11. Making the Transition to a ‘Green’ Vehicle Fleet : An analysis of the choice and usage effects of incentivising the adoption of low-emission vehicles
Sammanfattning : Making the transition to a ‘green’ vehicle fleet is a noteworthy endeavour for any policy maker. Under the current global pressures of increasing greenhouse gas emissions there is no doubt that all efforts that can be adopted in order to improve the sustainability of our cities should be explored.

12. An Approach to Business Modeling for Sustainable Personal Road Transport
Sammanfattning : Between 1950 and 2013 the total amount of Swedish travelling has increased from about 20 billion to about 140 billion passenger kilometers. This included an increase in travelling with private cars from about 3 billion to about 105 billion passenger kilometers, and in bus travelling from about 2.5 billion to about 5 billion passenger kilometers.

13. Life cycle assessment of transport systems and transport infrastructure : Investigating methodological approaches and quantifying impacts at project and network levels
Sammanfattning : Reducing greenhouse gas emissions from the transport sector is a key challenge to reach global climate targets and limit global warming to below 2 ºC. The use of life cycle assessment (LCA) may provide knowledge about the environmental impacts of transport systems so that emission reduction measures can be identified. LÄS MER
14. Impacts of Active Transport on Health : with a focus on physical activity, air pollution, and cardiovascular disease
Sammanfattning : Background: There are increasing number of health impact assessment studies investigating the health effects by transferring trips made by motorised transport to active commuting; however, air pollution exposure during active commuting and its impact on health has been less thoroughly assessed. It is furthermore uncertain whether there is any interaction effect between air pollution and physical activity for the risk of cardiovascular diseases. LÄS MER
15. Sociotechnical system studies of the reduction of greenhouse gas emissions from energy and transport systems
Sammanfattning : It is agreed that greenhouse gas (GHG) emissions from energy and transport systems must be reduced. Technical means exist to reduce GHG emissions from these sources. However, these emission-reduction measures are not implemented to a high enough degree. LÄS MER
