This document summarizes a technology-business networking event focused on habitat, construction, architecture and ceramics. It discusses the AIRUSE project, which aims to provide authorities in Southern Europe with measures to reduce PM2.5 and PM10 concentrations. The project works to identify and quantify emission sources in cities like Barcelona, Porto, Florence and Athens, and develop corrective measures. It expects to help identify key emission sources, demonstrate effective mitigation strategies, and provide tools to reduce particulate levels and meet EU limits. The project has encountered challenges in obtaining specific emission data from industries and accurately assessing contributions from activities like biomass burning and traffic.
