The construction industry is responsible for a significant amount of raw material consumption and environmental footprints. Therefore, sustainable construction became a hot topic, which strives to reduce material consumption, limit constructional waste disposal, and decrease contribution to climate change. In line with Qatar's commitment to organizing a sustainable FIFA World Cup in 2022, this study aims to conduct an environmental life cycle assessment (LCA) for the construction of the Education City Stadium. The work presented here provides the first empirical LCA for analyzing the environmental and economic impacts of circular economy application in a World Cup stadium. In this research, the cyclopean concrete (CYC) methodology was utilized, which incorporate the site excavated boulders with the concrete mix to cast the under-raft foundation of the stadium. This approach was compared to the conventional concrete (CC) casting approach to assess the extent to which the newly developed methodology can reduce the environmental and economic burdens. The obtained results have shown a 32% reduction in greenhouse gas emissions when adapting the CYC approach. Thus, the CYC holds a strong promise to achieve the required structural behavior with a low-cost alternative material from existing waste products in Qatar and a lower environmental impact than the CC.

建筑行业负责大量的原材料消耗和环境足迹。因此，可持续建筑成为一个热门话题，它致力于减少材料消耗，限制建筑垃圾的处理以及减少对气候变化的影响。根据卡塔尔对2022年举办可持续FIFA世界杯的承诺，本研究旨在为教育城体育馆的建设进行环境生命周期评估（LCA）。本文介绍的工作提供了第一个经验LCA，用于分析世界杯体育场馆中循环经济应用对环境和经济的影响。在这项研究中，采用了独眼巨人混凝土（CYC）方法，将现场挖出的巨石与混凝土混合在一起，以浇筑体育场的筏下基础。将该方法与常规混凝土（CC）浇铸方法进行了比较，以评估新开发的方法可以减轻环境和经济负担的程度。采用CYC方法时，获得的结果表明温室气体排放量减少了32％。因此，CYC拥有使用卡塔尔现有废物中的低成本替代材料并实现比CC更低的环境影响来实现所需结构性能的强烈希望。采用CYC方法时，获得的结果表明温室气体排放量减少了32％。因此，CYC拥有使用卡塔尔现有废物中的低成本替代材料并实现比CC更低的环境影响来实现所需结构性能的强烈希望。采用CYC方法时，获得的结果表明温室气体排放量减少了32％。因此，CYC拥有使用卡塔尔现有废物中的低成本替代材料并实现比CC更低的环境影响来实现所需结构性能的强烈希望。
