Frequently Asked Questions

What Happened last year?

Your actions last year contributed to reducing 488 tons of CO2 community-wide! That's the equivalent of taking 105 cars off the road for one year, a big impact. We want you to help us make an impact on our climate action goals again and that's why we've quadrupled our goal for reducing emissions this year to 1,000 tons of CO2. This is ambitious, but we think Fort Collins can do it and we're going to need your help to get there!

What about all the actions I took last year?

If you took actions last year they will remain as "complete" in and are something to be proud of. However, your progress last year will not contribute toward your 5,000 point goal for 2022. This is because we want everyone to challenge themselves each year to take their climate action to the next level.

What's new this year?

  • Colorado State University is hosting a month of fun Earth Day-focused activities that are open to both students and the community in March. We'll share more as we get closer.
  • We are launching a Team Leader program for those who want to be more involved with recruiting and engaging people in the Earth Day Challenge. If you are interested in learning more please reach out to
