2. 1. Modelling Climate Policy – Trade-Off Metrics, Resource Markets, and Uncertainty

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

   Abstract : 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). READ MORE

4. 2. MAKING TRADE-OFFS IN THE GREENHOUSE: Relative Price Changes, Non-CO2 Greenhouse Gases and Tropical Deforestation in Climate Policy

   Author : Martin Persson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; GWP; discounting; RED; climate change; substitutability; Kyoto protocol; tropical deforestation; palm oil; biofuels; Amazon; climate policy; uncertainty;

   Abstract : This thesis, consisting of five separate papers, is an inquiry into climate policy and the trade-offs that have to be made when formulating such policy. It covers three major topics: (1) the economics of choosing a climate policy target; (2) the economic merits of the Global Warming Potentials (GWPs), the metric governing the trade-off between abatement of different greenhouse gases (GHGs) in the current climate regime; and (3) the promises and challenges with including the GHG emissions from tropical deforestation in a future climate regime.

5. 3. Flow boiling heat transfer, pressure drop and dryout characteristics of low GWP refrigerants in a vertical mini-channel

   Author : Zahid Anwar; Björn Palm; Rahmatollah Khodabandeh; Maria Fernandino; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mini micro-channels; R1234yf; R152a; R600a; R134a; Boiling heat transfer; Pressure drop; Dryout; Correlation;

   Abstract : Two-phase heat transfer in mini/micro-channels is capable of meeting the high cooling demands of modern high heat flux applications. The phase change process ensures better temperature uniformity and control for local hot spots. Furthermore, these compact channels could be helpful in reducing the required charge and material inventories. READ MORE

6. 4. Decision support for the implementation of low-carbon measures in the building sector

   Author : Nicolas Francart; Tove Malmqvist; Paula Femenias; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building; sustainability; environmental performance assessment; life cycle assessment; decision making; byggnad; hållbarhet; miljöprestandabedömning; livscykelanalys; beslutsstöd; Strategier för hållbar utveckling; Strategies for sustainable development;

   Abstract : The building sector is responsible for about a fifth to a third of global greenhouse gas (GHG) emissions. Therefore, a successful mitigation of GHG emissions over the entire life cycle of buildings is particularly important to achieve climate targets such as the Paris Agreement. READ MORE

7. 5. Computational framework for studying charge transport in high-voltage gas-insulated systems

   Author : Shailendra Singh; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; barrier discharge; low temperature plasma; drift diffusion equation; gaseous dielectrics; gas discharge; streamer propagation; high voltage;

   Abstract : Electrical switchgear industry dealing with transmission and distribution of power is strongly affected by the changing dynamics of climate control. Their main contribution to the global warming is through SF6 gas, having a GWP of 23500 (times of CO2). SF6 plays an important role in providing electrical insulation for these high voltage systems.
