NILU's Environmental Management Report 2015. NILU OR
One of NILU's main goals is to study the impact of pollution and supply decision-makers with a sound scientific platform for choosing measures to reduce the negative impacts. Furthermore, it is very important for the institute to have control of the impact the institute¿s own activities may have on the environment and to reduce negative impacts as far as possible.
NILU has for many years been working to improve the status of the environment and to reduce negative impacts. In order to take this one step further, it was decided that the institute should restructure the work according to a relevant environmental standard and to seek certification according to the same standard.
The chosen standard is ISO 14001:2004 (Environmental management systems - Requirements with guidance for use) and NILU achieved certification according to this standard in October 2010. This report summarizes the results of the system in 2015.

SHIPMATE - Ship traffic particulate matter emissions. Final project report. NILU report
In the SHIPMATE project, we have carried out measurements of a large number of pollutants and aerosol components at the Mt. Zeppelin observatory during 2014 and 2015, with focus on the summer period (April to September). The aims were 1) identification of the particulate matter (PM) contribution from ship emissions by source apportionment and 2) isolation of data records influenced by local ship emissions in order to preserve the usefulness of the observatory for regional trends of atmospheric constituents. A total of 8 potentially ship-influenced 3-day sampling intervals were found in the analysis of the wind direction record and the harbour calls from Ny-Ålesund (2014 and 2015). The local shipping pollution contributed significantly (¿50%) to the concentration levels of certain heavy metals such as Cu, Ni, Zn and Cd during the two summers. This is supported by the enrichment factors analysis. However, the influence of local pollution from shipping on the measurements carried out at the Mt. Zeppelin observatory is rather infrequent.

Air quality in Ny-Ålesund. Monitoring of local air quality 2014-2015. NILU report
The concentrations of the measured components are generally low and below national limit values for the protection of human health and critical levels for the protection of vegetation.
Wind from northern sectors gave the highest average concentrations of nitrogen oxides, which indicates the power station and the harbour as possible sources. From September 2014 to February 2015, volcanic eruptions at Iceland emitted large volumes of SO2, which gave episodes of elevated concentrations in Ny-Ålesund. The measurement results for CO2 show an annual variation with higher concentrations in the winter and lower in summer. Measured concentrations of CO were most likely caused by local snowmobile traffic and long-range transport of emissions from wildfires in North America.
