• Abstract:
  Eco-driving consists of using energy-efficient approaches to driving aimed at reducing
  
  fuel consumption and, ultimately, CO2 emissions. A previous study found that an EcoDrive
  
  informational campaign was effective at increasing the use of eco-driving behaviors, but only
  
  when employees perceived that their supervisor supported the program and when they were
  
  personally motivated to perform the eco-driving behaviors. In order to build upon the findings of
  
  our previous study, the present study focused on increasing the use of eco-driving behaviors
  
  through an informational eco-driving campaign combined with supervisor training to support the
  
  use of eco-driving practices.
  
  In this study we collected baseline measures of driving knowledge, attitudes, and
  
  behaviors from employees at three organizations, as well as follow-up data collected at two
  
  months (Time 2) and six months post-intervention (Time 3). Implementing a quasi-experimental
  
  design with a control group (informational campaign only) and an experimental group
  
  (informational campaign combined with supervisor training), we tested the incremental
  
  effectiveness of supervisor training compared to the effect of an informational campaign alone.
  
  In total, 19 supervisors received supervisor training (supervisor training group) and 10
  
  supervisors were provided with the informational campaign materials only (control group). We
  
  collected data from 144 unique participants across the three time points, and of these responses
  
  we were able to match responses for 50 participants from Time 1 to Time 2 and 48 from Time 1
  
  to Time 3. We were also able to match responses from 38 participants across all three time
  
  points; however, because our interest was in change from baseline, and in order to increase our
  
  statistical power, analyses were conducted comparing Time 1 to Time 2 and Time 1 to Time 3
  
  data. We assessed changes in self-reported knowledge, attitudes, and behaviors using mixedmethod
  
  ANOVAs to assess the within-person change across time points and compare the
  
  effectiveness of the intervention between the control and supervisor training groups.
  
  We found that, in general, participants reported using eco-driving behaviors more often in
  
  the follow-up surveys compared to baseline measures. However, we did not find direct support
  
  for the supervisor training intervention providing an incremental increase in eco-driving
  
  behaviors and attitudes compared to the informational campaign alone. On the other hand, we
  
  did find that supervisor support, frequency of communication about eco-driving, and the
  
  percentage of employees who viewed the EcoDrive materials were greater in the supervisor
  
  training group compared to the control group. Additionally, employees in the supervisor training
  
  group rated the EcoDrive materials as more useful compared to the control group.
  
  Based on these findings, the supervisor training seemed to be effective in improving
  
  indicators of supervisor support; however, it may be that our limited sample size did not allow us
  
  to find statistically significant differences between the two groups in eco-driving behaviors. In
  
  this report we discuss in more detail the basis for this study, the implementation of the
  
  intervention, the results, and potential explanations for our findings in order to inform future
  
  studies. We also provide a detailed account of the methodology used in this study.
