This report is presented as deliverable D2.3 of work package 2 of the Danube Air Nexus. It presents the results of an exploratory impact assessment of short-lived air pollutant emissions on human health, crop production and near-term climate with a focus on the Danube basin. We use a global reduced-form source receptor air quality model TM5-FASST and a recent global pollutant emission inventory (HTAP V2, 2014) to make an attribution by sector of the various impacts and to explore the challenges and opportunities for possible. Preliminary results show that trans-boundary pollution is significantly contributing to population exposure to PM2.5 in the Danube area. Dominating polluting sectors are residential sector and agriculture. We estimate that annually 170000 premature mortalities can be attributed to PM2.5 pollution in the Danube area, and annual crop losses add up to an economic value of nearly 1 billion US$. This analysis is a first step in a more detailed, country-wise analysis that will be carried out as a follow-up of this report, with an improved version of the model and specifically designed scenarios for the Danube Basin.JRC.H.2-Air and Climat
