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.

Now, when we face a problem like global warming, and you understand that the biggest impacts on global warming come from business and industry, I think business needs to take a leading role.

It's pretty rare to have CEOs or high level executives at big companies who are social activists. They tend not to be drawn to those areas of life.

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.

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.

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.

If you support the community, they will support you.
