  2. 1. Aviation and the Environment- Evaluation of High Propulsive Efficiency Engines

    Author : Linda Larsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aircraft engine; Environment; Open rotor; Turbofan; Aviation;

    Abstract : There has been more than a tenfold increase in passenger kilometers traveled over the last 40 years. The highest rate of growth today is in developing countries such as China and India. These countries also have the two largest populations in the world. READ MORE

  4. 2. Light-Induced Routes to Sustainable Biocrudes for Fuels and Lubricant Oils

    Author : Leandro Cid Gomes; Henrik Ottosson; Norbert Hoffmann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aviation fuels; triplet sensitization; photoacid; renewable energy; photochemistry; Kemi; Chemistry;

    Abstract : Fossil-based hydrocarbons are at present the ideal compounds for jet fuels and lubricant oils, so their replacement by novel technologies is not easy. Instead, sustainable routes to hydrocarbons, such as sunlight-driven processes, are desired to reduce the environmental impact by the transport sector. READ MORE

  5. 3. Sustainable Surface Functionalization of Lightweight Materials : Cerium Oxide Nanoparticles Replacing Chromium in Anodic Coatings and Carbon Nanomaterials for Lightning Strike Protection

    Author : Thirza Poot; Kajsa Uvdal; Linnéa Selegård; Zhang-Jun Hu; Mats Eriksson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Aviation accounts for 2-3% of the carbon dioxide emitted globally. One way to reduce emissions is to develop and introduce sustainable, functional, lightweight materials and coatings that increase the lifetime and fuel efficiency of aircraft. READ MORE

  6. 4. Scaffolding for multistakeholder dialogue-based processes in strategic planning for transitioning to sustainable mobility

    Author : Varvara Nikulina; Henrik Ny; Göran Broman; Henrikke Baumann; Julio Soria-Lara; Blekinge Tekniska Högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sustainability; transdisciplinary; co-production of knowledge; mobility; strategic planning; facilitation; dialogue-based process; Strategic Sustainable Development; Strategisk hållbar utveckling;

    Abstract : There are numerous sustainability challenges related to mobility. One of the main challenges is the necessary reduction of greenhouse gas emissions. The transport sector is one of the main emitters. There are also challenges regarding accessibility, health, equity, and justice that need to be considered. READ MORE

  7. 5. Life cycle assessment of transport systems and transport infrastructure : Investigating methodological approaches and quantifying impacts at project and network levels

    Author : Carolina Liljenström; Anna Björklund; Susanna Toller; Rolf André Bohne; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Strategier för hållbar utveckling; Strategies for sustainable development;

    Abstract : Reducing greenhouse gas emissions from the transport sector is a key challenge to reach global climate targets and limit global warming to below 2 ºC. The use of life cycle assessment (LCA) may provide knowledge about the environmental impacts of transport systems so that emission reduction measures can be identified. READ MORE
