The ACT Container Deposit Scheme (ACT CDS) was introduced by the ACT Government in 2018 as a litter reduction initiative. Participants collect and return their eligible drink containers at an ACT CDS return point for a 10 cent refund on each. For further information about the ACT CDS, please visit actcds.com.au
This lesson plan has been developed by Cool Australia, in collaboration with Exchange for Change, the scheme coordinator for the ACT CDS, as part of a suite of curriculum-linked resources for teachers that support schools’ participation in the scheme and enable teachers to discuss the environmental benefits of the scheme as part of their sustainability lessons.
