本报告按行业、行业组和区域层面汇总了这些成本，展现了这一挑战的真实规模，仅 2021 年的环境负外部性估算即达 3.71 万亿美元。通过将这些环境影响以货币形式表达，本报告在其前作的基础上有所推进，整合了已披露的环境关键绩效指标（EKPIs）以及社会与人力资本议题的相关信息。尽管本报告重点阐述了各类资本的影响，仍有进一步发展的空间，包括将分析扩展至整个价值链，并将估值扩展至社会与人力影响。
The report offers a summary of these costs by sector, sector group and regional levels. It provides a look at the true magnitude of the challenge, estimating environmental negative externalities at $3.71 trillion in 2021 alone. By expressing these environmental impacts in monetary terms, this report advances upon the work of its predecessor by integrating disclosed information on environmental key performance indicators (EKPIs) and social and human capital issues. While this report highlights these capitals impacts, there is still room for further development, including by expanding the analysis to the entire value chain and expanding valuation to social and human impacts.
