Believe it or not, I come offering a solution to a very important part of this larger problem, with the requisite focus on climate. And the solution I offer is to the biggest culprit in this massive mistreatment of the earth by humankind, and the resulting decline of the biosphere. That culprit is business and industry. Which happens to be where I have spent the last 52 years since my graduation from Georgia Tech in 1956. As an industrial engineer, cum aspiring and then successful entrepreneur. After founding my company Interface from scratch in 1973, 36 years ago, to produce carpet tiles in America for the business and institution markets, and shepherding it through start-up and survival to prosperity and global dominance in its field, I read Paul Hawkins' book, The Ecology of Commerce, the summer of 1994. In his book Paul charges business and industry as, one, the major culprit in causing the decline of the biosphere, and, two, the only institution that is large enough and pervasive enough, and powerful enough, to really lead humankind out of this mess. And by the way he convicted me as a plunderer of the earth.
And I then challenged the people of Interface, my company, to lead our company and the entire industrial world to sustainability. Which we defined as eventually opperating our petroleum intensive company in such a way as to take from the earth only what can be renewed by the earth naturally and rapidly, not another fresh drop of oil, and to do no harm to the biosphere. Take nothing. Do no harm. I simply said, "If Hawkins is right and business and industry must lead, who will lead business and industry? Unless somebody leads, nobody will." It's axiomatic. Why not us? And thanks to the people of Interface, I have become a recovering plunderer.
(Laughter)
(Applause)
I once told a Fortune Magazine writer that someday people like me would go to jail. And that became the headline of a Fortune article. They went on to describe me as America's greenest CEO. From plunderer to recovering plunderer, to America's greenest CEO, in five years. That frankly was a pretty sad commentary on American CEOs in 1999. Asked later in the Canadian documentary, The Corporation, what I meant by the "go to jail" remark, I offered that theft is a crime. And theft of or children's future would someday be a crime. But I realized for that to be true, for theft of our children's future to be a crime, there must be a clear demonstrable alternative to the take-make-waste industrial system that so dominates our civilization, and is the major culprit, stealing our children's future, by digging up the earth and converting it to products that quickly become waste in a landfill or an incinerator. In short, digging up the earth and converting it to pollution.
According to Paul and Anne Ehrlich and a well known environmental impact equation, impact -- a bad thing -- is the product of population, affluence and technology. That is, impact is generated by people, what they consume in their affluence, and how it is produced. And though the equation is largely subjective, you can perhaps quantify people, and perhaps quantify affluence, but technology is abusive in too many ways to quantify. So the equation is conceptual. Still it works to help us understand the problem.
So we set out at Interface, in 1994, to create an example, to transform the way we made carpet. A petroleum intensive product for materials as well as energy. And to transform our technologies so they diminished environmental impact, rather than multiplied it. Paul and Anne Ehrlich's environmental impact equation: I is equal to P times A times T. Population, affluence and technology. I wanted Interface to rewrite that equation so that it read I equals P times A divided by T. Now, the mathematically minded will see immediately that T in the numerator increases impact -- a bad thing. But T in the denominator decreases impact. So I ask, "What would move T, technology, from the numerator, call it T1, where it increases impact, to the denominator, call it T2, where it reduces impact?
I thought about the characteristics of first industrial revolution, T1, as we practiced it at Interface, and it had the following characteristics. Extractive: taking raw materials from the earth. Linear: take, make, waste. Powered by fossil fuel derived energy. Wasteful: abusive and focused on labor productivity. More carpet per man hour. Thinking it through, I realized that all those attributes must be changed to move T to the denominator. In the new industrial revolution extractive must be replaced by renewable, linear by cyclical, fossil fuel energy by renewable energy, sunlight. Wasteful by waste-free. And abusive by benign. And labor productivity by resource productivity. And I reasoned that if we could make those transformative changes, and get rid of T1 altogether, we could reduce our impact to zero, including our impact on the climate. And that became the Interface plan in 1995. And has been the plan ever since.
We have measured our progress very rigorously. So I can tell you how far we have come in the ensuing 12 years. Net greenhouse gas emissions down 82 percent in absolute tonnage. (Applause) Over the same span of time sales have increased by two thirds and profits have doubled. So an 82 percent absolute reduction translates into a 90 percent reduction in greenhouse gas intensity relative to sales. This is the magnitude of the reduction the entire global technosphere must realize by 2050 to avoid catastrophic climate disruption. So the scientists are telling us. Fossil fuel usage is down 60 percent per unit of production, due to efficiencies in renewables. The cheapest, most secure barrel of oil there is is the one not used through efficiencies. Water usage is down 75 percent in our world-wide carpet tile business. Down 40 percent in our broadloom carpet business, which we acquired in 1993 right here in California, City of Industry, where water is so precious. Renewable or recyclable materials are 25 percent of the total, and growing rapidly. Renewable energy is 27 percent of our total, going for 100 percent. We have diverted 148 million pounds -- that's 74,000 tons -- of used carpet, from landfills. Closing the loop on material flows through reverse logistics and post-consumer recycling technologies that did not exist when we started 14 years ago.
