11. Reducing Swedish Carbon Dioxide Emissions from the Basic Industry and Energy Utilities : An Actor and Policy Analysis
Sammanfattning : The aim of the thesis is to analyze the design of the present climate and energy policies. The main focus is on how the policy instruments affect the Swedish stakeholders who are included in the European Union’s Emission Trading Scheme (EU-ETS). LÄS MER
12. Air-Sea Fluxes of CO2 : Analysis Methods and Impact on Carbon Budget
Sammanfattning : Carbon dioxide (CO2) is an important greenhouse gas, and the atmospheric concentration of CO2 has increased by more than 100 ppm since prior to the industrial revolution. The global oceans are considered an important sink of atmospheric CO2, since approximately one third of the anthropogenic emissions are absorbed by the oceans. LÄS MER
13. Excess heat utilisation in oil refineries - CCS and algae-based biofuels
Sammanfattning : The main objective of this thesis is to investigate two different concepts for CO2 mitigation, from a system perspective, in relation to the oil refining industry: CO2 capture and storage; and algae-based biofuels. For all these processes, process integration with an oil refinery is assumed. LÄS MER
14. Carbon Credits: Origins, Effectiveness & Future
Sammanfattning : Carbon credits are used as an instrument for climate change mitigation. Each credit represents a reduction in greenhouse gas emissions (GHGs) equivalent of 1 ton of carbon dioxide. LÄS MER
15. Land-atmosphere interaction of a subarctic palsa mire
Sammanfattning : The main objective of this thesis was to quantitatively estimate the gaseous exchange of carbon dioxide (CO2) and methane (CH4) between a subarctic wetland ecosystem and the atmosphere. Additionally some initial estimates of the carbon input to the atmosphere of nonmethane hydrocarbons (NMHCs) were also obtained by combining different techniques in a joint setting. LÄS MER
