2. 1. Gas Exchange over Aquatic Interfaces and its Importance for Greenhouse Gas Emission

   Author : Jovana Kokic; Sebastian Sobek; Erik Sahlée; Marcus B. Wallin; Anne Ojala; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; gas exchange; lake; stream; lake sediment; headwaters; carbon dioxide; methane; greenhouse gas emission; carbon; turbulence; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

   Abstract : Aquatic ecosystems play a substantial role in global cycling of carbon (C), despite covering only about 4% of the earth surface. They emit large amounts of greenhouse gases (GHG) to the atmosphere, comparable to the amount of C stored annually in terrestrial ecosystems. In addition, C can be buried in lake sediments.

4. 2. Land use effects on greenhouse gas emissions from boreal inland waters

   Author : Marcus Klaus; Jan Karlsson; Peter Staehr; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; greenhouse gas; boreal forest; carbon cycling; whole-ecosystem experiment; limnology; metabolism; forest clearcutting; nitrogen enrichment;

   Abstract : Anthropogenic activities perturb the global carbon and nitrogen cycle with large implications for the earth’s climate. Land use activities deliver excess carbon and nitrogen to aquatic ecosystems. In the boreal biome, this is mainly due to forestry and atmospheric deposition. READ MORE

5. 3. Building renovation processes towards low greenhouse gas emissions and energy use

   Author : Stefan Olsson; Tove Malmqvist; Göran Finnveden; Dennis Johansson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renovation processes; buildings; energy efficiency; greenhouse gas emissions; target levels;

   Abstract : Buildings from the record year era are now 40 – 55 years old and in many cases in need of extensive renovation measures. This need for renovation could be seen as an opportunity to achieve overarching sustainability target levels and to perform renovation with a holistic approach. READ MORE

6. 4. Drivers of Climate Change? Political and Economic Explanations of Greenhouse Gas Emissions

   Author : Ole Martin Laegreid; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Greenhouse gas; Climate change; Environmental Kuznets curve; Political institutions;

   Abstract : This PhD dissertation examines if social scientific theories can explain historical trajectories of greenhouse gas emissions. The manuscript includes an introductory chapter and four articles that consider annual emissions in countries across the world, during the time-period 1960-2014. READ MORE

7. 5. Effects of forest management on greenhouse gas fluxes in a boreal forest

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

   Abstract : 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.
