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].
