Abstract: In recent years, the European Union has actively advocated for decarbonising hard-to-abate industries, including the glass sector. Stakeholders in both glass manufacturing and the research community have collaborated to fulfil ambitious CO 2 emission reduction objectives mandated by Brussels, in several ways. The initial strategic action to be undertaken involves reducing energy consumption through energy efficiency interventions; to achieve this goal, it is essential to be aware of own consumption indicators by comparing them with appropriate performance ones. There are not many updated references connected to real-world cases, nor are indicators specifically tied to individual phases of the production process available. After a brief presentation of the container glass sector, which is the most important subsector, in terms of production capacity in Italy and the EU and its production process, the manuscript describes a real and representative plant of the sector, which has made its data available anonymously. In this way, energy performance indices representative of a typical production of the sector have been defined: they are updated and more detailed than the ones available in the literature. This representation therefore constitutes a case study that is representative of the most common plant configuration in the hollow glass sector in the EU.
