To mitigate transport emissions and their environmental consequences, collaborative and timely efforts are essential. Fine particle emissions and the formation of secondary aerosols significantly impact public health, yet their atmospheric behaviour remains incompletely understood.

The EU- and UKRI-funded AEROSOLS project seeks to address this gap by developing reliable methods for measuring and modelling currently overlooked volatile and semi-volatile primary and secondary emissions from vehicles, under real driving emissions (RDE) conditions. In addition, the formation of secondary aerosols and their atmospheric evolution are investigated. These primary and secondary emissions are categorised based on their environmental, health, and social impacts. AEROSOLS will propose technological and legislative solutions to control these emissions, enhancing air quality and public health.
