1. Carbon Dioxide in Supermarket Refrigeration
University dissertation from Stockholm : KTHAbstract : This thesis theoretically and experimentally investigates different aspects of the application of CO2 in supermarket refrigeration. Theoretical analysis has been performed using computer simulation models developed to simulate CO2 indirect, NH3/CO2 cascade, CO2 trans-critical and direct expansion (DX) R404A systems. READ MORE

2. Lake Fluxes of Methane and Carbon Dioxide
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : Methane (CH4) and carbon dioxide (CO2) are two important greenhouse gases. Recent studies have shown that lakes, although they cover a small area of the globe, can be very important natural sources of atmospheric CH4 and CO2. READ MORE

3. Land-atmosphere exchange of carbon in a high-Arctic wet tundra ecosystem
University dissertation from Lunds universitets geografiska institutionAbstract : Popular Abstract in Swedish Under den senaste tiden har problematiken med klimatförändringarna debatterats livligt. För att kunna förutspå den framtida omfattningen av klimatförändringarna och vilka konsekvenser dessa kommer att ha är det ytterst relevant att känna till utbytet av växthusgaser mellan atmosfär och jordens alla ekosystem.

4. Green consumption energy use and carbon dioxide emission
University dissertation from Umeå : KulturgeografiAbstract : The aim of this thesis is to explore the quantitative potential to reduce energy requirements and CO2 emissions through changed patterns of consumption, given unchanged levels of consumption expenditure. The thesis question is analysed using a systems analysis approach which in this case means that life cycle assessment data on energy requirements and CO2 emissions related to household consumption are combined with a financial and behavioural analysis to make sure that the budget constraint is kept and that both the first and second order effects of adopting a green consumption pattern are analysed.

5. Production and emission of CO2 in two unproductive lakes in northern Sweden
University dissertation from Umeå : Institutionen för Ekologi, miljö och geovetenskap, Umeå universitetAbstract : Unproductive lakes are one of few natural landscape compartments with net release of carbon to the atmosphere. Lakes also generally decrease the net terrestrial carbon uptake, since most of the CO2 production in unproductive lakes are derived from organic carbon produced on land (e.g. in forests). READ MORE
