1. 1. Natural resources and sustainable energy : Growth rates and resource flows for low-carbon systems

   Författare :Simon Davidsson; Mikael Höök; Gert Jan Kramer; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; low-carbon technology; renewable energy; energy transitions; critical materials; energy metals; material flows; net energy; EROI; life cycle assessment; LCA; growth curves; curve fitting; resource depletion; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

   Sammanfattning : Large-scale deployment of low-carbon energy technologies is important for counteracting anthropogenic climate change and achieving universal energy access. This thesis explores potential growth rates of technologies necessary to reach a more sustainable global energy system, the material and energy flows required to commission these technologies, and potential future availability of the required resources.

3. 2. Low-Carbon City Initiatives in China : Planning Approaches, Dilemmas and Opportunities

   Författare :Guanghong Zhou; Björn Frostell; Karel Mulder; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-carbon city; Urban planning; Metabolic approach; Industrial Ecology; Industriell ekologi;

   Sammanfattning : In order to reduce greenhouse gas (GHG) emissions, tackle climate change and move toward sustainable development, the central government in China has proposed low-carbon city development as the national strategy and relevant initiatives have been taken by local governments. This thesis analyses current low-carbon city programmes and planning approaches in China, identifies limitations and proposes a metabolic approach that could be used to account for physical resources, monitor GHG emissions and involve stakeholders in the planning process.

4. 3. On the Incentives to Shift to Low-Carbon Freight Transport

   Författare :Fredrik Eng Larsson; Teknisk logistik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-carbon transport; green logistics; sustainability; operations and the environment; supply chain management; incentive alignment;

   Sammanfattning : The transport sector accounts for approximately 20% of EU-27 greenhouse gas (GHG) emissions, and 27% of U.S. GHG emissions. With the Kyoto Protocol, Sweden and several other nations have agreed to reduce these emissions. LÄS MER

5. 4. Trade-offs and conflicting objectives of decision-making investments in low-carbon technology portfolios for sustainable development : National and continental insights offered by applying energy system models

   Sammanfattning : Energy infrastructure and appropriate energy policies are crucial for sustainable development and to meet Sustainable Development Goals (SDGs). Limiting global warming potential below 1.5oC would require “rapid and far-reaching” transitions and unprecedented changes in all aspects of society. LÄS MER

7. 5. 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
