1. 16. Towards Sustainable Construction: Life Cycle Assessment of Railway Bridges

   Författare :Guangli Du; Raid Karoumi; Håkan Sundquist; Helge Brattebo; KTH; []
   Nyckelord :Life cycle assessment; LCA; Environment; Railway Bridge; Sustainability; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

   Sammanfattning : Since last few decades, the increased pressure from the environmental issues of natural resource depletion, global warming and air pollution have posed a great challenge worldwide. Among all the industrial fields, bridge infrastructures and their belonged construction sector contribute to a wide range of energy and raw materials consumptions, which is responsible for the most significant pollutions.

3. 17. Life Cycle Assessment of Present and Future Marine Fuels

   Författare :Selma Bengtsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA; marine fuels; environmental impact; LNG; biofuels; heavy fuel oil; Life Cycle Assessment; marine gas oil; liquefied natural gas;

   Sammanfattning : Interest in new fuels for marine propulsion is growing, mainly as a result of stricter environmental regulations but also due to increased attention to air pollution, greenhouse gas emissions and the uncertainty of future oil supply. Several different fuels and exhaust abatement technologies are proposed for marine transportation, all of which have different advantages and disadvantages in relation to the environment and human health.
