1. 6. Koldioxidberäkningsverktyg som kan främja hållbara beteenden : Utveckling av ett användarvänligt verktyg för vägtransportens utsläpp

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

   Författare :Emmy Lindberg; [2023]
   Nyckelord :carbon dioxide calculation; road transport; carbon literacy; sustainable behaviours; koldioxidberäkning; vägtransport; koldioxidlitteracitet; hållbara beteenden;

   Sammanfattning : Att minska koldioxidutsläppen är en av vår tids stora utmaningar. Transportsektorn bidrar till ökade växthusgaser, en tredjedel av Sveriges territoriella utsläpp kommer från inrikes transporter och vägtransport ansvarar för majoriteten av utsläppen. LÄS MER

3. 7. Kartläggning & optimering av externa flöden ur ett hållbarhetsperspektiv : En fallstudie på Gestamp HardTech

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

   Författare :Malin Norgren; Elin Lindberg; [2023]
   Nyckelord :Sustainable transport; Vehicle emissions modeling; Truck emissions; Vessel emissions; Train emissions; Air pollution modeling; Future vehicles;

   Sammanfattning : In the pursuit of sustainable development, the transportation sector plays a crucial role by significantly contributing to greenhouse gas emissions. The purpose of this study is to examine how companies utilizing third-party logistics can compile and reduce transport-related emissions, more specifically investigating short- and long-term opportunities for the external flow of Gestamp HardTech in Luleå.