Those new cyclical technologies have contributed mightily to the fact that we have produced and sold 85 million square yards of climate-neutral carpet since 2004. Meaning no net contribution to global climate disruption in producing the carpet throughout the supply chain, from mine and well head clear to end-of-life reclamation. Independent third-party certified. We call it Cool Carpet. And it has been a powerful marketplace differentiator, increasing sales and profits. Three years ago we launched carpet tile for the home, under the brand Flor, misspelled F-L-O-R. You can point and click today at Flor.com and have Cool Carpet delivered to your front door in five days. It is practical, and pretty too.
(Laughter)
(Applause)
We reckon that we are a bit over halfway to our goal -- zero impact, zero footprint. We've set 2020 as our target year for zero, for reaching the top, the summit of Mount Sustainability. We call this Mission Zero. And this is perhaps the most important facet. We have found Mission Zero to be incredibly good for business. A better business model. A better way to bigger profits. Here is the business case for sustainability. From real life experience, costs are down, not up, reflecting some 400 million dollars of avoided costs in pursuit of zero waste. The first face of Mount Sustainability. This has paid all the costs for the transformation of Interface.
And this dispels a myth too, this false choice between the environment and the economy. Our products are the best they've ever been, inspired by design for sustainability, an unexpected wellspring of innovation. Our people are galvanized around this shared higher purpose. You can not beat it for attracting the best people and bringing them together. And the goodwill of the marketplace is astonishing. No amount of advertising, no clever marketing campaign at any price, could have produced or created this much goodwill. Costs, products, people, marketplaces. What else is there? It is a better business model.
And here is our 14-year record of sales and profits. There is a dip there, from 2001 to 2003: a dip when our sales, over a three year period, were down 17 percent. But the marketplace was down 36 percent. We literally gained market share. We might not have survived that recession but for the advantages of sustainability. If every business were pursuing Interface plans would that solve all our problems? I don't think so. I remain troubled by the revised Ehrlich equation, I equals P times A divided by T2. That A is a capital A, suggesting that affluence is an end in itself. But what if we reframed Ehrlich further? And what if we made A a lowercase 'a,' suggesting that it is a means to an end, and that end is happiness. More happiness with less stuff.
You know that would reframe civilization itself -- (Applause) and our whole system of economics, if not for our species then perhaps for the one that succeeds us. The sustainable species, living on a finite earth. Ethically, happily and ecologically in balance with nature and all her natural systems for a thousand generations, or 10,000 generations. That is to say, into the indefinite future. But does the earth have to wait for our extinction as a species? Well maybe so. But I don't think so.
At Interface we really intend to bring this prototypical sustainable, zero-footprint industrial company fully into existence by 2020. We can see our way now. Clear to the top of that mountain. And now the challenge is in execution. And as my good friend and adviser Amory Lovins says, "If something exists, it must be possible." (Laughter) If we can actually do it, it must be possible. If we, a petro-intensive company can do it, anybody can. And if anybody can, it follows that everybody can.
Hawking fulfilled business and industry, leading humankind away from the abyss. Because with continued unchecked decline of the biosphere, a very dear person is at risk here. Frankly, an unacceptable risk. Who is that person? Not you. Not I. But let me introduce you to the one who is most at risk here. And I myself met this person in the early days of this mountain climb. On a Tuesday morning in March of 1996 I was talking to people, as I did at every opportunity back then. Bringing them along and often not knowing whether I was connecting. But about five days later back in Atlanta, I received an email from Glenn Thomas, one of my people in the California meeting. He was sending me an original poem that he had composed after our Tuesday morning together. And when I read it it was one of the most uplifting moments of my life. Because it told me, by God, one person got it. Here is what Glenn wrote. And here is that person, most at risk. Please meet "Tomorrow's Child."
"Without a name, an unseen face, and knowing not your time or place,
Tomorrow's child, though yet unborn, I met you first last Tuesday morn.
A wise friend introduced us two. And through his sobering point of view
I saw a day that you would see, a day for you but not for me.
Knowing you has changed my thinking. For I never had an inkling
that perhaps the things I do might someday, somehow threaten you.
Tomorrow's child, my daughter, son,
I'm afraid I've just begun to think of you and of your good,
though always having known I should.
Begin, I will.
The way the cost of what I squander, what is lost,
if ever I forget that you will someday come and live here too."
Well, every day of my life since, "Tomorrow's Child" has spoken to me with one simple but profound message, which I presume to share with you. We are, each and every one, a part of the web of life. The continuum of humanity, sure. But in a larger sense, the web of life itself. And we have a choice to make during our brief brief visit to this beautiful blue and green living planet. To hurt it or to help it. For you, it's your call.
Thank you.
(Applause)

