Carbon in your body - that's good thing. In a tree, it's good. In the atmosphere, it's a bad. Nature wants to sequester carbon in biota. And when we burn it, we release it. It's the wrong system.

I think as designers we realize design is a signal of intention, but it also has to occur within a world and we have to understand that world in order to imbue our designs with inherent intelligence.

You need that same creative force that exists in a building like Disney [Walt Disney Concert Hall] to actually tackle that most prosaic of problems.

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.

If we think about things having multiple lives, cradle to cradle, we could design things that can go back to either nature or back to industry forever.

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.

We prefer to talk about 100% renewable instead of zero carbon. When you say zero carbon, you are not positively defined.
