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.

What’s the business case for ending life on earth?

We need an honest bottom line. Today that bottom line is vastly subsidized. If anyone of us were paying the full cost of oil our bottom lines would be very different. If you internalize the cost of oil, look at the cost of the war in the Middle East or the cost of global warming for future generations, if you internalize those external costs and what you pay, that bottom line would look very different, what ever business you are in.

If we somehow put a value on species extinction and factor that into our costs that bottom line would look very different. IF we put any resource depletion into costs our bottom line would change. So what we have is a dishonest market that does not take into account all the costs when it establishes its prices. We need an honest marketplace before we can let the market work for sustainability rather than against it as it works today.

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."

"Comply" is not a vision.

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.
