Abstract: In this paper, we scrutinise a sample from Taiwan's food industry, focusing specifically on the food processing companies that are publicly listed in the Taiwan region. Grounded on the foundation of the data envelopment analysis (DEA) model and employing data from 2016 to 2021, we embarked on an exploratory investigation into the energy-saving potential of Taiwan's food industry. Our findings led to several notable observations: 1) the bootstrap method can effectively correct the overestimations commonly found in DEA; 2) when aligned with sustainability reports, corrected efficiency values provide a glimpse into the nuances of energy efficiency utilisation; 3) government subsidies play a pivotal role in promoting energy conservation within the food processing industry; 4) establishing clear energy-saving objectives facilitates businesses in achieving tangible energy conservation outcomes; 5) translating energy-saving potentials into equivalent energy data assists corporations and the government in strategic planning.

Keywords: sustainability report; data envelopment analysis; DEA; bootstrap; Taiwan.
