A bill to direct the Administrator of the Environmental Protection Agency to conduct a study, and publish guidance on, calculating and reporting scope 3 emissions.

S. 3928 would direct the Environmental Protection Agency to conduct a comprehensive study on how to calculate and report scope 3 emissions. Scope 3 emissions refer to indirect greenhouse gas emissions from a company's value chain, such as emissions from suppliers, product transportation, and customer use of products. If enacted, this bill would result in the EPA publishing guidance to help businesses understand and measure these emissions more consistently.

The practical impact for citizens would be increased transparency about the full environmental footprint of companies and their products. Standardized EPA guidance on scope 3 emissions could help consumers make more informed purchasing decisions and enable investors to better assess companies' climate risks. Businesses would have clearer standards for measuring and reporting these emissions, though compliance requirements would depend on how the EPA implements the guidance.

Currently, the bill has been introduced in the Senate and referred to committee for consideration. It has not yet been voted on by the full chamber.
