  1. 1. Decarbonization of construction supply chains - Achieving net-zero carbon emissions in the supply chains linked to the construction of buildings and transport infrastructure

    Författare :Ida Karlsson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Emissions reduction; Low carbon technology; Transport infrastructure; Carbon abatement; Decarbonization; Supply chain; Scenario analysis; Carbon mitigation; Buildings; Embodied carbon; Construction;

    Sammanfattning : Sweden has committed to reducing greenhouse gas (GHG) emissions to a net-zero level by Year 2045. In Sweden, about 20% of its annual CO2 emissions are from the manufacture, transport and processing of materials for both the construction and refurbishment of buildings and transport infrastructure.

  2. 2. Climate change mitigation in China

    Författare :Bo Xu; Ronald Wennersten; Kerstin Kuchta; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; China; Climate change mitigation; Environmental Kuznets Curve EKC hypothesis; Mitigation target; Business-as-usual BAU scenarios; Policy instruments;

    Sammanfattning : China has been experiencing great economic development and fast urbanisation since its reforms and opening-up policy in 1978. However, these changes are reliant on consumption of primary energy, especially coal, characterised by high pollution and low efficiency. LÄS MER

  3. 3. Reducing Carbon Dioxide Emissions from the EU Power and Industry Sectors - An assessment of key technologies and measures

    Författare :Johan Rootzén; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industry; carbon dioxide; cement; European Union; technologies; emission reductions; CCS; power; steel; CO2; refining; mitigation;

    Sammanfattning : In February 2011, the European Council reconfirmed the goal of reducing EU greenhouse gas emissions by at least 80% by 2050, as compared to the levels in 1990. The power and industrial sectors currently account for almost half of the total GHG emissions in the EU. LÄS MER

  4. 4. Carbon sequestration processes in tropical seagrass beds

    Författare :Liberatus Dominick Lyimo; Mats Björk; Martin Gullström; Mariam Hamis; Teresa Alcoverro; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Seagrass; Carbon sequestration; Carbon sink; Eutrophication; Productivity; Nitrous oxide; Methane; Greenhouse gases; Tropical; Eastern Africa; växtfysiologi; Plant Physiology;

    Sammanfattning : Seagrass meadows may play a substantial role in climate change mitigation as they are capable to sequester and store substantial amounts of anthropogenic carbon in plant biomass and, more importantly, in their underlying sediments. In this PhD thesis, the carbon-burial potential was assessed by quantifying the amount of organic carbon stored in different seagrass meadows, each dominated by one of the four major seagrass species in the Western Indian Ocean region.

  5. 5. Kolets återkomst : Koldioxidavskiljning och lagring i vetenskap och politik

    Författare :Anders Hansson; Jonas Anshelm; Mats Westermark; Alf Hornborg; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Carbon capture; carbon storage; coal power; CCS; energy politics; climate politics; scenario; ecological modernization; Koldioxidavskiljning; koldioxidlagring; kolkraft; CCS; ekologisk modernisering; energipolitik; klimatpolitik; scenario; Technology and social change; Teknik och social förändring;

    Sammanfattning : I denna avhandling studeras en ny teknik för att hantera växthuseffekten. Den nya tekniken heter koldioxidavskiljning och lagring (CCS) och granskades av FN:s klimatpanel 2005 och tillskrevs då möjligheterna att stå för 15-55% av alla CO2-reducering fram till 2100 och detta till en 30% lägre kostnad än vad som annars vore möjligt.
