Root Cause Analysis for Air Quality Measurement Results of the EU-Life-Project „CLean INland Shipping“ in NRW (Part 1)

Results for the Inland Port of Duisburg

For the EU project CLean INland SHipping, LANUV NRW has carried out intensive investigations on NO_X emissions from shipping traffic and port operations on the North Rhine-Westphalian section of the Rhine. Based on the results, air pollution (NO₂) in large inland ports can be better specified. In addition, new methods for recording NO_X emissions from moored and moving ships were developed. The results allow an improved analysis of the air pollution contributions of the different NO_X emission sources. Directly at the Rhine, the EU limit value of NO₂ (40 µg/m³, annual mean) was complied with. The contribution of shipping traffic to the air pollution in the residential areas of the cities along the Rhine is lower than assumed. A more detailed description of the aspects of the individual CLINSH activities from NRW can be found in the German or English language reports of the LANUV NRW [1a,b–6a,b].
