The reuse of consumer materials, such as bags, cartons, containers and the like, or the participation in more sustainable activities, such as car pooling, are tracked in conjunction with a sponsoring entity, such as a commercial establishment where the materials are reused by an individual, and that reuse is tracked and credited as an economic value. The economic value is redeemable with a participant, such a merchant where the materials are reused, or another participant merchant, or a business or employer which sponsors such reuse. The economic value may be redeemed by an individual participant, or may be donated, sold, bartered or exchanged. Groups may participate in the reuse of materials, such as by joining together where the reuse of materials by any member of the group accumulates economic value for the group or a designee of the group, such as a charity.
