1. 1. Forests and Greenhouse gases. Fluxes of CO2, CH4 and N2O from drained forests on organic soils

   Författare :Karin von Arnold; Leif Klemedtsson; Mats Nilsson; Björn Hånell; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Greenhouse gases; GHG; fluxes of CO2; CH4; drained forests; organic soils; Skogsbotanik; miljöaspekter; växthusgaser; Water in nature and society; Vatten i natur och samhälle;

   Sammanfattning : One of the largest environmental threats believed to be facing us today is global warming due to the accumulation of green house gases (GHG). The concentrations of GHG in the atmosphere are a result of the net strength of different sinks and sources. LÄS MER

3. 2. Effects of forest management on greenhouse gas fluxes in a boreal forest

   Författare :Patrik Vestin; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :Forest management; Greenhouse gas fluxes; Clear-cutting; Thinning; Stump harvesting; Selective cutting; Eddy-covariance; Flux-gradient; Greenhouse gas budgets; CO2; CH4; N2O;

   Sammanfattning : Forest ecosystems cover 31% of the terrestrial land area and store large amounts of carbon in biomass and in soils. The 2015 Paris Agreement recognizes the importance of sinks and reservoirs of greenhouse gases (GHGs) in forests and the importance of enhancing them through sustainable forest management policies.

4. 3. Clean development Mechanism (CDM) Policy and Implementation in China

   Författare :Lei Zeng; Leif Gustavsson; Mälardalens högskola; []
   Nyckelord :Climate change; Clean development mechanism; CDM; CO2; Green House Gas; GHG; landfill gas; sustainable development; China; Energi- och miljöteknik;

   Sammanfattning : China is the second largest emitter of greenhouse gases (GHG) in the world. Since 68% of its primary energy is from coal, China’s average energy intensity is 7.5 times higher than the EU and 4.3 times higher than the US (EU, 2003). LÄS MER

5. 4. Modelling Climate Policy – Trade-Off Metrics, Resource Markets, and Uncertainty

   Författare :Daniel Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; OPEC; GWP; energy; uncertainty; biomass; climate change; oil; land use; greenhouse gases; Kyoto Protocol;

   Sammanfattning : This thesis consists of five papers related to climate change policy. In paper I andpaper II we discuss the use of Global Warming Potentials (GWPs) that facilitate the tradeoffbetween abatement of the different greenhouse gases (GHGs). LÄS MER

7. 5. Regional Energy Systems with Retrofitted Combined Heat and Power (CHP) Plants

   Författare :Song Han; Yan Jinyue; Thorin Eva; Deng Shiming; Mälardalens högskola; []
   Nyckelord :Combined heat and power; Waste-to-Energy WtE ; Regional energy system; Greenhouse gases GHG ; Retrofitting; Optimization; Kraftvärme; Avfall-till-Energi; Regionala Energisystem; Växthusgaser; Uppgradering; Optimering.; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Fossil fuel depletion, economic development, urban expansion and climate change present tough challenges to municipal- and regional-scale energy systems. Regional energy system planning, including waste treatment, renewable energy supply, energy efficiency, and climate change, are considered essential to meet these challenges and move toward a sustainable society.
