   Abstract : Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. READ MORE

4. 2. Neighborhood Design and Travel : a Study of Residential Quality, Child Leisure Activity and Trips to School

   Author : Pia Westford; Dick Urban Vestbro; Anders Hagson; KTH; []
   Keywords : urban design; neighborhood; car use; child leisure activity; school trips; lifestyle; perceived environment;

   Abstract : Sustainable urban mobility calls for well-informed design of neighborhoods. Although many studies have been conducted in the field, there is little evidence about the relationships between design elements, urban quality and behavior. Little is also known about residents’ valuation of design and urban quality in this context. READ MORE

5. 3. Integrating Packaging and Logistics in Industrial Development

   Author : Urban Bjöörn; Förpackningslogistik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Global Enterprises today are dependent on performance within complex networks. To become effective and efficient, it is more important than ever to organize operations in order to capitalize on resources and to integrate different activities. This means that the supply chain and logistics have become core activities in international enterprises. READ MORE

   Abstract : Transportation is embedded in the fabric of society and a key enabler of socio-economic development, but it is also a major source of carbon dioxide (CO2) and local air pollution (AP). Cities collectively account for around three quarters of total energy-related CO2 emissions, and the negative health impacts from local APs are most felt in dense urban environments. READ MORE
