This study analyzes the environmental impact resulting from future trends in fleet composition and proposes an innovative vehicle classification system focused on raising consumer awareness of the importance of their choices with regard to key attributes such as body type, engine power and vehicle weight. A sensitivity analysis of the fleet's greenhouse gas emissions to deviations in their composition is carried out, considering the preferences expressed by the consumers in 2022 and the vehicle's specifications reported by the automotive industry on European digital platforms embodying Industry 4.0 principles. The findings show that internal combustion fleet emissions are expected to rise 0.30% per 1% increase in engine power and 0.44% to 0.69% per 1% increase in weight, according to the Worldwide Harmonised Light Vehicle Test Procedure (WLTP). The plug-in electric vehicle (PHEV) segment is the fastest growing in terms of market share. This trend will continue in the future, as this is the segment best suited to comply with the emissions targets imposed on manufacturers. Another relevant conclusion is that the environmental impact of PHEV vehicles is potentially very negative if the drivers' charging habits do not reflect the manufacturer's design intention. Thus, the development of consumer environmental awareness tools is urgent. This is the study's main motivation: to develop a tool in the scope of the Industry 4.0 while promoting the emergent concept of Industry 5.0, sustainability based and human-centered.121444727engEuro 7GHG emissionsIndusty 4.0PHEVSustainabilityvehicle databasevehicle fleetvehicle labelingWLTPGeneral Computer ScienceSDG 7 - Affordable and Clean EnergySDG 9 - Industry, Innovation, and InfrastructureSDG 13 - Climate Actionjournal article10.1016/j.procs.2024.01.144https://www.scopus.com/pages/publications/85189772294
