Last January, more than 3,000 of you signed up for No Impact Week, an experiment that challenged you to live a radically greener and more connected lifestyle—for just one week.

as an individual

or as a group!

Now it's time to join us again and round out the summer with the No Impact Week carbon cleanse, September 18-25. YES!, the No Impact Project, and you will join forces with Bill McKibben and for Moving Planet Day on September 24—a massive global volunteer day.

During No Impact Week, you'll have the chance to participate on your own or as a team, taking on challenges and competitions like eating locally, lowering your energy use, and meeting your neighbors. If you don't want to go it alone, you can even sign up with an already existing group.

Whether it's your first, second, or tenth time around, you'll answer questions like:

  • How well can I live without modern “conveniences?”
  • Which expenses actually make me happy, and improve my family's quality of life?
  • Which ones just eat away at my time and money?
  • What does my carbon footprint really look like?

Join HERE and experiment along with us, and then share what you learn!

For more details about specific themes and challenges, check out our coverage of January's No Impact Week.

The No Impact Project was conceived by Colin Beavan, following the success of his blog, book, and film, No Impact Man. He chronicled his family’s year-long experiment in zero-waste living in New York City, and created a weeklong experiment based on his experiences.

How It Works

You try the experiment, see if it changes your life, tell your friends to try it, see if it changes theirs...

Sometimes the hardest part of changing our lives and world is knowing that it's possible.

1) Take a brief post-experiment eco-lifestyle survey (we will send this to you).

2) Sign up to become a No Impact Ambassador in your community.

3) Six-months later the No Impact Project will follow up with you to gauge the long-term impact of the Experiment.

Please note that we do not want you to feel limited or overwhelmed by the ideas promoted by the No Impact Experiment.  Define your experience.  Do as much as you can and adapt it to your life. Like most challenges, the more you put into this, the more you’ll get out of it.

Please follow us on Facebook and Twitter and visit our website for more information in the lead-up to September 18, as well as original YES! content on low-impact living.  We hope to see you there!
