  1. 1. Temporal and spatial trends of organohalogens in guillemot (Uria aalge) from North Western Europe

    Författare :Hrönn Jörundsdóttir; Åke Bergman; Derek Muir; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic; environmental; monitoring; pollution; time trends; spatial trends; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

    Sammanfattning : The Arctic and sub-Arctic region of the North Atlantic is a remote area, also in relations to environmental contaminants, such as POPs, BFRs and last but not least, PFCs. Both the BFRs and PFCs are considered emerging pollutants of significant environmental concern. LÄS MER

  3. 2. Impact of Digitalisation on Environmental Sustainability in Manufacturing Systems

    Författare :Xiaoxia Chen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; digitalisation; environmental impact; Industry 4.0; manufacturing; sustainability;

    Sammanfattning : Manufacturing companies are striving to improve productivity and reduce the environmental impacts of their activities. Meanwhile, digitalisation plays an important role in increasing productivity and has a profound impact on the environment of manufacturing systems. LÄS MER

  4. 3. Assessing design strategies for improved life cycle environmental performance of vehicles

    Författare :Sofia Poulikidou; Anna Björklund; Per Wennhage; Gregory Keoleian; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle design; Design strategies; Lightweight design; Electric vehicles; Design for Environment DfE ; DfE tools; Life cycle assessment LCA ; Simplified LCA; Composite materials; Planering och beslutsanalys; Planning and Decision Analysis;

    Sammanfattning : Vehicle manufactures have adopted different strategies for improving the environmental performance of their fleet including lightweight design and alternative drivetrains such as EVs. Both strategies reduce energy during use but may result in a relative increase of the impact during other stages. LÄS MER

  5. 4. Satellie Monitoring of Urban Growth and Indicator-based Assessment of Environmental Impact

    Författare :Dorothy Furberg; Yifang Ban; Margareta Ihse; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban growth; remote sensing; landcover classification; landscape metrics; environmental indicators; environmental impact; Greater Toronto Area; Stockholm; Shanghai;

    Sammanfattning : One of the major consequences of urbanization is the transformation of land surfaces from rural/natural environments to built-up land that supports diverse forms of human activity. These transformations impact the local geology, climate, hydrology, flora and fauna and human-life supporting ecosystem services in the region. LÄS MER

  7. 5. Foresight and Feedback: Monitoring and assessing the environmental implications of emerging technologies

    Författare :Duncan Kushnir; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; patent analysis; lithium; Foresight; topic model; monitoring; guidance; energy system; resource availability; environmental assessment;

    Sammanfattning : The magnitude of the change required to approach sustainability indicates an effort that will have to be sustained over decades, during which vast new technology systems will have to be developed and deployed. Yet technological development is a double edged sword, and these efforts will inevitably incur unintended consequences. LÄS MER
