16. 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
17. Land use GHG emissions and mitigation options, simulated by CoupModel
Sammanfattning : Climate change and greenhouse gas (GHG) emissions are one of the major challenges to the humankind of 21st Century. This thesis focuses on understanding, estimating and suggesting mitigation of the GHG emissions (mainly N2O and CO2) from the land use sector, specifically from forest ecosystems on drained peatlands but also from willow production on agricultural clay soil.

18. Opportunities for CO2 Reductions and CO2-Lean Energy Systems in Pulp and Paper Mills
Sammanfattning : The risk for climate change is a growing concern for theglobal society. According to what is known as the Kyoto Protocol,developed countries have committed themselves to reduce theirgreenhouse gas (GHG) emissions. The purpose of this thesis hasbeen to analyse opportunities for CO2 reductions in Swedish pulpand paper mills. LÄS MER
19. Economic growth, energy consumption and CO2 emissions in Sweden 1800-2000
Sammanfattning : Large transformations of technologies have occurred in the Swedish economy during the last two centuries, resulting in higher income, better quality of products and changing composition of GDP. An agrarian society has given way to an industrial society and lately to a post-industrial phase. LÄS MER
20. Hybrid Solvents based on Ionic Liquids/Deep Eutectic Solvents for CO2 Separation : Experiments, Modeling, Process Simulation and Evaluation
Sammanfattning : CO2 separation plays a vital role in reducing CO2 emissions to combat climate change, in which solvent-based absorption is widely considered the most promising technology. Many conventional chemical and physical solvents have been introduced for CO2 separation, still facing challenges. LÄS MER
