- Strategies for promoting climate-smart cities and fostering an eco-friendly culture in urban environments: a case study of Porto, Portugal; Curitiba, Brazil; and SingaporePublication . Esho, Esther Oreofeoluwa; Dinis, Maria Alzira PimentaUrbanization has become a defining characteristic of modern civilization, with over half of the global population now residing in cities. While urban growth drives economic development and innovation, it also imposes significant environmental costs, including heightened carbon emissions, resource depletion, and widespread air and water pollution. Addressing these pressing challenges necessitates the creation of resilient and sustainable urban environments, leading to the emergence of climate-smart cities. These cities integrate climate adaptation and mitigation strategies into urban planning, infrastructure development, and community engagement to reduce greenhouse gas emissions, enhance resilience to climate impacts, and foster eco-friendly lifestyles. This study examines the concept of climate-smart urban development and its critical role in combating climate change, promoting environmental sustainability, and strengthening the resilience of urban areas in the face of global challenges. Climate-smart cities are essential for addressing global climate change challenges and achieving sustainable urban development. Porto, Curitiba, and Singapore indicate innovative approaches to sustainable transportation, green building practices, and climate-resilient infrastructure through their respective case studies. These cities serve as global models for urban sustainability, demonstrating how integrated planning, innovative technologies, and community engagement can promote resilience, mitigate climate change impacts, and enhance quality of life for urban residents. To promote climate-smart cities, policymakers should prioritize investments in resilient infrastructure, renewable energy deployment, and sustainable transportation systems. Additionally, raising public awareness and fostering community engagement are crucial for building support for climate-smart initiatives and fostering an eco-friendly culture in urban environments.
- Sustainable generative AI and quantum computing: review assessment on the environmental impact of generative AI and quantum technologiesPublication . Esho, Esther Oreofeoluwa; Akinyelu, Andronicus Ayobami; Dinis, Maria Alzira PimentaThe rapid advancement of Generative Artificial Intelligence (GenAI) and Quantum Computing (QC) presents transformative opportunities, yet their high computational requirements raise concerns about their environmental sustainability. This comprehensive review examines the ecological footprint of both technologies, focusing on key metrics like energy consumption, carbon emissions, and resource depletion. Findings from existing studies consistently indicate that the impact of GenAI is mostly driven by the immense energy demands of large-scale model training and inference. Moreover, findings from the review reveal that the footprint of QC largely stems from the energy-intensive cryogenic cooling and rare material requirements of its specialized hardware. This paper benchmarks current approaches to environmental assessment, highlighting the important role of Life Cycle Assessment (LCA) in providing a holistic view of the classification of environmental impacts across the entire supply chain, from manufacturing to disposal. This study proposes a range of domain-specific mitigation strategies, including algorithmic optimizations like pruning and distillation for AI, and cryogenic and material sourcing improvements for quantum systems. This study also proposes a framework for proactive, responsible innovation and identifies some gaps in the literature, such as the lack of standardized metrics and transparent reporting. There is a need to embed eco-conscious principles in the design of future technologies and highlight opportunities where these technologies can be used to handle broader climate challenges. The findings in this study can be used by policymakers, researchers, and industry stakeholders in aligning technological progress with global climate and sustainability goals.
