  2. 1. 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.

  4. 2. Essays on Energy and Climate Policy – Green Certificates, Emissions Trading and Electricity Prices

    Author : Anna Widerberg; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Attitudes; Carbon Dioxide; Carbon Intensity; Climate Change; Electricity; Electricity Prices; Emissions Trading; Emission Allowances; Environment; Fairness; GARCH models; Lyapunov Exponents; Market Structure; Personal Carbon Allowances; Public Opinion; Reconstructed Dynamics; Stability; Tradable Energy Quotas; Tradable Green Certificates; Volatility;

    Abstract : Paper I: An Electricity Trading System with Tradable Green Certificates and CO₂-emission Allowances Combinations of various policy instruments to deal with the threat of climate change are used throughout the world. The aim of this article is to investigate an electricity market with two different policy instruments, Tradable Green Certificates (TGCs) and CO₂ emission allowances (an Emission Trading System, ETS).

  5. 3. European ecosystems on a changing planet : Integrating climate change and land-use intensity data

    Author : Jan Hendrik Blanke; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LPJ-GUESS; land-use intensity; climate change; carbon; nitrogen; ecosystem functions; trade-offs; vegetation;

    Abstract : Dynamic global vegetation models are mathematical models that provide a bottom-up description of plant communities. They explicitly model physiological and population-level processes such as growth, photosynthesis, carbon allocation, regeneration and mortality. READ MORE

  6. 4. A spectroscopic study of polymer : Carbon nanotube composites

    Author : Andreas Müller; Ove Andersson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : Since the identification of carbon nanotubes (CNTs) by Ijima in 1991, this material has become a subject of great interest and effort in science because of the outstanding physical properties it exhibits. CNTs can be thought of as graphene sheets rolled into seamless cylinders of various diameters and in principle infinite length. READ MORE

  7. 5. Fabrication and Characterization of Composite TiO2/Carbon Nanofilms with Enhanced Photocatalytic Activity

    Author : Raja Sellappan; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TiO2; carbon; photoluminescence; photodegradation; recombination.; Photocatalysis;

    Abstract : The work presented in this thesis is dedicated to fabrication and characterization of an efficient thin film photocatalyst for environmental cleaning and solar fuel applications. Because of its simplicity and reproducible fabrication, the chosen combination of nanometer thin titania and carbon films serves also as a model system for a wider class of photoactive materials.
