  1. 11. Tradeoffs between self and environment in environmental judgment and decision making

    Författare :Hanna Andersson; Patrik Sörqvist; Ulla Ahonen-Jonnarth; Fredrik Bökman; Marita Wallhagen; Lars-Olof Johansson; Högskolan i Gävle; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; tradeoff; environmental concern; anchoring effect; normative message; travel time; avvägning; miljöoro; förankringseffekt; normativt budskap; restid; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : One of the greatest challenges of today is to change our behavior to act more pro-environmentally to reduce global warming. We need to make sacrifices for the environment, e.g., use a means of transportation that take a longer time but causes less CO2 emission. LÄS MER

  3. 12. Life-Cycle Energy and Carbon Implications of Wood-Based Products and Construction

    Författare :Roger Sathre; Leif Gustavsson; Birger Solberg; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest products; climate change mitigation; carbon balance; energy; life cycle; wood; land use; Environmental engineering; Miljöteknik;

    Sammanfattning : Forests can be an important element of an overall strategy to limit the atmospheric concentration of carbon dioxide (CO2) that contributes to climate change. As an integral part of the global carbon cycle, forests remove CO2 from the atmosphere as they grow, and accumulate carbon in tree biomass. LÄS MER

  4. 13. Truck tyre rolling resistance : Experimental testing and constitutive modelling of tyres

    Författare :Jukka Hyttinen; Lars Drugge; Jenny Jerrelind; James Busfield; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Truck tyre; PRF; filler reinforced rubber; ambient temperature; rubber testing; parametrisation; Finite-element simulation; Lastbildäck; PRF; gummi; förstärkande fyllmedel; effekt av omgivningstemperatur; gummiprovning; parametrisering; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Global warming sets a high demand to reduce the CO2 emissions of vehicles. In the European Union heavy-duty road transports account for 6 % of the total greenhouse gases and one of the main factors affecting these emissions is related to the rolling resistance of tyres.

  5. 14. Investments, system dynamics, energy management and policy : a solution to the metric problem of bottom-up supply curves

    Författare :Fabian Levihn; Cali Nuur; Henrik Blomgen; Filip Johnsson; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Investments; Energy Management; Policy; MACC; CSC climate change abatement; energy efficiency and conservation; system dynamics; Industriell ekonomi och organisation; Industrial Engineering and Management;

    Sammanfattning : Today, issues such as climate change and increased competition for scarce resources puts pressure on society and firms to transform. Change is not easily managed though, especially not when relating to production or consumption of energy carriers such as district heating or electric power. LÄS MER

  7. 15. Energy systems analysis of Swedish pulp and paper industries from a regional cooperation perspective : Case study modeling and optimization

    Författare :Sofia Klugman; Bahram Moshfegh; Thore Berntsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial energy system; Optimization; District heating; Energy audit; Co-operation; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The industrial sector uses about one third of the energy end-use in the world. Since energy use in many cases highly affects both the local and global environment negatively, it is of common interest to increase energy efficiency within industries. LÄS MER
