Summary.

An increasing number of companies are using the E-liability carbon-accounting method as an important tool for tracking progress toward reducing global emissions in their supply chains. The system does not require formal accounting for downstream emissions—those occurring after a company sells its products to immediate customers, for several good reasons.

Certain companies, however, are accountable for disclosing downstream emissions generated by consumers’ use of their products. Three principles govern accountability: (1) Downstream accountability is limited to companies whose products are directly used by end customers. (2) Accountability for B2C companies is limited to cases where a reasonable causal link exists between product-design decisions and the downstream emissions generated by consumers. (3) Companies are accountable for disclosing emissions produced per unit of use, not for total emissions.

This article presents the principles and explains how and to what standards of reliability the companies should disclose downstream emissions.

Companies attempting to address climate change by decreasing their carbon footprints face the challenge of measuring how their operational, product design, and purchasing decisions affect the emissions generated in their supply chains. In a previous article, we introduced a robust carbon-accounting method (the E-liability system) for just this purpose. By applying this system, companies can produce environmental (or E-) ledgers of their own emissions—and those of their supply chains—that are as accurate, timely, comparable, and auditable as financial statements. An increasing number of companies are finding that the E-liability approach is an important tool for themselves, their customers, and other stakeholders in tracking real progress toward reducing global emissions in their supply chains.
