1. 11. Meaning and Action in Sustainability Science : Interpretive approaches for social-ecological systems research

   Författare :Simon West; Lisen Schultz; Lorrae van Kerkhoff; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Meaning; interpretive; social-ecological system; complexity; science-policy interface; transformation; sustainability science methodology; Sustainability Science; vetenskap om hållbar utveckling;

   Sammanfattning : Social-ecological systems research is interventionist by nature. As a subset of sustainability science, social-ecological systems research aims to generate knowledge and introduce concepts that will bring about transformation. Yet scientific concepts diverge in innumerable ways when they are put to work in the world. LÄS MER

3. 12. Managing high environmental performance? : Applying life cycle approaches and environmental certification tools in the building and real estate sectors

   Författare :Nils W. O. Brown; Tove Malmqvist; Peter Guthrie; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; Buildings; operational energy use; life cycle assessment; environmental certification; environmental assessment; renovation; strategy; design process; value creation; embodied environmental impacts; Planering och beslutsanalys; Planning and Decision Analysis;

   Sammanfattning : The main aim of this thesis is  to demonstrate and critically assess life cycle approaches’ and environmental certification (EC) tools’ potential for supporting decisions for improved environmental performance in the building and real estate sectors.Using life cycle approaches, the thesis shows that for new build and renovation cases aiming for low operational energy use that embodied global warming potential (GWP) due to material production can constitute a large portion of a building’s lifetime GWP.

4. 13. Toward a more sustainable food system using public procurement

   Författare :Elvira Molin; Anna Björklund; Skoglund Wilhelm; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; procurement; food; sustainability; criteria; Environmental Strategic Analysis; Miljöstrategisk analys;

   Sammanfattning : Around 30 % of today's anthropogenic greenhouse gas emissions originate from the food sector. Food production is the lead cause of deforestation, biodiversity loss, depletion of fish stocks, and scarcity of fresh water. LÄS MER

5. 14. Recycling plant nutrients from waste and by-products : a life cycle perspective

   Författare :Johanna Spångberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Chemical fertilisers contribute to greenhouse gas emissions, fossil fuel use, use of non-renewable phosphate rock and a flow of reactive nitrogen to the biosphere, exceeding the planetary boundaries. Recycling of plant nutrients from waste and by-products from society would reduce the use of chemical fertilisers. LÄS MER

7. 15. Circular Business Model Design : Business Opportunities from Retaining Value of Products and Materials

   Författare :Julia L.K. Nußholz; Internationella miljöinstitutet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Circular Economy; business model innovation; circular business model; Resource efficiency; Reuse; Life cycle management; Value creation; sustainability assessment; Circular business model tools;

   Sammanfattning : Today our economy is largely based on linear material flows, and many products, such as electronics, furniture,building materials and textiles, are discarded even when they could still be used. Without urgent action, globalwaste is expected to increase by 70% by 2060 and global materials use is expected to more than double. LÄS MER
