Under what conditions can a vehicle be counted as a green vehicle?

A vehicle can be counted as a green vehicle when it achieves a minimum green score of 45 on the ACEEE (American Council for an Energy-Efficient Economy) annual vehicle rating guide. This score is indicative of the vehicle's environmental performance, taking into consideration factors such as fuel economy, greenhouse gas emissions, and air pollution. The ACEEE rating is widely recognized and serves as a comprehensive measure of a vehicle's overall "greenness," providing a standardized assessment that helps consumers and organizations identify vehicles with lower environmental impacts.

While using alternative fuel sources, being an electric model, or just meeting the criteria for a low-emission vehicle contributes to overall sustainability, these factors alone may not guarantee that the vehicle meets the broader criteria set out in the ACEEE rankings. Therefore, the specific threshold of a minimum green score ensures that vehicles are evaluated consistently based on multiple environmental performance metrics, providing a more complete picture of their impact.
