Starbucks and The Coffee Club will now give you 50c off the price of your coffee if you remember to bring a reusable cup.
Previously, Starbucks gave a 40c discount to environmentally conscious coffee drinkers – but this will now be increased to 50c.
The Coffee Club has also jumped on the eco-train and will be offering 50c discounts for consumers who bring in their own cups.
The news comes weeks after Australian supermarkets banned bags.
