The embodied carbon associated with buildings, which covers the carbon emissions created by the extraction, transportation, construction, maintenance, replacement, demolition, and disposal of building materials, contributes 11% of global carbon emissions
and approximately 75% of a building\u2019s total emissions over a typical 60-year lifetime. <\/a>Its impact is fixed at the time of construction and cannot be reduced once the building is constructed.<\/div>\nEmbodied carbon constitutes a major source of Scope 3 emissions \u2013 i.e., indirect emissions that occur along a company\u2019s value chain \u2013 for real estate companies. In 2022, Hang Lung\u2019s scope 3 emissions were about 72% of its overall emissions, with embodied carbon emissions from building materials its largest source of emissions. Hang Lung is squarely confronting embodied carbon reduction and the importance of having strategic collaboration partners to work together.<\/p>\n
Mr. Adriel Chan, Hang Lung Properties Vice Chair, and Chair of its Sustainability Steering Committee, said: \u201cDecarbonizing real estate, particularly from embodied carbon, is a marathon, not a sprint. We believe the partnership with CLEANCO2 and Zhejiang University will enable exciting innovations to move forward on this journey. At the same time, we will continue to work closely with our suppliers to reduce emissions through innovative and pragmatic solutions. We encourage other real estate companies to join in accelerating and scaling such innovations.\u201d<\/p>\n
\u201cConcrete is the most used building material in the world, and we cannot ignore the impact of its carbon emissions. The strategic cooperation between Hang Lung Properties and CLEANCO2 is not only a solid step towards CLEANCO2\u2019s \u2018100 million tons vision\u2019 \u2013 which is using CCUS technology to fix and sequester 100 million tons of CO2<\/sub>, but also a forward-looking exploration and attempt by both sides to reduce the embodied carbon for future buildings.\u201d said Mr. Zhao Chao, CEO of CLEANCO2.<\/p>\nThe collaboration will leverage CLEANCO2\u2019s proprietary carbon dioxide mineralization technology to advance CCUS applications through two initiatives at Westlake 66, Hangzhou:<\/p>\n
1) Low Carbon RCA<\/p>\n
First, we are reusing waste concrete from our Westlake 66 development project in Hangzhou. The waste concrete will be crushed into aggregate and produced into low carbon RCA through a carbon dioxide mineralization process. A life cycle assessment has found that the low carbon RCA has significant potential to reduce emissions compared to normal aggregate when used as raw material for concrete. The Company and CLEANCO2 have completed a small scale pilot project with the low carbon RCA and are now evaluating this process at a medium scale, with 150 tons of waste concrete.<\/p>\n
2) Low Carbon Concrete Bricks<\/p>\n
Second, we will use CLEANCO2 low carbon concrete bricks on the secondary partition walls of the basement of our Westlake 66 project (the total number of bricks used can cover a wall area of around 17,000m2<\/sup>) \u2013 the first commercial development project in mainland China and Hong Kong to do so. These bricks will use cement, fly ash and other solid waste together with CLEANCO2\u2019s carbon dioxide mineralization process. The embodied carbon emissions of the low carbon concrete bricks are expected to be 87.5% lower than conventional shale bricks.<\/p>\nThe technology developed by CLEANCO2 originated from the State Key Laboratory of Clean Energy Utilization (CEU) of Zhejiang University. In 2020, as a supported R&D project under the 13th<\/sup> Five-Year Plan, the \u201cKey Technologies of CO2<\/sub> Deep Mineralization Curing Building Materials and 10,000-ton Industrial Demonstration\u201d was completed by Zhejiang University. Since 2020, CLEANCO2 has officially cooperated with CEU. They have jointly undertaken several national and local research and development projects related to CCUS technology and jointly built the \u201cZhejiang University – CLEANCO2 United Laboratory of CO2<\/sub> Mineralization Utilization Technology\u201d, the first CO2<\/sub> mineralization utilization experimental base in China with potential to achieve large-scale industrial production globally.<\/p>\nWestlake 66, Hangzhou is Hang Lung\u2019s 11th<\/sup> large-scale development on the Mainland, comprising of a world-class shopping mall, five Grade A office towers, and the prestigious hotel Mandarin Oriental Hangzhou. It is scheduled for completion in phases from 2024 onwards.<\/p>\nHashtag: <\/b>#HangLung<\/p>\n
