2. 1. Particle Emissions from Ships

   Author : Maria Zetterdahl; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LNG; marine fuel; fuel sulphur content; particle emission; sulphur emission control area; aromatics; SECA; heavy fuel oil; marine diesel oil; liquefied natural gas; ship emission;

   Abstract : Since 1st of January 2015 ships operating in sulphur emission control areas (SECAs) have to use marine fuels with a fuel sulphur content less than 0.1 %m/m. This regulation forces the ship owners to make a fuel shift and use low-sulphur marine fuel oils, use alternative fuels or use scrubbers on-board their ships. READ MORE

4. 2. Possibilities of CO2 emission reduction : process integration analysis and carbon trading schemes

   Author : Chuan Wang; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

   Abstract : Climate change is one of the greatest challenges faced by today's society. With more evidence from scientists, the need to manage greenhouse gas emissions has been increasing in response to international climate change negotiations. READ MORE

5. 3. Four Essays on Technology, Productivity and Environment

   Author : Jan Larsson; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; BAT; DEA; Dynamic factor demand; Efficiency; Emission; Environmental regulation; Multiproduct symmetric generalized McFadden cost function; Malmquist index; Mexico; NAFTA; Norwegian manufacturing; Productivity; Trade liberalisation;

   Abstract : The main subject of this thesis is the relationship between economic growth and environmental effects when the interaction between firms' behaviour and regulations are taken into account. In the first three papers I discuss different aspects of the relationship between regulations and environmental effects. READ MORE

6. 4. Green consumption energy use and carbon dioxide emission

   Author : Eva Alfredsson; Einar Holm; Neil Swan; Kerstin Westin; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic geography; Energy consumption; Carbon dioxide emission; Energy intensity; Carbon intensity; Life cycle assessment; Consumption patterns; Lifestyles; Systems analysis; Microsimulation modelling; Demography; Sustainability; Rebound effects; Substitution effects; Kulturgeografi; Human geography; Kulturgeografi; Social and Economic Geography; kulturgeografi;

   Abstract : The aim of this thesis is to explore the quantitative potential to reduce energy requirements and CO2 emissions through changed patterns of consumption, given unchanged levels of consumption expenditure. The thesis question is analysed using a systems analysis approach which in this case means that life cycle assessment data on energy requirements and CO2 emissions related to household consumption are combined with a financial and behavioural analysis to make sure that the budget constraint is kept and that both the first and second order effects of adopting a green consumption pattern are analysed.

7. 5. Catalytic Emission Abatement and Gas Separation

   Author : Martin Petersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NOx reduction; Ozone promotion; Flow reactor studies; Propane oxidation; Molecular simulations; Sulfur dioxide promotion; Zeolite adsorption; Environmental heterogeneous catalysis; Mean-field kinetic modeling; CO oxidation;

   Abstract : Air pollution is still today a major health problem. Emissions from mobile and stationary sources are regulated, but economical considerations limit the implementation of the most efficient abatement systems. To improve urban air quality, there is therefore a need to develop simple, durable and cost efficient emission control methods. READ MORE
