The overall aim of the Green Vehicle Index project is to orient the consumer towards the most energy efficient low polluting vehicle by providing understandable information and to spark competition among manufacturers to produce real clean and energy efficient vehicles. In order to achieve this goal the following objectives have been defined:

  1. To define a holistic scoring mechanism and independent rating system for light duty vehicle’s environmental performance over the vehicle’s useful life defined as a 5-star rating system. Providing clear information to the consumer, enabling them to make an informed purchasing decision. The weighting criteria will take into account the wishes of end-consumers, which will be defined by a survey in 6 different countries.
  2. To develop a testing program for the assessment of vehicles, its sustainability by closing existing gaps and developing procedures beyond the state of the art. The GVI project will develop and update existing testing procedures to assess vehicle emissions including unregulated pollutants as well as assessing vehicle energy efficiency under real-world conditions, and providing independent and reliable test results.
  3. To demonstrate, verify and validate the overall scoring methodology and testing procedures by testing 49 market representative vehicles.
  4. To create the structure and appropriate instruments to economically self-sustain the program and sparking competition and innovation within the European automotive industry in the field of environmental performance. In this sense the GVI project plans to:
    1. define a complete roadmap to 2030 for the assessment program (Green NCAP). The roadmap will provide guidance on how to complement and extent the program. Some of the aspects that will be considered are: availability of upcoming measurement equipment, well-to-wheel emissions and energy efficiency, alternative propulsion systems, online consumer platform and implementation of the program in other markets;
    2. be fully transparent with respect to the test procedures, rating system and test results This transparency is applied among others for manufacturers to compare the environmental performance of their vehicles in detail and to help set the benchmark;
    3. provide incentives for test equipment manufacturers to introduce innovative measurement equipment on the market faster compared to conventional introduction of state-of-the-art test equipment driven by legislation.
  5. To provide recommendations based on gaps identified and on the validated results to rule makers to enable the update of future regulations on vehicle environmental performance;
