1. 1. Carbon allocation in aspen trees

   Författare :Sonja Viljamaa; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Trees allocate assimilated carbon between growth and storage. In this PhD thesis, Iinvestigated the regulation of carbon allocation during tree growth both attranscriptional as well as whole-tree level, and with a focus on wood formation. LÄS MER

3. 2. European Energy Policy in Transition: Critical Aspects of Emissions Trading

   Författare :Markus Wråke; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Energy policy; climate policy; carbon dioxide; climate change; emissions trading; EU ETS; efficiency; distributional effects; closures; new entrants; electricity; allocation; auctions; carbon leakage; competitiveness; peat; radiative forcing;

   Sammanfattning : The overarching theme of the thesis is European energy and climate policy, with a particular focus on the role of emissions trading. The thesis consists of eight papers. Paper 1 outlines the origins and characteristics of the European Union’s Emissions Trading System (EU ETS), launched in January 2005. LÄS MER

4. 3. Carbon sequestration processes in tropical seagrass beds

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

   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. 4. Instruments for reaching climate objectives. Focusing on the time aspects of bioenergy and allocation rules in the European Union's Emission Trading System

   Författare :Lars Zetterberg; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate Policy; Climate Impacts; European Union; Bioenergy; Forest residues; Carbon dioxide; Radiative Forcing; Peat; EU ETS; Emissions Trading; Allocation; Incentives; Benchmarking;

   Sammanfattning : The Europeans Union’s (EU’s) climate and energy strategy aims at reducing the emissions of greenhouse gases (GHG) by 20 % (compared to 1990) and to increase the share of renewable energy to 20 % by the year 2020. Increased use of bioenergy is considered key in these efforts. LÄS MER

7. 5. Partial CO2 capture to facilitate cost-efficient deployment of carbon capture and storage in process industries - Deliberations on process design, heat integration, and carbon allocation

   Författare :Max Biermann; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon allocation; Partial CO2 capture; process industry; techno-economic assessment; CCS; heat recovery; amine absorption;

   Sammanfattning : Climate change requires that all energy-related sectors reduce drastically their greenhouse gas (GHG) emissions, at a global rate of 1–2 GtCO2 per year, starting now. Process industries, such as the iron and steel, cement, petrochemical, and oil-refining industries, are inherently carbon-intensive, and carbon capture and storage (CCS) is one of the few options available to achieve the required deep reductions in carbon dioxide (CO2) emissions.
