  1. 1. Land use GHG emissions and mitigation options, simulated by CoupModel

    Författare :Hongxing He; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; GHG; CO2; N2O; forest; drained peatland; clay soil; willow; soil nitrate leaching; modeling; CoupModel; GLUE; Land use; mitigation option; cost benefit analysis;

    Sammanfattning : Climate change and greenhouse gas (GHG) emissions are one of the major challenges to the humankind of 21st Century. This thesis focuses on understanding, estimating and suggesting mitigation of the GHG emissions (mainly N2O and CO2) from the land use sector, specifically from forest ecosystems on drained peatlands but also from willow production on agricultural clay soil.

  2. 2. Corporate and city GHG inventories : Impact on global CO2 emissionswhen considering electricity and CHP-based district heating

    Författare :Lena Nordenstam; Björn Karlsson; Louise Ödlund; Danica Djuric Ilic; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : One initiative to reduce greenhouse gas (GHG) emissions involves developing standards for GHG inventories. Companies and cities (regions) can use GHG inventories to compile and report their GHG emissions. LÄS MER

  3. 3. Forests and Greenhouse gases. Fluxes of CO2, CH4 and N2O from drained forests on organic soils

    Författare :Karin von Arnold; Leif Klemedtsson; Mats Nilsson; Björn Hånell; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Greenhouse gases; GHG; fluxes of CO2; CH4; drained forests; organic soils; Skogsbotanik; miljöaspekter; växthusgaser; Water in nature and society; Vatten i natur och samhälle;

    Sammanfattning : One of the largest environmental threats believed to be facing us today is global warming due to the accumulation of green house gases (GHG). The concentrations of GHG in the atmosphere are a result of the net strength of different sinks and sources. LÄS MER

  4. 4. Clean development Mechanism (CDM) Policy and Implementation in China

    Författare :Lei Zeng; Leif Gustavsson; Mälardalens högskola; []
    Nyckelord :Climate change; Clean development mechanism; CDM; CO2; Green House Gas; GHG; landfill gas; sustainable development; China; Energi- och miljöteknik;

    Sammanfattning : China is the second largest emitter of greenhouse gases (GHG) in the world. Since 68% of its primary energy is from coal, China’s average energy intensity is 7.5 times higher than the EU and 4.3 times higher than the US (EU, 2003). LÄS MER

  5. 5. Transition Technologies for Electrification and Optimisation of Bus Transport Systems

    Författare :Dennis Dreier; Viktoria Martin; Dilip Khatiwada; William Usher; Semida Silveira; Mark I. Howells; Hannah Daly; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bus transport system; C40; Decarbonization; Electrification; GHG; Optimization; OSeMOSYS-PuLP; Plug-in hybrid-electric; Systems analysis; Transformation; Busstransportsysstem; C40; Elektrifiering; Koldioxidminskning; Laddhybrid; Optimering; OSeMOSYS-PuLP; Systemanalys; Transformation; Växthusgaser; Energiteknik; Energy Technology;

    Sammanfattning : The topical issue of climate change has increasingly become important as scenarios indicate an increase of 2.5–7.8°C in the global mean temperature by the end of this century, if no greenhouse gas emissions are reduced. LÄS MER
