Real Estate Portfolio Carbon Risk Score (CaRiS)

随着各组织签署净零声明，一系列第三方自愿承诺提供透明度，以及一系列碳计算器、工具和流程在指导和决策方面有所帮助，在cop26之后，建筑环境的脱碳继续受到高度关注。人们理所当然地将如此多的注意力集中在建筑专业人士身上，以及他们在新建筑脱碳决策中的作用，以及在较小程度上的翻新决策。支持ESG透明度和信息披露的绿色融资的增长，使得与建筑环境资产相关的金融服务提供的绿色债券大幅增加。据估计，全英国的建筑价值12万亿英镑（商业和住宅）。其中，住宅行业（包括公寓、酒店在内的多用途住宅）占主导地位，根据第一太平戴维斯的数据，2019年的价值为7.4万亿英镑，2022年估计接近9.0万亿英镑（85%为私人所有）。对于住宅建筑的投资组合，缺乏对运营碳负荷和投资者所承担的隐含碳的可见性或认识。这隐藏着风险，但也蕴含着机遇。金融服务机构需要更好地了解运营碳和隐含碳对与资产相关的气候和环境风险的相对贡献（以及生命周期考虑和翻新干预的影响）。然而，目前还没有一致的方法来做到这一点。CaRiS是一种方法和概念验证工具，使金融服务机构能够更好地了解与建筑环境资产组合相关的实际和运营碳，从而实现有效的风险管理，并在未来管理投资组合时做出更好的决策。该项目将有助于与利益相关者合作，更好地了解具体需求，并根据现有数据集和工具输出开发和测试CaRiS工具的早期原型。将探索材料银行原则，以量化“隐含碳信用”的潜力。这样的信用额度将使客户能够将他们的建筑资产作为有价值的材料银行（而不是隐含的碳负债）来管理。对于经营性碳，我们将超越EPC寻找可以收集的数据源和方法，以提供一致的衡量标准。改善资产运营碳绩效的干预措施（如可再生能源、热能、织物）将与实际产生的碳一起呈现。这两条链结合为资产的碳轨迹（聚合到投资组合中），从而实现碳风险评分概念。

Decarbonising the built environment continues post-COP26 to receive heightened focus as organisations sign net zero declarations, a range of third party voluntary commitments enabling transparency are on offer and an array of carbon calculators, tools and processes help somewhat in guiding and in decision making. Rightly so much attention has focused on construction professionals and their role in decision making to decarbonise new build and, to a lesser extent, refurbishment.The growth in green financing that supports ESG transparency and disclosure has seen a huge upshift in the green bonds offered by financial services associated with the built environment assets. Buildings are estimated to be worth \>£12tn across the UK (commercial, residential). Within this the residential sector (multi-occupancy, including apartments, hotels) dominates, which according to Savills in 2019 was worth £7.4tn and in 2022 is estimated close to £9.0tn (85% privately owned).For a portfolio of residential buildings there is a lack of visibility or awareness of the operational carbon load and the embodied carbon an investor is taking on. This conceals risks, but also opportunities. Financial services organisations need to better understand the relative contributions that operational and embodied carbon make on the climate and environmental risk associated with assets (and the impact that lifecycle considerations, and refurbishment interventions have). However, there is currently no consistent methodology to do this.CaRiS is a methodology and proof-of-concept tool that enables financial services organisations to better understand embodied and operational carbon associated with a portfolio of built environment assets, enabling effective risk management and better decisions in managing portfolios in future.The project will enable work with stakeholders to better understand the specific need, and to develop and test an early prototype of the CaRiS tool drawing upon existing data sets and tool outputs. The materials bank principle will be explored to quantify potential for an 'embodied carbon credit'. Such a credit would enable clients to manage their built assets as valuable materials banks (rather than embodied carbon liabilities). For operational carbon we will look beyond EPC for data sources and approaches that can be harvested to provide a consistent measure. Interventions (e.g. renewables, heat, fabric) to improve the assets operational carbon performance will be presented alongside embodied carbon incurred. The two strands combine as a carbon trajectory for the asset (aggregated into the portfolio) enabling a carbon risk score concept.
