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.

Business can be a source of progressive change.

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

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.

I like that Ben & Jerry's is willing to speak out about social and political issues that aren't always safe - but are the right thing to do.

We measured our success not just by how much money we made, but by how much we contributed to the community. It was a two-part bottom line.

One of the great things about Ben & Jerry's for me is that not only is it delicious, but I get it for free.
