1. Research and reflections on European air pollution policy support models
Sammanfattning : European emissions to air of SO2, NOx, PM2.5, NH3 and NMVOC still today cause harm to human health and the environment. These pollutants are associated with the premature death of ~400 000 people annually in the EU (25 000 perished in traffic accidents 2017). Improvements are expected but problems will persist.

2. Isotope-based constraints on sources and processing of black carbon, carbon monoxide, and brown carbon in South Asia
Sammanfattning : The highly populated South Asian region is facing rapid economic growth and urbanization. Here, both climate- and health-affecting atmospheric agents such as light-absorbing aerosols black carbon (BC) and brown carbon (BrC), trace gas carbon monoxide (CO), are often found in relatively high levels compared to in other regions.

3. State Learning and Role Playing : International environmental cooperation in the Arctic Council
Sammanfattning : This study investigates state interaction as a social learning process, where the ultimate aim is to enhance an understanding on how states learn of environmental norms. An entry into the domain on such learning processes is offered through a Constructivist approach and more specifically through the employment of a role theoretical perspective; a role here is signified as a state's repertory of behavior and its social position within a group.

4. Formation and Transformation of Atmospheric Brown Carbon (BrC)
Sammanfattning : Atmospheric brown carbon (BrC) aerosol absorbs light in the UV-Vis spectrum and has poorly constrained but potentially large climate forcing impacts. Most current climate models lack detailed chemistry and interlinked properties of atmospheric BrC, that induce large uncertainties in radiative forcing predictions. LÄS MER
