How do I create a team?

If you want to save CO2 together with your friends, you can set up a team together with other participants or join an existing one. Note that you must have at least 3 people on your team, otherwise you won't appear on the leaderboard.

Simply go to the “Community” tab in the app. There, you can create your own team or join one of the existing teams. From the official start of the Klimathon, you can then collect climate points for your team together.

How do I calculate my CO₂-Footprint?

In the next step, you can have your personal CO₂ footprint calculated. You can also do this before the Klimathon starts.

You can find the CO2 calculator in the “My footprint” app area and click on “Edit” (top right) to enter detailed information here. The CO2 calculator was developed together with the Fraunhofer Institute and is scientifically based. Answering the questions is voluntary. If you can't or don't want to answer a question, a German average is automatically assumed. However, the result is of course more accurate if you answer the questions individually and truthfully.

Complete challenges

From the official start of the Klimathon, there are 4-6 new challenges from professional or private life to choose from every week, which you can take on. Choose the tasks that are right for you and collect points. Each week, new challenges are added that match the respective topic. You can also take on multiple challenges at the same time. If you have successfully completed a weekly task, mark it at the end of the week by clicking on the green field “Yes” for “Completed.” Please be honest, because that is the only way to make it a fair competition.

Based on your individual information, the climate points currently achieved for your team are automatically calculated, and the average value is calculated. So it doesn't matter how many members your team has, what counts is the commitment of each individual. You can see how your team is doing compared to the others in the community section of the app on the leaderboard.

How do I get rewards?

You can redeem your collected climate points within the app with selected partners for discounts or vouchers. The offer ranges from sustainable laundry detergent to a fashion leasing service and vegan food - there is sure to be something you like.

The end of the climactic

You can join the Klimathon at any time, because it is never too late to start with the CO₂-Start saving. At the end of the six weeks, it will be clear which team was the most committed and how much CO₂ We were all able to save money together as a community.
