Air pollution


Significant problems

Current air pollution problems in Denmark include ultrafine particles in our cities, and nitrogen fallout in parts of our countryside and marine areas. On a worldwide level, the most serious problem is the emission of CO2 (carbon dioxide) and other greenhouse gases that can contribute to global warming.

Aarhus University’s contribution

We measure air pollution in Denmark and Greenland. We work with mathematical models that can describe how air pollutants are transported, converted and deposited. These models go into a level of detail that ranges from local pollution in a street to nationwide and global air pollution. We manage national Danish data reporting in accordance with international conventions such as the Climate Convention and the Geneva Convention on Long-Range Transboundary Air Pollution, as well as the European Union.

Over a period of many years, we have developed special expertise in combining measurements and model calculations to describe and assess air pollution and its impact on humans and nature.

Research into the air and emissions is mainly carried out at the Department of Environmental Science
