1. Qualifiers

Register until 10th Aug 2022.


The qualifier round is a 25-minute online quiz. You can do this online right now, later, or as a student at your school. It works on your computer or smartphone.

From February, schools can register their qualifier events to allow all students to participate in sync. Upon verification, schools can also get printable versions of the sheets and conduct exams in paper form.

Each person can participate up to 3 times plus 1 per person they refer.

All participants will receive a certificate, and top participants a special honour.

Prepare with our quiz app available for Android and iPhone.

Quarter Finals

2. Quarter Finals

Jan-Aug 2022.


The best 10% of all qualifier attempts advance to the Quarter Finals. Quarter Finals follow the same quick-question format as Qualifiers.


3. Semi-Finals

Mar-Sep 2022.


Congratulations! You've demonstrated advanced knowledge on climate solutions. Now it's time to put this to good use and start solving some real problems.

In the Semi-Final, you choose one of three problem statements to respond to. To help you prepare, you are told the topics 10 days before the event, but the exact problem statement is only revealed at the start of the actual qualifier event.

Then you have 3 hours to research and write essay responses to questions related to the problem statement. ClimateScience will score each team's solution.

The Final

4. The Final

October 2022


Every finalist will be awarded a Bronze Medal, the top 20 and top 10 will be awarded a Silver and Gold Medal, respectively. The top teams split the prize pool of $15,000 (USD).

In the finals, you'll write a proposal about a major climate-related issue and be interviewed by our judges. As in 2021, we hope to conduct the winners ceremony at the United Nations' Climate Summit (COP) and give the top teams the opportunity to present their solutions on a world stage.

Register now!

Participate on your own or in a team of two, and compete against youths from around the world to find solutions to climate change. The top 10 teams will win a share of the $15,000 prize pool.

The CSO22 has three age brackets: under 16s, 17-19, and 20-25 years old. Regardless of age, participants compete in the same qualifiers and answer the same type of problem statements. However, we only compare participants within their age brackets. This means we score the three brackets independently and normalise scores within each. Semi-finalists, finalists, and winners are those with the highest normalised scores. This ensures fair comparison regardless of age.
Registration for qualifiers ends on August 10th, 2022
You can participate up to 3 times plus once for every referral you make.
Only 10% of participants will advance to the quarter finals and 10% of those to the semi finals, so preparation makes a major difference. You can take our courses or complete our quizzes in the app. Beyond that, read about whatever you are interested in and describe your solutions during the event!
Prize Money: - First place wins $5,000 - Second place wins $3,000 - Third place wins $2,000 - Participants ranked 4th through 7th win $1000 each and 8th through 10th take home $500. All figures in USD. Winners will also get a chance to speak at the Award Ceremony, hopefully to be conducted at COP27, just like in 2021.
Results for qualifiers and quarter finals are instant via our UI and via email. Semi finals results will arrive close to the finals date. Please do not send us emails asking when results will be announced.
Schools can choose to run qualifiers digitally or on paper. Paper participation will launch in late February 2022. Schools that participate digitally need one computer, laptop, or phone per student (students can use their own devices too) and one computer for the teacher leading the event. Teachers need to follow procedures for timing, ensure no cheating, and collect responses securely after the event ends.
