Don't just do something because it's a trendy idea and will make you a lot of money. The reason I say that is because any kind of venture involves going through difficult times. If you're doing something you are passionate about and really believe in, then that will carry you through.

Business can be a source of progressive change.

Recycling, packaging, businesses are changing all of those things because that's what consumers want.

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

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.

If you open up the mind, the opportunity to address both profits and social conditions are limitless. It's a process of innovation.

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.

Startups are often very undercapitalised, but I found that to be very beneficial because it forces you not to throw money at problems. Instead, you learn all the nuts and bolts of what you're doing and become an expert.

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.

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.

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.

You know, I get frustrated with our country's administration, which is really the people who are not acknowledging global warming. I mean, it's accepted by scientists around the world, scientists in our country and it's accepted by every country around the world with the exception of the United States.

I'm a pretty laid-back kind of guy. What I've always wanted to do is set up situations in our company where if people who worked there needed help, we would try to help them, and at the same token if the company needed help from people, they would help us. A kind of give and take.

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.

If your support the community, they will support you.

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.
