Starbucks has announced that customers can now bring their own personal cups to all visits, including drive-through and mobile orders. This move is part of the company's commitment to reduce waste by 50 percent by 2030, and customers will receive a 10 cent discount and 25 bonus stars for U.S. Starbucks rewards when they bring their own cup. Starbucks is also implementing other sustainability efforts, such as a 5p charge for disposable cups in the UK and Ireland, and a cup-sharing program in Seattle.
