    Abstract : There are a lot of uncertainties when it comes to global greenhouse gas (GHG) emissions which affects society’s ability to effectively respond to climate change. Small ponds have been found to potentially play a large role in global warming. READ MORE

  4. 8. A process to assess fossil-free transport transition pathways and develop a sustainability roadmap for transport purchasers

    University essay from Lunds universitet/Internationella miljöinstitutet

    Author : Lauren Brach; [2023]
    Keywords : Roadmap; corporate carbon strategy; decarbonisation; transportation; fossil-free; Earth and Environmental Sciences;

    Abstract : Most (93%) of the greenhouse gas emissions in the transport sector come from road traffic in Sweden which includes passenger and freight transport activity (Trafikverket, 2022). The aim of this thesis was to understand pathways that transport purchasers can pursue to reach the fossil-free transportation goals from manufacturing plant to customer and to develop a process for assessing a market and developing a roadmap for achieving fossil-free transportation.
