...there is no more strategic issue for a company, or any organization, than its ultimate purpose. For those who think business exists to make a profit, I suggest they think again. Business makes a profit to exist. Surely it must exist for some higher, nobler purpose than that.

The status quo is a product of our culture or our culture is a product of the status quo - I'm sure which is the effect and which is the product - there is probably a feedback loop there that is mutually reinforcing. But we have a culture that says "Hey, look around. This place called Earth was created for you and you can do anything you want with it."

We really began to think in different ways about our business in terms of climbing this mountain and it became very clear very quickly this was the smart thing to do. Not only did we start to generate answers for those customers, they embraced us for what we were trying to do. The goodwill in the market place has just been stunning. The rest of the business case is pretty simple. I cost it down not up.

I always make the business case for sustainability. It's so compelling. Our costs are down, not up. Our products are the best they have ever been. Our people are motivated by a shared higher purpose - esprit de corps to die for. And the goodwill in the marketplace - it's just been astonishing.

"Comply" is not a vision.

One of the biggest things that needs to change is the educational system. Universities are still teaching a system to students that destroys the biosphere.

I used to think that my job didn't have anything to do with the environment. Then I realized that my job, as well as everyone else's job, impacts the environment in some way. And now advocating for sustainability has become my No. 1 responsibility.
