I’m concerned that our CO2 emissions could have rough consequences for the next generation, and that time is running out to address the problem. That said, I’m optimistic that we can do something about it. The past year has seen a remarkable increase in awareness, corporate initiatives, technical innovation, and policy. To win, we’ll need to couple all of these advances with personal action on a massive scale.


A few friends and I created Carbonrally in late 2007. I have a dozen years of experience in corporate strategy and new product development, and advanced degrees in business and environmental economics from Duke University. My favorite job these days is being the dad of two little kids. My time outdoors with them is motivating me to do something about climate change.


I’ve realized it’s time to RALLY UP. I hope you will join me.
