  1. 1. Analysis of the US procedure for the fuel consumption and greenhouse gases certification of heavy duty vehicles

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Paolo Enrico Viotti; [2019]
    Nyckelord :;

    Sammanfattning : The vehicle sector is facing the biggest revolution of the last 70 years, whose main target is the depletion of emission and a steady decrease of fuel consumption. The focus in this report is the Green House Gas Emissions model (GEM) developed by the United States Environmental Protection Agency (EPA). LÄS MER

    Sammanfattning : This paper discusses the potential of gasoline, ethanol and methanol ternary blend as an alternative passenger car fuel in Sweden. Sweden has set various targets aimed to reduce its GHG emissions and to increase the share of renewables in the transportation sector. LÄS MER

  4. 3. Switching to the “Golden Age of Natural Gas” with a focus on shale gas exploitation : a possible bridge to mitigate climate change?

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Hossein Maazallahi; [2015]
    Nyckelord :Physical Geography and Ecosystem Science; GEM; shale gas exploitation; fugitive methane; climate change; carbon dioxide; age of natural gas; fossil fuel combustion; Earth and Environmental Sciences;

    Sammanfattning : Currently, policy makers put high attention in supplying global energy demand by focusing on 2°C policy; global temperature anomaly based on the global mean temperature of pre-industrial era (13.7°C). How to keep the 2°C policy at global scope is the main question in climate framework. LÄS MER

  5. 4. Assessing the Potential of Embedding Vegetation Dynamics into a Fire Behaviour Model : LPJ-GUESS-FARSITE

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Efren Lopez Blanco; [2014]
    Nyckelord :mediterranean ecosystem; LPJ-GUESS-FARSITE; FARSITE; fire modelling; fire behaviour prediction; dynamic fuel model; geography; fire recurrence; fuel loading; LPJ-GUESS-SPITFIRE; fuel moisture; physical geography; GEM; Earth and Environmental Sciences;

    Sammanfattning : Disturbances such as wildfires are key players involved in the shape, structure and function of the ecosystems. Fire is rarely included in Dynamic global vegetation models due to their difficulty in implementing its processes and impacts associated. LÄS MER

  7. 5. Life Cycle Assessment of Cruising Ship Superstructure

    Master-uppsats, Institutionen för geovetenskaper

    Författare :Qianqian Hou; [2011]
    Nyckelord :Sustainable development; Life cycle assessment; composite material; ship superstructure; environmental impacts;

    Sammanfattning : This thesis project was conducted to compare the environmental impacts between two types of material for a superstructure of cruising ship (Norwegian Gem) using life cycle assessment (LCA) methods. With the increasing price of industrial raw materials and finite resources, more and more corporations or manufacturers endeavor in seeking more economical materials and less environmental impacts within the ship building field.
