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.

# Plain Language Summary of S 3928 **What the Bill Would Do:** This bill would require the Environmental Protection Agency (EPA) to study and create guidance on how companies should measure and report "scope 3 emissions"—greenhouse gases produced indirectly through a company's supply chain and product use. For example, scope 3 emissions include pollution from shipping products, customer use of products, or waste disposal. Currently, there's no standardized federal approach, so companies use different methods, making it hard to compare their environmental impact. **Who It Affects:** The bill primarily affects businesses and corporations that would need to follow the EPA's new guidance for measuring and reporting these emissions.

It could also impact consumers and investors who rely on emissions data to make purchasing and investment decisions. **Current Status:** The bill was introduced in the 119th Congress by Senator Adam Schiff (D-CA) and is currently in committee, meaning it hasn't been voted on by the full Senate yet. It has not advanced further in the legislative process.
