Later City News: Qatar is committed to developing the football World Cup event with reduced CO2-eq emissions and therefore the SCDL aims to design, construct, and sustainably operate its stadiums.

Research recently published by "Environmental Impact Assessment Review" shows that In line with Qatar's commitment to organizing a sustainable FIFA World Cup in 2022, this country successfully reduced 32% in greenhouse gas emissions when adapting the cyclopean concrete (CYC) approach.

The most interesting finding was that the activity of transporting the excavated boulders for disposal into landfills contributed to the total consumed fuel in the CC case by 6%, while it has no contribution in the CYC case since such activity was avoided. This has prevented additional transport distance of tripper trucks, which comprises 296 trips to the dumping site that is 50 km away from the construction site, and as a result, 10,881.95 l and 29,381.27 kg of fuel consumption and CO2-eq emissions were saved, respectively.

This research has published by AbatharAl-Hamrani, DoyoonKim, MuratKucukvar, Nuri Cihat Onat researchers from Qatar University and Qatar Foundation.

Based on the LCA results, the highest CO2-eq emissions were due to concrete ingredients production, which accounts for 94% of the total emissions for both approaches the CYC and the CC, wherein 53% of them were due to cement production and 41.6% were for the rest of the ingredients. This was followed by approximately 5% of emissions that emerged from the transportation process and only 1% of emissions emerged from excavating, pouring, and cleaning processes.

This research presented the first empirical LCA method for understanding the environmental impacts of a circular economy application in the FIFA World Cup Stadium construction in Qatar. The proposed method can provide vital insights for decision-makers towards achieving an environmentally friendly event using circularity principles in design and construction. For future work, the researchers also propose to conduct a detailed LCA on the 2022 FIFA World Cup Ras Abu Aboud Stadium, which is a container stadium and will be entirely dismantled and reused after 2022. Conducting such a study on this unprecedented stadium in the history of World Cups would reveal the potential benefits of CE from a modular construction perspective.
