Individual and contextual variables enhance transfer for a workplace eco-driving intervention

The adoption of energy efficient driving styles and practices, eco-driving, has been recognized in the literature as an option for reducing vehicle energy consumption. Prior eco-driving research has looked at the effectiveness of various eco-driving programs. However, the characteristics of the individuals participating in fleet eco-driving programs and the role of the supervisor as an advocate for eco-driving practices have remained relatively unexamined. An eco-driving intervention intended to increase eco-driving behaviors in a work organization was conducted with fleet drivers in three public organizations. Drawing from the workplace training literature, we hypothesized that employee eco-driving behaviors will increase after the implementation of an eco-driving intervention, but that these behaviors will be dependent on the participant's pre-intervention motivation and support from their supervisor for implementing eco-driving practices. Survey data were collected pre- and post-intervention from 51 fleet drivers (average age 45.3 and 33% female), and results indicate that the eco-driving intervention was effective when either high levels of pre-intervention motivation or supervisor support were present.
