"Known for its iconic foam cups, this chain is phasing them out in favor of double-walled paper cups — a transition announced in 2018 and accelerated with a rollout replacing foam across New England by December 1, with the new cups arriving elsewhere soon. The company is running a campaign to help long-time customers adapt to losing the foam’s insulating benefit for iced drinks and notes the new cups are certified to the Sustainable Forestry Initiative Standard. The change is framed as both a business response to local foam bans and an environmental move, but experts point out that paper cups are typically plastic-lined and can be just as likely to end up in landfills, may have higher manufacturing impacts than foam, and in some circumstances foam could outperform other options; whether the switch will be a net environmental benefit remains unclear." - Jaya Saxena
