21. Car movement patterns and the PHEV
Sammanfattning : Roughly 30% of Sweden’s total greenhouse gas emissions originate from transport and a majority of them from cars. The plug-in hybrid electric vehicle (PHEV) avoids the range limitation of the fully electric vehicle while still allowing for a major share of the fuel to be replaced by electricity from the grid and can thereby reduce greenhouse gas emissions, local pollutants and energy security concerns.

22. Land-Use and Climate Effects of Bioenergy: Carbon balances of Swedish forest bioenergy systems – and – Geospatial biomass supply-and-demand matching for Europe
Sammanfattning : In order to keep global warming below 2 degrees Celsius, greenhouse gas emissions have to be drastically reduced. Bioenergy can play a role in climate change mitigation by substituting for energy from fossil fuels; however, biomass is a limited resource associated with emissions from land use and land-use change.

23. On the contribution of forest bioenergy to climate change mitigation
Sammanfattning : Greenhouse gas (GHG) emissions have to be drastically reduced to keep global warming below 2 degrees. Bioenergy can play a role in climate change mitigation by substituting for fossil fuels. LÄS MER
24. On Sustainability of Biomass for Energy and the Governance Thereof
Sammanfattning : Due to concerns about climate change, energy security, and resource scarcity, non- renewable resources are increasingly being displaced by biomass. As with most human activities, the production of biobased products can be associated with negative impacts. Primarily, this relates to the biomass supply systems, i.e. LÄS MER
25. Towards Sustainable Bioenergy - Governance, Resource potentials and Trade-offs
Sammanfattning : The global energy system needs to be transformed from fossil dependent to renewable, to cope with the challenges of resource scarcity and climate change. Bioenergy can play an important role in this transformation, but land is scarce, and uncontrolled bioenergy expansion could have unacceptable consequences. LÄS MER
