AT&T continues to strive to improve the environmental performance of AT&T-branded mobile devices. Building on its existing efforts, AT&T created a consumer-friendly and easy-to-understand rating system that will serve as a way for consumers to make more informed choices by allowing them to better understand important environmental attributes of AT&T-branded mobile devices. Now, AT&T consumers will see the new Eco-Rating information on new AT&T-branded post-paid handsets devices added to the portfolio along with many devices from the existing product line.
