The brewer is spending £7.5m over the next two years to make the changes on its Carling and Coors Light brands.
As part of the commitment, 100 per cent recyclable cardboard sleeves will replace plastic rings on cans and plastic film wrap will be removed from large multipacks by the end of March 2020.
By 2025 the brewer says that 100% of its packaging will be reusable, recyclable, compostable or biodegradable. It is also strengthening its goals to drive down packaging emissions, use more recycled materials in its plastic packaging and improve recycling solutions in its key markets.
"As a global brewer with a strong family heritage, we have always taken seriously our responsibility to brew a more sustainable future," said Molson Coors CEO, Mark Hunter.
"Plastic waste poses a clear environmental challenge, and as a consumer-packaged goods company, we play an important role in helping to solve the global waste crisis."
