    Adopting net zero neighborhoods (NZN) combined with circular economy are increasingly recognized as an essential strategy for construction companies, allowing their transition towards sustainability and contributing to climate change mitigation. Transforming existing neighborhoods into NZN is necessary to achieve energy self-sufficiency and net zero by 2050. The success of NZN hinges on government initiatives. However, existing studies appear to lack a comprehensive exploration of the transformation initiatives within NZN, spanning aspects like raw materials, construction practices, transportation, and waste management, particularly in terms of technological advancements. To address the gap, this research introduces a conceptual framework that integrates the multiple case studies design method with an urban transformative capacity model. This innovative framework is the first application of a multi-level urban transformative capacity model in transforming existing neighborhoods into NZN within a specific region. This research specifically utilizes South Wales in the UK as a case study. It identified four key initiatives in technology, construction, transportation, and waste management. These initiatives offer significant benefits, including fostering a more sustainable and environmentally friendly construction industry through enhanced traceability and efficiency, and simultaneously promoting social sustainability by improving community engagement, providing social benefits through sharing economy initiatives, and creating new green job opportunities.

    Integrating blockchain with digital product passports for managing reverse supply chain
    (Elsevier, 2025) Xia, Hanbing; Li, Jiahong; Li, Qian Jan; Milisavljevic-Syed, Jelena; Salonitis, Konstantinos
    The reverse supply chain (RSC), vital for circular economies, faces considerable challenges, including transparency deficits, trust issues, and inefficient information sharing. Blockchain can enhance transparency and traceability in circular economy practices, but it has limitations in providing detailed, product-specific lifecycle data. In contrast, the digital product passport (DPP) is designed to provide this detailed information, offering comprehensive, high-quality data across a product’s entire lifecycle. By integrating DPP, the inherent data limitations of blockchain can be overcame, making it a more useful tool in promoting sustainable practices. The aim of this research is to explore integrating blockchain technology and the DPP to manage RSC for circular economy practices. To achieve this, a novel conceptual framework is presented that merge blockchain with DPP, potentially enhancing information efficiency throughout the entire lifecycle of end-of-life products and reducing uncertainties in RSC processes.
