Businesses can lead with their values and make money, too. You don't have to simply be purely profit-driven. You can integrate social and environmental concerns into a business, be a caring business, be a generous business and still do very well financially.

So much business is based on the belief that we should do whatever we can within legal limits to make as much money as we can. Ben & Jerry's was based on values, and we try to operate a business that not just sells ice cream but partners with all our stakeholders - whether that's suppliers or customers - to bring about a more sustainable world.

One out of every 100 families in Vermont was a part owner of Ben and Jerry's.

Ben & Jerry's evolved into what it is doing and is trying to transition its supply chain, but this is essentially retrofitting. In the social enterprise movement, we see companies whose essence, the products they make, the reason they exist from day one, is because these people see something out in the world that they cannot accept.

Ice cream is the perfect buffer, because you can do things in a somewhat lighthearted way. Plus, people have an emotional response to ice cream; it's more than just food. So I think when you combine caring, and eating wonderful food, it's a very powerful combination.

Businesses typically look at issues like price, quality, time of delivery. They don't often think about social and environmental impact because they're focused on their financial bottom line.

It's good to stand for something, to believe in something and base your business on values.
