market fluctuations and price shocks
  • Countries reduce their emissions of greenhouse gases (GHGs) and other air pollutants
  • The energy sustainability of today's transportation-dependent lifestyle is increased

These vehicles are becoming widely accepted by the public, with most major car manufacturers offering some type of EV model. Along with an increasing market acceptance, charging stations are being installed in large numbers to recharge vehicle batteries using electricity.

Rapid advances in energy storage technologies, specifically lithium-ion batteries, over the past decade have made market introduction of advanced, fuel-efficient vehicles possible. Research and development is ongoing, and hybrid and electric vehicles entering the market in two or three years will build upon the performance of today’s vehicles. Battery researchers are working to overcome the specific technical barriers of cost, performance, calendar life, and abuse tolerance.

With the increased focus on these technologies, the Implementing Agreement for co-operation for Hybrid and Electric Vehicles (IA-HEV) considers fostering policy discussions and information exchange on HEVs, PHEVs, EVs, batteries, and FCVs to be vital. Ongoing IA-HEV Tasks collect information on the numbers and types of PHEVs, EVs, and HEVs; technical specifications; government programmes to promote development; and the behavioral data of vehicle operators.
