    Abstract : Fuel combustion for transport was responsible for 24% of EU-28 greenhouse gas (GHG) emissions in 2016. Member states are expected to ensure that the share of renewable energy in the transport sector is at least 14% by 2030. Some countries, such as Sweden, have more ambitious targets. READ MORE

  4. 4. Promotion of sustainable renovation in the built environment : An early stage techno-economic approach

    Abstract : According to the Swedish Government's set targets for energy use and environmental quality imposed by the European Union, the total energy per heated unit area in residential and commercial buildings will have to be decreased by 20% in 2020 and 50% by 2050 in relation to the annual consumption of 1995. The building sector should additionally be completely independent of fossil fuels for energy usage, with the increasing sector of renewable energy continuously growing until 2020. READ MORE

  5. 5. Systems Analysis of Chemicals Production via Integrated Entrained Flow Biomass Gasification : Quantification and improvement of techno-economic performance

    Author : Jim Andersson; Luleå tekniska universitet; []
