  1. 16. The Role of Transport Purchasing Companies in the Reduction of Freight Transport Emissions : The Opportunities and Barriers of Environmentally Friendly Freight Transport

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Alva Lundgren; Ellen Haavikko; [2023]
    Nyckelord :Freight transport; green logistics; environmentally friendly logistics; sustainable freight transport; voluntary environmental targets; corporate carbon strategies; transport purchasing companies; PESTEL-analysis; Godstransporter; grön logistik; miljövänlig logistik; hållbara godstransporter; frivilliga miljömål; företags koldioxidstrategier; transportinköpande företag; PESTEL-analys;

    Sammanfattning : The freight transport industry accounts for a large and, moreover, an increasing share of the global greenhouse gas emissions. Despite this, previous studies point to the fact that freight transport purchasing companies (TPCs) do not take sufficient action to reduce emissions from the freight transports they buy. LÄS MER

  3. 17. Leveraging green hydrogen to decarbonise the aviation industry : A case study on electrofuels in Sweden

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Jakob Bergene; Jonathan Bruchhausen; [2023]
    Nyckelord :Electrofuel; e-fuel; electrokerosene; e-kerosene; SAF; sustainable aviation fuel; sustainable aviation; complementarity formation mechanisms; technology value chains; TVC; Techno-economic analysis; TEA; Elektrobränsle; e-bränsle; elektrofotogen; e-fotogen; SAF; sustainable aviation fuel; sustainable aviation; komplementära formationsmekanismer; technology value chains; TVC; Techno-economic analysis; TEA;

    Sammanfattning : For the EU to reach its 2050 climate targets the aviation industry that is highly dependent on fossil fuels needs to drastically reduce its emissions. In the decarbonisation of the aviation industry drop-in sustainable aviation fuels (SAFs) have been identified as a promising solution to abate the industry’s emissions. LÄS MER

  4. 18. What is the feasibility of using Power Purchase Agreements as a green electricity sourcing method for a large industrial company? : A Case Study

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Oskar Andersson; Fredrik Lindblad; [2023]
    Nyckelord :Power Purchase Agreements; Sourcing; Industrial Company; Green Electricity; Renewable Energy; PPA; Power Purchase Agreement; Uppköp; Industriellt bolag; Grön elektricitet; Förnyelsebar energi; PPA;

    Sammanfattning : With the increasing volatility on electricity markets and a growing emphasis on sustainability, renewable electricity has gained significant attention from corporate entities seeking to secure their green energy supply. Among the various methods available for securing green electricity, one method on the rise is Power Purchase Agreements (PPA). LÄS MER

  5. 19. Treatment of Metals in Highway Runoff Water : Comparison of green infrastructures and filter material for stormwater treatment

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Fanny von Matérn; [2023]
