  2. 1. Carbon Emissions from Western Siberian Inland Waters

    Author : Svetlana Serikova; Jan Karlsson; Oleg S. Pokrovsky; Hjalmar Laudon; Peter Raymond; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; carbon; carbon dioxide; methane; carbon emissions; river; lake; inland waters; permafrost; Siberia; Limnology; limnologi;

    Abstract : Inland waters (i.e. rivers, streams, lakes, ponds) emit carbon (C) into the atmosphere. The magnitude of global inland water C emission has been estimated to equal the global ocean C sink, thus making inland waters an important component of the global C cycle. READ MORE

  4. 2. Carbon Dioxide in Inland Waters : Drivers and Mechanisms Across Spatial and Temporal Scales

    Author : Anna Cecilia Nydahl; Gesa A. Weyhenmeyer; Marguerite Xenopoulos; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon dioxide; dissolved organic carbon; inland water; lake; stream; groundwater; mesocosm; carbonate system; carbon; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Abstract : Inland waters are an essential component of the global carbon cycle as they are very active sites for carbon transformation processes. Much of this carbon is transformed into the greenhouse gas carbon dioxide (CO2) and emitted into the atmosphere. READ MORE

  5. 3. Decarbonization of construction supply chains - Achieving net-zero carbon emissions in the supply chains linked to the construction of buildings and transport infrastructure

    Author : Ida Karlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Embodied carbon; Buildings; Emissions reduction; Transport infrastructure; Scenario analysis; Low carbon technology; Carbon abatement; Decarbonization; Construction; Supply chain; Carbon mitigation;

    Abstract : Sweden has committed to reducing greenhouse gas (GHG) emissions to a net-zero level by Year 2045. In Sweden, about 20% of its annual CO2 emissions are from the manufacture, transport and processing of materials for both the construction and refurbishment of buildings and transport infrastructure.

  6. 4. An evaluation of regional sustainability by analysing energy and carbon flows – A study of Jämtland, Sweden

    Author : Torbjörn Skytt; Bengt-Gunnar Jonsson; Fredrik Ståhl; Magdalena Svanström; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Regional sustainability; Energy flows; Exergy; Carbon GHG fluxes; Sustainability indicators; carbon dioxide emissions; methane emissions; nature emissions;

    Abstract : Models showing the anthropogenic and natural flows of two sustainability indicators; carbon based GHG and energy (as work energy) have been made for the Swedish region Jämtland. The methodology used was inspired by the study sustainability analysis conducted on the small Danish island Samsø using the above two indicators. READ MORE

  7. 5. Traffic Emissions of Aerosols

    Author : Matthias Vogt; Douglas Nilsson; Eiko Nemitz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Primary Aerosol Emissions; Carbon Dioxide Emissions; Traffic Aerosol; Urban Aerosol; Traffic Activity; Emission Factors; Eddy Covariance; Aerosol Flux; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Non-exhaust traffic emissions are unregulated, yet the mass emission of non-exhaust particles may be larger than exhaust emissions. In addition, their emission factors (EF) are more uncertain than exhaust emissions. This thesis presents aerosol flux measurements in Stockholm using the eddy covariance method. READ MORE
