  1. 1. Heritability of methane emission in Swedish Red cattle in northern Sweden

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Lucy Chipondoro; [2024]
    Nyckelord :methane emission; heritability; swedish Red cattle; dairy cow;

    Sammanfattning : Dairy cattle contribute a significant proportion of greenhouse gases (GHG), mainly methane (CH4), among other livestock species. Methane has a negative impact on climate; therefore, its reduction is a top priority for a sustainable dairy production system. LÄS MER

  3. 2. Is the EU ETS effective? Examining the impact of the EU ETS on methane emissions

    Kandidat-uppsats,

    Författare :Carl Otto Lindsjö; William Karlander; [2023-07-03]
    Nyckelord :;

    Sammanfattning : The European Union Emission Trading System (EU ETS) is the world's largest trading system for emissions. It has a crucial role to play in meeting the goals of the Paris Agreement. However, there has been debate over its effectiveness. This thesis examines how the EU ETS impacts methane emissions.

  4. 3. Utilization of Biomethane in Decarbonising India´s Energy Mix

    Master-uppsats, KTH/Energiteknik

    Författare :Niraj Ravindra Kunkulol; [2023]
    Nyckelord :Anaerobic digestion; biogas; biomethane; membrane filtration; pressure swing adsorption; Anaerob rötning; biogas; biometan; membranfiltrering; trycksvängadsorption;

    Sammanfattning : This thesis investigates the potential of biomethane production in India, the impact of its integration into the energy mix, and the corresponding Greenhouse Gases (GHG) emission and potential reduction. India, with its huge population and being an agriculturally rich country, produces gigantic amounts of biodegradable waste from various sources such as Municipal Solid Waste (MSW),agricultural waste, animal husbandry, sugar industry, etc. LÄS MER

  5. 4. Faktorer som påverkar livslängden hos svenska mjölkkor : effekter på metanutsläppen

    Kandidat-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Mikaela Walltin; [2023]
    Nyckelord :fertilitet; nkalvningsålder; kvigor; metan; mjölkkor; rekryteringsprocent;

    Sammanfattning : Livslängden hos svenska mjölkkor är idag relativt kort då faktorer som en hög rekryteringsprocent, låg fertilitet, sjukdomar och skador, låg mjölkavkastning, hög inkalvningsålder och en önskan om bättre genetiskt material i nästa generations kvigor spelar in. Alla dessa faktorer påverkar i sin tur metanutsläppen då en mjölkko som lever länge och bidrar till besättningen med sin mjölkavkastning har lägre metanutsläpp än en ko som lever kortare tid.

  7. 5. Towards more sustainable dietary choices: Strategies for change in the context of Lucerne, Switzerland

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :André Wismer; [2023]
    Nyckelord :consumer behaviour; food system; dietary choices; meat intake; Earth and Environmental Sciences;

    Sammanfattning : Switzerland's current food system is unsustainable and responsible for 25% of the country's environmental footprint. Half of the greenhouse gas emissions from the Swiss food system are caused by meat and dairy consumption. LÄS MER
