Portland coffee company Nossa Familia has been experimenting with a surcharge for takeaway coffees in paper cups at one of their three Portland locations. Last week, they rolled it out at all three stores in the Portland area. Customers who ask for a disposable cup will be asked to pay 25 cents extra. This B Corp is hoping that it creates a wave of change, pushing customers to invest in a reusable cup or take a few minutes to enjoy a coffee. Could it be the beginning of a wider movement?
