1. 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. LÄS MER
2. Biorefinery systems for energy and feed production : greenhouse gas performance and energy balances
Sammanfattning : The current dependence on fossil fuels is problematic because these are a finite resource and because their combustion causes environmental degradation. Biorefineries produce a variety of valuable products from biomass that can replace products from petroleum refineries. LÄS MER
3. Greenhouse gas emissions from rewetted extracted peatlands in Sweden
Sammanfattning : Peat extraction for horticultural purposes and energy production has a long tradition in Northern Europe. Related drainage activities directly affect the greenhouse gas (GHG) balance due to oxidative peat decomposition and denitrification, with concomitant emissions of carbon dioxide (CO₂) and nitrous oxide (N₂O). Rewetting, i.e. LÄS MER
4. Assessing the sustainability of bioethanol production in Nepal
Sammanfattning : Access to modern energy services derived from renewable sources is a prerequisite, not only for economic growth, rural development and sustainable development, but also for energy security and climate change mitigation. The least developed countries (LDCs) primarily use traditional biomass and have little access to commercial energy sources. LÄS MER
5. 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
