In recent years, the negative impacts of anthropogenic GHG (greenhouse gas) emissions on the global climate and the rising energy demand have underscored the urgent need to transition significantly from fossil fuel dependence to renewable energy sources. This transition is essential for achieving sustainability and mitigating climate change, in line with UE protocols imposed for climate neutrality under the Green Deal. Advanced technologies and innovative approaches are critical to this energy transition, and this workshop brings together contributions from academia and industry to synergize efforts in driving technological growth towards a sustainable future. While the energy transition is predominantly driven by technological advancements, its broader scope significantly impacts architecture, urban planning and redevelopment, environmental and social sustainability. The workshop "Pathways to Sustainability: Strategies for Effective Transitions" aims to foster interdisciplinary collaboration, share cutting-edge research, and promote innovation in sustainable energy technologies, enhancing our collective understanding and drive towards a sustainable energy future. The workshop will explore novel strategies for energy harvesting such as advances in photovoltaics, harnessing ambient vibrations and thermal gradients. The integration of nanotechnology and flexible electronics opens new frontiers in sustainable power generation, offering promising solutions for various applications, from IoT devices to remote sensors. Hydrogen’s role as an energy carrier for energy storage and utilization will also be discussed, along with challenges in production, storage, and distribution. The integration of hydrogen technologies, such as electrolyzers and fuel cells, into the energy market is set to transform energy generation and consumption, making significant steps towards decarbonization. Sustainable bio-based processes and technologies for converting agricultural and industrial residues into biofuels and high-value products will be emphasized, supporting the circular economy and offering renewable energy solutions. Short-term strategies such as the capture and abatement of pollutants like CO₂ are also essential. The rational design and synthesis of advanced nanostructured materials facilitate efficient separation processes, including CO₂ capture and resource recovery. Furthermore, the electrochemical reduction of CO₂ into value-added products, driven by renewable sources, offers a compelling avenue for CO₂ valorization. Developing high-performance electrocatalysts that balance selectivity, stability, efficiency, and cost-effectiveness is key to transforming CO₂ into valuable resources, thereby addressing short-to-medium-term emission challenges while promoting long-term sustainability. Decarbonization of urban environments through deep building renovation, urban space regeneration, and the establishment of renewable energy communities will be discussed as essential steps for achieving sustainable cities, in line with EU decarbonization targets. The integration of renewable energy technologies into urban planning and architecture will also be examined. Finally, comprehensive methodologies for evaluating environmental and social impacts are vital for developing sustainable energy systems. Life Cycle Assessment (LCA) and Social Life Cycle Assessment (S-LCA) frameworks provide robust approaches for assessing the sustainability of energy technologies.

Co-organized with Polytechnic University of Turin & University of Milan Chair: Wenbin CAO, USTB, China
The global shift towards sustainable energy systems necessitates comprehensive methodologies for evaluating environmental impacts and ensuring safe and sustainable development. This symposium integrates Life Cycle Assessment (LCA) and the Safe and Sustainable by Design (SSbD) framework within the context of the energy transition. LCA offers a robust approach to quantifying the effects on environments associated with energy technologies across their entire lifecycle—from resource extraction through to disposal. In addition to environmental consideration, a comprehensive evaluation of the impact of novel technologies must also consider the social dimension. Social Life Cycle Assessment (S-LCA) methodologies are promising tools for the evaluation of the social impact of technologies, products and services, through qualitative and semi-quantitative approaches. The afore-mentioned life cycle assessment methodologies are crucial for the design, development and production of clean, sustainable and safe chemical and materials. The SSbD framework emphasizes the proactive design of energy systems and technologies to minimize environmental harm, enhance safety, and ensure compliance with sustainability goals. This symposium focuses on state-of-the-art strategies for the assessment of environmental and social impacts, highlighting benefits and limitations of the current approaches through the presentation of case studies. Key findings underscore the importance of interdisciplinary collaboration and continuous innovation for the development of reliable assessment methodologies, which will serve as guidelines for the design of safe and sustainable innovative material sand technologies.
