Abstract

Energy efficiency is considered a priority because it is not only a management target for companies, but also an effective means for the government of Korea to reduce greenhouse gas emissions and implement carbon neutrality. For this, it is necessary to identify in detail drivers that have a positive impact on energy efficiency-related investments by companies and shift to the development of sophisticated policies that can promote these drivers. Under these circumstances, this study contributes to providing basic data that the government can use as reference data for developing policies to improve corporate energy efficiency by determining drivers that can lead to investments for improving energy efficiency at each stage of corporate decision-making. To this end, we first assumed the company’s decision-making process leading to energy efficiency investments and then selected drivers that have a positive effect on each stage following a literature review. Further, since the government is paying considerable attention to energy efficiency as a means of implementing carbon neutrality, we divided the responding companies on the survey into large emitters of GHGs and small emitters and analyzed the results. Additionally, to improve the reliability of the results, we calculated the relative importance of each driver by applying a fuzzy analytic hierarchy process. We found that an energy price-related driver is more important for large emitters of GHGs. By contrast, we found that small emitters of GHGs placed increased importance on energy audit-related driver, energy efficiency policy-related driver, and technology identification driver. This study provides a framework for the government to take more sophisticated approaches toward developing policies for corporate energy efficiency improvement by identifying drivers that have a positive impact on the implementation of energy efficiency investments at each stage of the corporate decision-making process.
