2. 1. Land-Use and Climate Effects of Bioenergy: Carbon balances of Swedish forest bioenergy systems – and – Geospatial biomass supply-and-demand matching for Europe

   Author : Olivia Cintas Sanchez; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GIS; EU; bioenergy; Sweden; agriculture; residues; Forestry; climate change; GHG balances;

   Abstract : 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.

4. 2. Biorefinery systems for energy and feed production : greenhouse gas performance and energy balances

   Author : Hanna Karlsson Potter; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : 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. READ MORE

5. 3. Greenhouse gas emissions from rewetted extracted peatlands in Sweden

   Author : Sabine Jordan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : 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. READ MORE

6. 4. Assessing the sustainability of bioethanol production in Nepal

   Author : Dilip Khatiwada; Semida Silveira; Andrew Martin; Björn Karlsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Bioethanol; sustainability; life cycle assessment; net energy values; greenhouse gas GHG balances; sustainable development; least developed countries LDCs ; Nepal; Mechanical and thermal engineering; Mekanisk och termisk energiteknik; Climatology; Klimatologi;

   Abstract : 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. READ MORE

7. 5. On the contribution of forest bioenergy to climate change mitigation

   Author : Olivia Cintas Sanchez; Chalmers tekniska högskola; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Forest bioenergy; forest management; climate change; energy systems.; GHG balances; forest supply; carbon budget;

   Abstract : 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. READ MORE
