21. The Regulation of Global SOx Emissions from Ships: IMO proceedings 1988-2008
Sammanfattning : MARPOL Annex VI regulates air pollution from international shipping. Emissions of sulphur oxides (SOx) are regulated through a global limit for the sulphur content of bunker fuels (referred to as a global cap) as well as a stricter limit in particularly sensitive areas, referred to as SOx Emission Control Areas (SECAs).

22. Characteristics of Particulate Emissions from Low Temperature Combustion and Renewable Fuels : Aerosol Mass Spectrometry of Refractory Carbonaceous Particles
Sammanfattning : Particulate air pollution is one of the major causes of premature death in the world, and combustion-derived soot emissions contribute strongly to the particulate pollution to which humans are exposed. Black carbon (BC) is one such emission and denotes soot with strong light absorption in the ultraviolet to infrared spectrum. LÄS MER
23. Particle emissions from car brakes : The influence of contact conditions on the pad-to-rotor interface
Sammanfattning : Due to their adverse health effects emissions have been regulated for over three decades. Brake wear particulate matter is the most important non-exhaust source, however current knowledge is mainly limited to observational studies. LÄS MER
24. Characterization of the Combustion of Light Alcohols in CI Engines : Performance, Combustion Characteristics and Emissions
Sammanfattning : Alternative fuels for combustion engines are becoming increasingly popular as society is pushing to phase out fossil energy to reduce CO2 emissions. The compression ignition (CI) engine has a high overall efficiency which makes it a valuable option for the transport fleet, despite the well known NOx and soot pollutants it emits. LÄS MER
25. An evaluation of regional sustainability by analysing energy and carbon flows – A study of Jämtland, Sweden
Sammanfattning : Models showing the anthropogenic and natural flows of two sustainability indicators; carbon based GHG and energy (as work energy) have been made for the Swedish region Jämtland. The methodology used was inspired by the study sustainability analysis conducted on the small Danish island Samsø using the above two indicators. LÄS MER
