Modelling of local air quality

In order to develop climate-friendly cities and towns with clean air, we need a better understanding of how different sources contribute to air pollution and greenhouse gas emissions.

Modelling is an important tool for understanding more about how emissions from different sources disperse in the environment and contribute to the pollution levels in different parts of the city. Models can also be used to calculate how much harmful air pollution individuals are exposed to, and to predict what effect such measures as charging fees for using studded tyres or driving during rush hour, or reducing speed might have on local air quality.

In order to do air quality modelling, it is crucial to have a good overview of all the emission sources in the area for which we are going to calculate. It is important to know both the amount of emissions, and where and when the emissions take place.

NILU has extensive experience in acquiring knowledge about emissions from urban and industrial sources. We develop and use innovative methods to create quality-assured emission inventories used by national and local authorities. Good emission data are also crucial for calculating the effect of various measures to ensure good air quality.

NILU has extensive experience in carrying out emission mapping, calculating dispersion and developing air quality action plans for municipalities and industry.
