More than 100 Olympic athletes have called on Coca-Cola and Pepsi to stop selling single-use plastic bottles and promote reusable products when sponsoring sporting events, according to Politico.

The push comes ahead of the 2024 Paris Olympics and Paralympics starting on July 26, which Coca-Cola is sponsoring.

In a letter sent Wednesday to the CEOs of the Coca-Cola Company, its European subsidiary Coca-Cola Europacific Partners and U.S. rival PepsiCo, 102 current and former Olympians, 22 of whom are competing in Paris, are urging the companies to end the plastic pollution “in the spirit of the Olympics and sport”.

Signatories include French windsurfer gold medalist Charline Picon, Irish equestrian silver medalist Sarah Ennis and American swimmer and two-time Olympic gold medalist Zach Apple, as well as athletes from Germany, Sweden, Poland, Nigeria and Mexico. Nine international sports organizations also signed the letter.

The Games “will be the perfect opportunity for you and your companies to drive a radical change in the way the world understands packaging and light the torch for reuse,” the letter says.

Coca-Cola is the world’s top plastic polluter, according to environmental NGO Break Free from Plastics’ Brand Audit 2023. In 2023 Paris Mayor Anne Hidalgo announced a ban on single-use plastics at the games, but French media reported that 40% of drinks will be sold in plastic bottles.
