In 2002, EPA established a voluntary program called the Climate Leaders Program (CL Program) designed for organizations to complete a corporate greenhouse gas (GHG) inventory, set a goal for reducing GHG emissions, and achieve that goal. The program was never implemented as a product labeling program. In 2010, EPA announced the program’s phase out. This study examines whether the CL Program could have been effectively used as a consumer product labeling program to assist consumers in choosing products manufactured by firms that have voluntarily set and achieved targeted GHG emission reductions.