This is a work in process based on some comments that were made at TED two years ago about the need for the storage of vaccine. (Music) [ On this planet ] [ 1.6 billion people ] [ don't have access to electricity ] [ refrigeration ] [ or stored fuels ] [ this is a problem ] [ it impacts: ] [ the spread of disease ] [ the storage of food and medicine ] [ and the quality of life ] [ so here's the plan: inexpensive refrigeration that doesn't use electricity ... ] [ ... propane, gas, kerosene or consumables ] [ time for some thermodynamics ] [ And the story of the Intermittent Absorption Refrigerator ]


So 29 years ago, I had this thermo teacher who talked about absorption and refrigeration. It's one of those things that stuck in my head. It was a lot like the Stirling Engine: it was cool but you didn't know what to do with it. And it was invented in 1858 by this guy Ferdinand Carre, but he couldn't actually build anything with it because of the tools of the time.

This crazy Canadian named Powell Crosley commercialized this thing called the Icyball in 1928, and it was a really neat idea, and I'll get to why it didn't work, but here's how it works. There's two spheres and they're separated in distance. One has a working fluid, water and ammonia, and the other is a condenser. You heat up one side, the hot side. The ammonia evaporates and it re-condenses in the other side. You let it cool to room temperature, and then, as the ammonia re-evaporates and combines with the water back on the erstwhile hot side, it creates a powerful cooling effect. So it was a great idea that didn't work at all: it blew up. Because using ammonia you get hugely high pressures if you heated them wrong. It topped 400 psi. The ammonia was toxic. It sprayed everywhere. But it was kind of an interesting thought.

So, the great thing about 2006 is there's a lot of really great computational work you can do. So we got the whole thermodynamics department at Stanford involved. A lot of computational fluid dynamics. We proved that most of the ammonia refrigeration tables are wrong. We found some non-toxic refrigerants that worked at very low-vapor pressures. Brought in a team from the UK -- there's a lot of great refrigeration people, it turned out, in the UK -- and built a test rig, and proved that in fact we could make a low pressure, non-toxic refrigerator.

So this is the way it works. You put it on a cooking fire. Most people have cooking fires in the world, whether it's camel dung or wood. It heats up for about 30 minutes, cools for an hour. Put it into a container and it will refrigerate for 24 hours. It looks like this. This is the fifth prototype. It's not quite done. Weighs about eight pounds, and this is the way it works. You put it into a 15-liter vessel, about three gallons, and it'll cool it down to just above freezing, three degrees above freezing, for 24 hours in a 30 degree Celsius environment. It's really cheap. We think we can build these in high volumes for about 25 dollars, in low volumes for about 40 dollars. And we think we can make refrigeration something that everybody can have.

Thank you. (Applause)
