6. Biomass in a Sustainable Energy System
Sammanfattning : The increased use of biomass for energy is as a key strategy in reducing carbon dioxide (CO2) emission, which represents the largest anthropogenic contribution to the greenhouse effect. In this thesis, aspects of an increase in the utilisation of biomass in the Swedish energy system are treated. LÄS MER
7. Growth versus the Environment - Is There a Trade-off?
Sammanfattning : This book shows that the intensity of use of energy and materials in OECD countries is diminishing over time despite falling metal and energy prices. Material demand is sometimes falling in absolute terms, but there are also a few examples of rapid growth. LÄS MER
8. Control of Hybrid Electric Vehicles with Diesel Engines
Sammanfattning : This thesis is an approach to improve electric hybrid vehicles with respect to fuel consumption and to fulfil the future intended NOX emission regulations. It is based upon the conclusions made in the licentiate thesis Analysing Hybrid Drive System Topologies (Jonasson, 2002). LÄS MER
9. Tourism, Ecosystem Functions, and Human-Environmental Relations
Sammanfattning : The thesis aims at deconstructing the sustainable tourism paradigm: can tourism be "a global strategy for sustainable development", as the tourist industry claims? And will developing countries in particular profit from tourism development?To most international organizations and institutions (from the World Wide Fund for Nature to The World Bank), tourism, if carefully managed, is a positive, sustainable development tool. However, the research presented in this thesis exposes this view as unrealistically optimistic for at least three reasons: first of all, global environmental change caused by tourism has never been investigated and integrated with the discourse on sustainable tourism development.

10. On the Determination of Reactive Compounds in Aerosols
Sammanfattning : Many sources of airborne contaminants have always been present in various work environments. With the development of thermosetting plastic systems, the use of reactive chemical compounds was greatly increased and thus also the risk of exposure to reactive and potentially hazardous compounds.
