1. 16. 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

3. 17. Improved environmental assessment in the development of wood-based products: Capturing impacts of forestry and uncertainties of future product systems

   Författare :Gustav A Sandin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; wood; water use; scenario modelling; land use; impact assessment; product development; environmental assessment; end-of-life modelling; sustainability assessment; forestry;

   Sammanfattning : The prospect of reducing environmental impacts is a key driver for the development of new wood-based products. But as wood-based products are not necessarily environmentally superior to non-wood alternatives, there is a need to assess the environmental impact of the product and guide the development process.

4. 18. 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. 19. Iodine Isotopes (129I and 127I) in the Baltic Sea   : Tracer applications & environmental impact

   Författare :Peng Yi; Ala Aldahan; Glen Snyder; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; radioactive 129I; stable 127I; AMS; iodine species; nuclear reprocessing facilities; tracers; Baltic Sea; circulation; water exchange; environmental impact;

   Sammanfattning : 129I is a radioactive isotope (T1/2= 15.7 million years) produced through natural and anthropogenic pathways, but the anthropogenic production is presently dominating the Earth’s surface environments. LÄS MER

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

   Författare :Anders Nordelöf; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
