A systemic environmental impact metric for companies and investors

环境-社会-治理（ESG）指标作为环境绩效的衡量标准销售，但它们通常跟踪环境风险的暴露，而不是环境影响的产生。该项目旨在为公司活动制定和测试一个以科学为基础的系统性环境影响评分。预期成果包括关于地球系统中跨尺度相互作用的新知识，以及用于评估企业或投资活动对环境的系统性影响的工具，这些活动包括取水、毁林和碳排放。这些成果应能带来惠益，包括改善有关减轻影响、环境质量、生产力和公司环境声誉的业务决策。

Environmental-Social-Governance (ESG) metrics are marketed as measures of environmental performance, but they often track exposure to environmental risk rather than generation of environmental impacts. This project aims to develop and test a science-based, systemic environmental impact score for corporate activities. Expected outcomes include new knowledge of cross-scale interactions in the Earth system and tools to assess a business or investment’s systemic environmental impacts from activities including water extraction, deforestation and carbon emissions. These outcomes should provide benefits including improved business decision-making on impact mitigation, environmental quality, productivity and corporate environmental reputation.
