Regulators in the US and Europe are increasingly focusing on scope 3 emissions, which include indirect emissions from a company's supply chain. Pending legislation may soon require companies to measure and report scope 3 greenhouse gas emissions, including those from trucks. Measuring scope 3 emissions, especially for complex products like cars with numerous components and suppliers, presents challenges due to the lack of universally accepted standards. However, truck transportation, a significant source of scope 3 emissions, offers an opportunity for establishing efficient, comparable, and transparent reporting standards. Existing approaches to measuring trucking emissions, such as using a single emissions factor, suffer from deficiencies in accuracy, alignment with federal policies, and incentivizing sustainability efforts.
