  1. 1. Research and reflections on European air pollution policy support models

    Författare :Stefan Åström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Economic perspectives; Decomposition analysis; Policy support modelling; Short-lived Climate Pollutants; Climate metrics; Air pollution; International shipping; Economic methodology; Integrated assessment modelling; Cost-benefit analysis;

    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.

  3. 2. Isotope-based constraints on sources and processing of black carbon, carbon monoxide, and brown carbon in South Asia

    Författare :Sanjeev Dasari; Örjan Gustafsson; August Andersson; Jos Lelieveld; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; South Asia; Air Pollution; Short-Lived Pollutants; Atmospheric Abundance; Model-Observation Mismatch; Radiocarbon; Stable Isotopes; Applied Environmental Science; tillämpad miljövetenskap;

    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.

  4. 3. State Learning and Role Playing : International environmental cooperation in the Arctic Council

    Författare :Sandra Engstrand; Monica Tennberg; Statsvetenskapliga institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Learning; international cooperation; role theory; arguing; symbolic interactionism; environmental norms; the Arctic Council; the Arctic; International relation IR ; International cooperation;

    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.

  5. 4. Formation and Transformation of Atmospheric Brown Carbon (BrC)

    Författare :Kalyan Mitra; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; brown carbon BrC ; primary organic aerosol POA ; secondary organic aerosol SOA ; BrC bleaching; BrC browning; Toluene photo-oxidation; NOx; Ammonia; NH3; acidity effects; light absorption;

    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
