Coca-Cola is a top target for consumer, investor and environmental groups concerned about petroleum-based plastic single-use bottles clogging oceans, among other problems.
The company was the world's worst plastic polluter for the fourth year in a row in 2021, according to the global coalition Break Free From Plastic's annual report released in October.
"We hope that other companies will follow Coke's leadership and set reusable packaging targets," said the group's global corporate campaign coordinator Emma Priestland.
