‘Buy Clean’ policies have promise, but we first need to know which products are low-carbon

Legislators and advocates are increasingly looking to spur demand for low-carbon products, which is a key step for reducing industrial emissions. In this approach, government purchasing power can help provide a market signal for products with lower embodied carbon (reflecting the impact of all greenhouse gases across extraction, manufacturing, and transportation to the purchaser).
Federal and state efforts have enormous potential, but implementation has proved difficult because key information is often missing. In fact, inadequate data poses a broader challenge and is hampering many efforts to cut carbon.
Data on the carbon content of materials and systems for tracking and transparently reporting information across supply chains are inadequate. There is variation in current rules for reporting, exemptions, and standards and how product lifecycles are estimated. These challenges make harmonization of targets difficult. We must address these barriers if we are to identify, label, and prioritize low-carbon products.
