Ben & Jerry's is an indulgent dessert that should be eaten in moderation. You should not be replacing more than one meal a day with ice cream. We do not consider a pint or a tub of ice cream to be a single serving.

Ben & Jerry's evolved into what it is doing and is trying to transition its supply chain, but this is essentially retrofitting.

Look at your business and the activities that you undertake. Then, start to think about not just your economic concerns, but about social and environmental impacts that businesses have.
