The new game - Emission Impossible - was designed by Cosmic Enterprises, a company formed by a team of 11 school girls as part of their Young Enterprise Programme.
Gibsons managing director, Nick Wright and marketing director, Kate Armitage recently visited the students to sign the deal and meet the team.
Kate Armitage, commented: "We are absolutely delighted to be working with Cosmic Enterprises and to be taking their fantastic game to market.
"Emission Impossible highlights an extremely important issue for children today and encourages them to be more environmentally aware whilst having lots of fun."
The game will be launched in autumn with the support of a nationwide PR campaign.
