  5. 5. Environmental impact of a led fitting : A conducted life cycle analysis on a led fitting

    M1-uppsats, Jönköping University/JTH, Logistik och verksamhetsledning; Jönköping University/JTH, Logistik och verksamhetsledning

    Författare :Mika Fröjd; Evelina Skårhammar; [2020]
    Nyckelord :Sustainability; Environmental impact; LCA; led fitting; Life cycle; use phase; end of life phase; transportation; Carbon dioxide equivalent CO2e ;

    Sammanfattning : Purpose –The purpose of this research is to increase knowledge about how a led fitting impacts the environment. To be able to fulfil the purpose, it has been broken down into four research questions: • RQ1: What is the environmental impact during transportation? • RQ2: What is the environmental impact during the use phase? • RQ3: What is the environmental impact during the end of life phase? • RQ4: How can the environmental impact be decreased? Method: The authors worked abductive in the relation between theories and empirical data. LÄS MER
