Coca-Cola, PepsiCo and Nestlé have been accused of “zero progress” on reducing plastic waste, after being named the world’s top plastic polluters for the third year in a row.

Coca-Cola was ranked the world’s No 1 plastic polluter by Break Free From Plastic in its annual audit, after its beverage bottles were the most frequently found discarded on beaches, rivers, parks and other litter sites in 51 of 55 nations surveyed. Last year it was the most frequently littered bottle in 37 countries, out of 51 surveyed.

It was found to be worse than PepsiCo and Nestlé combined: Coca-Cola branding was found on 13,834 pieces of plastic, with PepsiCo branding on 5,155 and Nestlé branding on 8,633.

Coca-Cola came under fire from environmental campaigners earlier this year when it announced it would not abandon plastic bottles, saying they were popular with customers. In March, Coca-Cola, PepsiCo, Nestlé and Unilever were found to be responsible for half a million tonnes of plastic pollution in six developing countries each year, in a survey by NGO Tearfund.
