In a public letter to stakeholders on Tuesday, CEO Kevin Johnson said the company plans to shift away from single-use to reusable packaging, and invest in better waste-management.

Starbucks did not say exactly when it would move away from single-use cups and plastic.

It’s also promising more plant-based foods on its menu.

That trend is growing fast in the food industry.

The past year has seen the rise of Beyond Meat and Impossible Foods. And several major restaurants, like Burger King and Dunkin' Donuts, have raced to offer such products.

For now, the world's largest coffee chain has laid out targets for 2030 including cutting the landfill waste from its stores by half.

But Starbucks, which uses about 6 billion cups a year, has failed in the past to meet some of its own environmental goals… including making 25% of its cups reusable by 2015.
