1. 1. Greenhouse gas emissions from peat soil thawing in spring : a comparison between fertilized and unfertilized soil

   University essay from SLU/Dept. of Soil and Environment

   Author : Fanny Otterlin Karlsson; [2024]
   Keywords : agricultural soil; carbon dioxide; freeze-thaw cycles; nitrous oxide; soil temperature; water content;

   Abstract : Peat soils drained for agriculture and forestry contribute to a significant amount of greenhouse gas emissions. Nitrous oxide is a greenhouse gas with high warming potential and agriculture in general accounts for about 70 % of nitrous oxide emissions. READ MORE

3. 2. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Linnéa Eriksson; [2023-04-20]
   Keywords : soil C:N; forest production; 15N isotope dilution; gross N mineralisation; ammonium; soil carbon; soil nitrogen; root exudates; stoichiometric decomposition; boreal forests; priming; microbial C limitation;

   Abstract : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. READ MORE

4. 3. Analysing the effects of 24/7 Carbon-free Energy procurement strategies on the electricity system : Case Study of commercial and industrial sector in the Netherlands

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : NINA JABŁOŃSKA; [2023]
   Keywords : 24 7 Carbon-free Energy; carbon accounting; corporate electricity procurement; Energy Attribute Certificates; hourly matching; the Netherlands.; 24 7 kolfri energi; koldioxidredovisning; företagens elupphandling; energiattributcertifikat; timmatchning; Nederländerna.;

   Abstract : Considering the growing importance of the electricity sector in the worldwide decarbonisation efforts, as well as large volumes of energy consumed by the commercial and industrial (C&I) sector, corporate power procurement is found to be a significant contributor to building a net zero economy. Within this topic, hourly matching of carbon-free electricity supply with demand, or 24/7 Carbon-free Energy (24/7 CFE), is identified as a next-generation power procurement framework, with growing interest from a wide range of stakeholders in the energy sector and benefits backed by robust research evidence.

5. 4. Sustainability demands on internal and external providers of IT

   University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

   Author : Emma Lenman; Ida Appelgren; [2023]
   Keywords : sustainable IT; sustainability; IT; green IT; data governance; energy efficient; greenhouse gas emissions;

   Abstract : The use of IT in companies is constantly expanding, and therefore, so is the energy consumption and carbon footprint from IT. If companies do not take steps towards more sustainable IT usage, the footprint will continue to expand, toxic metals will be used in hardware and the usage of world resources will not become more circular.

6. 5. Methanobacterium cauma sp. nov., a hydrogenotrophic, halotolerant methanogen from an active serpintinization system at Chimaera seep

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Aubree Stephens; [2023]
   Keywords : methanogen; archaea; hydrogenotroph; halotolerant; Methanobacterium; Chimaera seep; methanogenesis;

   Abstract : The archaeal branch of life represents some of the oldest life forms on Earth. Archaea are believed to have diverged from Prokaryotes roughly 3.5 billion years ago and it’s theorized that biological methane production started around this time as well. This would make methanogenesis one of the oldest metabolisms on our planet. READ MORE
