1. 1. Energy Embodied in Trade, 1970–2014

   Författare :Viktoras Kulionis; Ekonomisk-historiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economic Growth; Energy use; Trade; Footprint; Carbon Emissions; Input-Output Analysis; Structural Decomposition Analysis;

   Sammanfattning : Ongoing globalisation combined with the rapid pace of technological change have generated significant growth in economic activities and have improved the welfare and living standards of many people around the world. e opening up of the world economy has also led to unprecedented surges in international trade and has fundamentally transformed the way that goods and services are produced, exchanged and consumed.

3. 2. The origin and fate of sediment organic carbon in tropical reservoirs

   Författare :Anastasija Isidorova; Sebastian Sobek; Rafael Marcé; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; methane; carbon burial; tropical reservoirs; sediment; carbon cycle; limnology; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

   Sammanfattning : Recently, the construction of reservoirs has boomed, particularly in the tropics, but the impact of reservoirs on the global carbon cycle is not evident. Reservoirs accumulate sediments that simultaneously bury organic carbon (OC) and thus act as a C sink, and also produce methane (CH4) and thus emit a strong greenhouse gas. LÄS MER

4. 3. Potential of Organosolv Lignin Nanoparticles as a Sustainable Flotation Reagent : Towards a Low-Carbon Footprint Mining Industry

   Författare :Katerina Hruzova; Ulrika Rova; Saija Luukkanen; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organosolv lignin particles; Nanoparticles; Flotation reagent; Copper recovery; Biokemisk processteknik; Biochemical Process Engineering;

   Sammanfattning : The green transition is driving a steep increase in the demand for minerals, which has put the focus on more responsible and sustainable mining practices as there is a growing pressure on mining operations to minimise their environmental footprint, mitigate risks in neighbouring communities, and decrease the consumption of natural resources. In 2022, mineral froth flotation was used to recover 18 million tonnes of copper from copper ore, accounting for 80% of total copper mine output. LÄS MER

5. 4. Industrial Ecology and Development of Production Systems : Analysis of the CO2  Footprint of Cement

   Författare :Roozbeh Feiz; Mats Eklund; Jonas Ammenberg; Henrikke Baumann; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrial ecology; industrial symbiosis; industrial development; life cycle assessment; multi-criteria assessment; CO2 footprint; cement;

   Sammanfattning : This research is an attempt to create a comprehensive assessment framework for identifying and assessing potential improvement options of cement production systems.From an environmental systems analysis perspective, this study provides both an empirical account and a methodological approach for quantifying the CO2 footprint of a cement production system.

7. 5. Felling Forests from Afar: Quantifying Deforestation Driven by Agricultural Expansion and International Trade

   Författare :Florence Pendrill; Chalmers tekniska högskola; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Forest transitions; Land cover; Carbon footprints; Agriculture; Forestry; Carbon emissions; Land use; International trade; Deforestation;

   Sammanfattning : Deforestation is a major source of human-caused greenhouse gas emissions and the largest threat to terrestrial biodiversity. Most forest loss is due to the expansion of agricultural land use increasingly driven by international demand for food, fuel and fibre. LÄS MER
