  1. 1. Carbon Emissions from Western Siberian Inland Waters

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  3. 3. Remote Measurements of Ship Emissions

    Författare :Niklas Berg; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; airborne; Ship emissions; sulphur dioxide; nitrogen dioxide; DOAS; in situ measurements; carbon dioxide;

    Sammanfattning : The combustion of sulphur-containing fossil fuels gives rise to emissions of sulphurdioxide. Nitrogen oxides are also emitted when fuels are burned. The InternationalMaritime Organization (IMO) has ratified regulations regarding Sulphur Fuel Content(SFC) and NOx emissions from the shipping sector. LÄS MER

  4. 4. Essays on Energy and Climate Policy – Green Certificates, Emissions Trading and Electricity Prices

    Författare :Anna Widerberg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Attitudes; Carbon Dioxide; Carbon Intensity; Climate Change; Electricity; Electricity Prices; Emissions Trading; Emission Allowances; Environment; Fairness; GARCH models; Lyapunov Exponents; Market Structure; Personal Carbon Allowances; Public Opinion; Reconstructed Dynamics; Stability; Tradable Energy Quotas; Tradable Green Certificates; Volatility;

    Sammanfattning : Paper I: An Electricity Trading System with Tradable Green Certificates and CO₂-emission Allowances Combinations of various policy instruments to deal with the threat of climate change are used throughout the world. The aim of this article is to investigate an electricity market with two different policy instruments, Tradable Green Certificates (TGCs) and CO₂ emission allowances (an Emission Trading System, ETS).

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

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

    Sammanfattning : 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. LÄS MER
