The ECO Challenge is a great way to get involved in becoming more sustainable. It’s an easy-to-use tool designed to help all ACT residents become more sustainable in their daily lives. Different challenges are up for grabs and each has great tips and advice on how to complete them. They’re all self nominated and a whole lot of fun. With each challenge, you compete against yourself, your friends or a team from work or your community and earn emission savings for your efforts.
