  2. 1. Income, Energy Taxation, and the Environment : An Econometric analysis

    Author : Tarek Ghalwash; Runar Brännlund; Pere Riera; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Household consumption; energy demand; emissions; rebound effect; energy taxation; tax elasticities Environmental services; income elasticities; Engel Curves; income distribution.; Economics; Nationalekonomi;

    Abstract : This thesis consists of four papers: two of them deal with the relationship between consumption, energy taxation, and emissions on macro level, and two of them focuses on the effects of changes in consumption and income on the environmental quality on a micro level. The main objective of paper [I] is to examine how exogenous technological progress, in terms of an increase in energy efficiency, affects consumption choice by Swedish households and thereby emissions of carbon dioxide (CO2), sulphur dioxide (SO2) and nitrogen oxide (NOx).

    Author : Magnus Christensen; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motorer; framdrivningssystem; Motors and propulsion systems; efficiency; emissions; combustion; HCCI; engine;

    Abstract : The potential and limitations of the Homogeneous Charge Compression Ignition (HCCI) engine concept has been experimentally investigated. The operation range, in terms of usable air/fuel ratio and engine load, and the emission characteristics have been studied. An 1. READ MORE

  5. 3. Biogas production from a systems analytical perspective

    Author : Maria Berglund; Miljö- och energisystem; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiforskning; Energy research; indirect environmental impact; fuel-cycle emissions; environmental systems analysis; energy systems analysis; energy balance; digestate; Anaerobic digestion; biogas;

    Abstract : Anaerobic digestion and the production of biogas can provide an efficient means of meeting several objectives concerning energy, environmental and waste management policy. Interest in biogas is increasing, and new facilities are being built. READ MORE

  6. 4. Indirect measurements for control and diagnostics of IC engines

    Author : Roger Johansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Abstract : The combustion process in internal combustion engines determines engine power, fuel consumption, exhaust emissions and combustion noise. Measurement and analysis of in-cylinder pressure plays an important role in the improvement and optimization of engine performance. READ MORE

  7. 5. Land use GHG emissions and mitigation options, simulated by CoupModel

    Author : Hongxing He; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; GHG; CO2; N2O; forest; drained peatland; clay soil; willow; soil nitrate leaching; modeling; CoupModel; GLUE; Land use; mitigation option; cost benefit analysis;

    Abstract : Climate change and greenhouse gas (GHG) emissions are one of the major challenges to the humankind of 21st Century. This thesis focuses on understanding, estimating and suggesting mitigation of the GHG emissions (mainly N2O and CO2) from the land use sector, specifically from forest ecosystems on drained peatlands but also from willow production on agricultural clay soil.
