Drivers for industrial energy efficiency are factors that promote the sustained adoption of energy-efficient measures and practices. Leveraging drivers to overcome barriers and encourage action which improves industrial energy efficiency can contribute to closing the energy efficiency gap. In fossil-fuel-based systems, this will also contribute to greenhouse gas abatement. A systematic literature review was used to investigate how knowledge about drivers is generated and whether prevalent drivers can be mapped to existing taxonomies. The systematic literature review confirmed that surveys and/or interviews with managers from countries who are members of the Organisation for Economic Cooperation and Development (OECD) are the most common way to gather data on drivers for industrial energy efficiency. This means the extant knowledge on drivers may be incomplete because contributions from some stakeholders, industry types and company sizes may be missing. The review also found economic drivers are the most prevalent and that not all the drivers identified during the study can be mapped to contemporary driver taxonomies. Having an agreed-upon comprehensive taxonomy facilitates empirical research and comparison of studies. Further research into the views of frontline workers and the creation of a comprehensive driver taxonomy is recommended. [ABSTRACT FROM AUTHOR]

Implementing energy efficiency measures is widely regarded as a high priority in the search for carbon dioxide emission reductions and can create competitive advantage for industry. Yet, approximately 50% of industry's cost effective energy efficiency measures are never implemented. The lack of implementation of energy efficiency measures results in the energy efficiency gap, which is generally attributed to barriers. Attempts to close the gap are directed at overcoming barriers and leveraging drivers. However, the current view of barriers and drivers may be incomplete due to the under representation of frontline workers' perspectives in research. Frontline workers strongly influence energy use because they make decisions about how and when industrial equipment is operated and maintained. This study compares survey responses from frontline workers and managers to investigate the barriers and drivers to industrial energy efficiency. Analysis of free text responses found perceived barriers and drivers for energy efficiency are different for frontline workers and managers. Differences between frontline workers' and managers' views are less prominent when only responses to Likert-type questions are considered. In response to this, new taxonomies for barriers and drivers were created. It is proposed these new taxonomies will be useful for empirical research as they can incorporate more complete views of frontline workers and managers. Common methods used to overcome barriers may have limited impact on the barriers found in this study. This more complete understanding of barriers and drivers could be useful for industry to characterise their challenges, contribute meaningfully to policy creation and generate new ways to close the energy efficiency gap. The novelty of this research stems from its investigation and presentation of the frontline workers' perspective. Further research into drivers, barriers and data gathering for frontline workers is needed to validate this exploratory study. • Frontline worker perspectives on barrier and drivers are presented. • Barriers and drivers for frontline workers and managers show some differences. • Common methods to overcome barriers may have limited impact on some of the barriers identified.
