Driver behavior has a significant impact on vehicle fuel economy and emissions. Eco-driving refers to anything a driver can do to improve on-road fuel economy. The most common strategy used to promote eco-driving is an in-vehicle display that provides the driver with feedback about their fuel efficiency, typically in real-time.

This policy brief summarizes findings from an extensive review and analysis of many studies of eco-driving feedback conducted to determine the average impact of feedback on fuel economy and improve understanding of what types of feedback are most effective. The study provides the most accurate estimate to-date of the average impact of in-vehicle feedback on fuel economy and summarizes the current state of knowledge regarding characteristics of eco-driving feedback interventions that determine effectiveness.
