Impact-weighted accounts are line items on a financial statement, such as an income statement or a balance sheet, which are added to supplement the statement of financial health and performance by reflecting a company’s positive and negative impacts on employees, customers, the environment and the broader society. We develop a methodology to derive comparable and scalable monetized environmental impact estimates by applying characterization pathways and monetization factors to organization level environmental outputs, including carbon emissions, water use, and other emission types. Included are a number of guidance documents, data and visualization tools.
