Real Estate Portfolio Carbon Risk Score (CaRiS)

COP27强调了建筑环境的脱碳，这是在减轻气候危机影响和实现社会零碳途径方面取得进展的基础。一系列有助于实现透明度的第三方自愿承诺正在提供，一系列碳计算器、工具和程序在一定程度上有助于指导和决策。如此多的注意力集中在建筑专业人士及其在决策中的作用，以减少新建筑的碳化，并在较小程度上，翻新。对于住宅建筑的投资组合，缺乏可见性或意识，运营碳负荷和投资者正在承担的隐含碳。这隐藏了风险，但也掩盖了机会。金融服务组织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建筑改善干预的影响）。CaRiS是一种方法和概念验证工具，可为住宅投资组合的具体和运营碳带来可见性，使金融部门能够有效地进行风险管理，并在未来管理投资组合时做出更好的决策。我们的第1阶段项目构建了一个概念验证工具，这是该项目的起点。我们将与金融服务业的利益相关者合作，提供所需的功能和用户界面。我们收集的用户洞察力将指导技术模型的构建，开发和测试CaRiS工具在现有数据集上的迭代。将探索循环经济方法，以量化“隐含碳信用”的潜力，使客户能够将其建筑资产作为有价值的材料银行（而不是隐含碳负债）进行管理。对于运营碳排放，我们继续在EPC之外寻找数据来源和方法，以提供一致的衡量标准。干预措施（例如，可再生能源、热能、织物），以改善资产的运营碳绩效，将与产生的隐含碳一起提出。这两条链联合收割机作为碳头寸和资产的路径（汇总到投资组合中），从而实现碳风险评分概念。风险评分考虑了这一碳排放状况以及改进的任何限制、剩余的设计寿命、深入翻修的必要性以及对照国家绩效目标和实体数据库的基准。

Decarbonising the built environment is being highlighted at COP27 as fundamental to make progress towards mitigating the impacts of the climate crisis and enabling zero carbon pathways for society. 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.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 obscures 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 building improvement interventions have). However, there is currently no consistent methodology to do this.CaRiS is a methodology and proof-of-concept tool that brings visibility to embodied and operational carbon associated with a residential portfolio, enabling the financial sector to effectively risk manage and make better decisions in managing portfolios in future. Our Phase 1 project built a proof-of-concept tool which is the starting point for this project. We will work with stakeholders from the financial services sector to deliver the functionality and user interface required. The user insight we gather will direct the build of the technical models, develop and test the iterations of the CaRiS tool drawing upon existing data sets. A circular economy approach will be explored to quantify potential for an 'embodied carbon credit' to enable clients to manage their built assets as valuable materials banks (rather than embodied carbon liabilities). For operational carbon we continue to 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 position and pathway for the asset (aggregated into the portfolio) enabling a carbon risk score concept. The risk score considers this carbon position alongside any limitations for improvement, the remaining design life, the need for deeper refurbishment and benchmarks against national performance targets and entity databases.
