We are proposing buildings that, like trees, are net energy exporters, produce more energy than they consume, accrue and store solar energy, and purify their own waste, water and release it slowly in a purer form.

We have carbon in the atmosphere. That is a material in the wrong place problem. It's just like what I said about the lead. Lead in the biosphere is not good. Carbon in the atmosphere (over natural levels) is a problem.

Our goal is a delightfully diverse, safe, healthy, and just world, with clean air, water, soil and power – economically, equitably, ecologically and elegantly enjoyed.

The surest way to heal an eco-system is to connect it to more of itself.

If you don't like carbon, if you want to be zero carbon, then you might as well shoot yourself, dry up and blow away because you are carbon.

I'd so much rather have exciting architecture that causes one to stop, breathe, and reflect on the potential of the human mind, the craft, and exploring things.

In planetary terms, we're all downstream.
