  1. 1. Towards empirically grounded guidance for resource efficiency: Applying, developing and synthesising environmental assessments

    Author : Daniel Böckin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Circular Business Models; guidelines; business models; synthesis; Life Cycle Assessment; decoupling; resource efficiency; 3D-printing; Circular Economy; waste hierarchy;

    Abstract : Numerous solutions have been proposed to mitigate environmental damage, including resource efficiency and the vision of circular economy. Suggested solutions are often formulated as guidelines and heuristics like in the EU waste hierarchy, so-called R-hierarchies for resource efficiency and various guidelines for circular business models.

  2. 2. Environmental Modelling : Learning from Uncertainty

    Author : John M. Juston; Per-Erik Jansson; Jens Christian Refsgaard; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Models; data; error; uncertainty; hydrology; soil carbon; wetlands; phosphorus;

    Abstract : Environmental models are important tools; however uncertainty is pervasive in the modeling process.   Current research has shown that under­standing and representing these uncertainties is critical when decisions are expected to be made from the modeling results. READ MORE

  3. 3. Simplifying complex models : Application of modeling tools in exposure assessment of organic pollutants

    Author : Emma Undeman; Michael McLachlan; Kathrin Fenner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mass balance model; environmental modeling; exposure modeling; bioaccumulation; organic contaminants; emission estimate; plant model; steady state; poly parameter linear free energy relationship; PPLFER; ecosystem susceptibility; Environmental chemistry; Miljökemi; Persistent organic compounds; Persistenta organiska föreningar; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Thousands of chemicals are used in society, but the exposure to humans and other organisms has been measured only for a small number of compounds. Modeling tools constitute low-cost and effective alternatives to measurements for the assessment of exposure. READ MORE

  4. 4. Biodiversity in environmental assessment : tools for impact prediction

    Author : Mikael Gontier; Berit Balfors; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Environmental impact assessment; Strategic environmental assessment; Biodiversity assessment; Prediction tools; GIS; GIS-base ecological models; Miljöteknik; Environmental engineering; Miljöteknik;

    Abstract : Urbanisation and infrastructure developments impact on the surrounding natural environment and threaten biodiversity. The fragmentation of natural habitats in particular is a major obstacle for the preservation of biodiversity in a long-term perspective. READ MORE

  5. 5. Using life cycle assessment to support the development of electrified road vehicles. Component data models, methodology recommendations and technology advice for minimizing environmental impact

    Author : Anders Nordelöf; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverter; magnet; LCI; electrical machine; stepwise improvements; electric vehicle; LCA; inventory data; motor; critical review; scalable model;

    Abstract : The anthropogenic pressure on the Earth system already overshoots safe limits for climate change, so there is an urgent need to drastically reduce greenhouse gas emissions caused by transportation. Electric propulsion technology is a promising solution that can decouple fossil fuel use from road vehicle traffic. READ MORE
