In 2004, Connecticut enacted efficiency standards legislation through Public Act 04-85 covering eight different appliances. These appliance standards are estimated to reduce the state's carbon emissions by over 74,000 metric tons. In 2007, PA 07-242 expanded Connecticut's regulations to include nine additional product classes, an additional emission reduction of 84,000 metric tons of carbon, and directed the Office of Policy and Management to establish regulations.

Connecticut’s standards apply only to products sold for final sale in the state. They do not apply to products manufactured in Connecticut and sold outside the state, products manufactured outside Connecticut and sold at wholesale inside the state for final retail sale and installation outside the state, products installed in mobile manufactured homes at the time of construction, or products designed exclusively for installation and use in recreational vehicles.
