Hollywood stars Scarlett Johansson and Eva Mendes are using their sex appeal for a good cause with public service announcements (PSAs) to promote mobile phone recycling.

The campaign is organized by the Environmental Media Association (EMA) and Lionsgate studio, which hope to spread awareness among the starlets’ fans about how recycling can help lessen CO2 emissions by decreasing the energy needed to create new phones.

The Scarlett Johansson fronted PSA, “Answer the Call!” plays off the poster of her upcoming movie “The Spirit,” which co-stars Eva Mendes.

The PSAs will start appearing in People magazine on Friday, September 19.
