As part of the development of the Handbook of Emission Factors for Road Transport (HBEFA), this report details three of the key work packages carried out for HBEFA 5.1:Update of the aging functions for the deterioration of exhaust aftertreatment systems and temperature influences.Development of Euro 7 emission models, derived from the latest Euro 6/VI emission models and their adaptation to the existing Euro 7 limits.Integration of additional relevant, non-regulated pollutants into HBEFA, namely formaldehyde, acetaldehyde, isocyanic acid, and nitric acid, based on measurements on Euro 6/VI vehicles and literature data.
