In a perfect world global emissions would have peaked already. In a semi-perfect world we will peak on Dec. 31, 2020. The fact is, that's going to be difficult. We know that it's going to get more and more expensive the longer we delay.

Carbon neutrality is going to be so standardized that you will look at anything that is not carbon neutral and go, "where the hell did that monster come from?" It's exciting.

When you have a vision of where you need to go, it sounds utopian. But when you get to the tipping point, your understanding switches.

Think global, act local.

I still do not understand why we don't have people on the streets every single day raising their voices for climate.

We have to get to the point where each individual, each corporation, each community chooses low carbon, because it makes fundamental sense. It should become a no-brainer.
