  1. 21. Consideration of life cycle energy use and greenhouse gas emissions for improved road infrastructure planning

    Författare :Sofiia Miliutenko; Anna Björklund; Jonas Åkerman; Annica Carlsson; Susanna Toller; Rolf André Bohne; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Greenhouse gas GHG emissions; energy use; life cycle assessment LCA ; road infrastructure planning; Planering och beslutsanalys; Planning and Decision Analysis;

    Sammanfattning : Global warming is one of the biggest challenges of our society. The road transport sector is responsible for a big share of Greenhouse Gas (GHG) emissions, which are considered to be the dominant cause of global warming. LÄS MER

  3. 22. Reducing greenhouse gas emissions – Examples from the freight transport sector: Essays on economic growth, public policy instruments, and renewable energy

    Författare :Johanna Takman; Johan Woxenius; Statens väg- och transportforskningsinstitut; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change mitigation; Renewable energy; Public policy instruments; Evaluation; Modal shift; Greenhouse gas emissions; Environmental Kuznets curve; Liquefied biogas; Economic development; Freight transport;

    Sammanfattning : The overall aim of this thesis is to improve the understanding of if, and how, we can combat climate change and other non-wanted environmental changes alongside economic development. Paper I address this question by investigating the relationship between CO2 emissions and GDP per capita. LÄS MER

  4. 23. Inertia and practice change related to greenhouse gas reduction : Essays on institutional entrepreneurship and translation in Swedish agri-food

    Författare :Herman Stål; Karl Johan Bonnedahl; Jessica Eriksson; Peter Dobers; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Inertia; climate change; sustainability; agriculture; institutional entrepreneurship; institutional logics; convergent change; divergent change; practice; translation; Tröghet; klimatförändring; hållbarhet; jordbruk; institutionellt entreprenörskap; institutionella logiker; konvergent förändring; divergent förändring; praktik; översättning; företagsekonomi; Business Studies;

    Sammanfattning : To avoid dangerous climate change a massive reduction in greenhouse gas emissions is required in a relative short time span. However, as development is moving in the wrong direction, there appears to be great inertia in changing activities. LÄS MER

  5. 24. Greenhouse gas emissions from cultivated peat soils in Sweden

    Författare :Örjan Berglund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Greenhouse gas emissions and peat subsidence are major concerns both from an environmental perspective and for farmers with declining soil production capacity. Agricultural databases, digitised maps of quaternary deposits and 40K radiation have been used in a GIS analysis to estimate the distribution and land use of agricultural organic soils in Sweden.

  7. 25. Greenhouse gas emissions from rewetted extracted peatlands in Sweden

    Författare :Sabine Jordan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Peat extraction for horticultural purposes and energy production has a long tradition in Northern Europe. Related drainage activities directly affect the greenhouse gas (GHG) balance due to oxidative peat decomposition and denitrification, with concomitant emissions of carbon dioxide (CO₂) and nitrous oxide (N₂O). Rewetting, i.e. LÄS MER
