Welcome to the

2021 International Climate Action Challenge!

Hello fellow eco-enthuiast,

Are you concerned about the state of the planet? Does it seem like our world leaders are always distracted by some short-term problem while ignoring the bigger, critical issues around climate change, the environment, and social justice? 


The predictions for the future of life on the planet is dire. But, that's only if we don't change. Here's the thing...


There is actually a silver lining. We don't have to wait for anyone else to figure it out. We can take responsibility and take action now!


I wasted decades doing stupid stuff, being extremely ineffective. And so has most of humankind! That's what's gotten us into this mess.


But, there is another way. Through decades of on-the-ground experience and through working with hundreds of teams around the world, I found out what actually works.


I distilled those best practices into the book: Climate Action Challenge: A Proven Plan for Launching Your Eco-Initiative in 90 Days.


And we demonstrated those principles by hosting the 2020 International Climate Action Challenge. Over 100 challengers from 20 countries worked to launch their initiatives from September 1 to November 30, 2020. You can #BeTheChange by participating in our 2021 Challenge.


Take a look around:

Thanks for stopping by and I look forward to creating the world we want, together!
