Take part in the Lüneburg Klimathon!

Declaration of consent

The "Gebag Klimathon" app from the service provider 2zero gives you the opportunity to take part in the Klimathon. You can determine your personal _{CO2 footprint} and reduce it using various challenges. When determining your_{carbon footprint} and participating in the challenges, you will be asked to provide various details about your habits and behaviors, and personal data will also be processed. For this purpose, we therefore require the following declaration of consent under data protection law:

By downloading the app and participating in the challenges, I agree that the data collected in the course of using the app may be processed for the aforementioned purpose. Insofar as the information collected also contains references to sensitive data, such as information about my health, my consent also refers to this. My consent is voluntary and can be revoked at any time (e.g. by deleting my account). Failure to give my consent will have no further effect, but will only result in me not being able to use the app and participate in the challenges. For more information on the type and scope of data processing within the framework of the app and on my rights, I can refer to the data protection notices.

How do I create a team?

If you want to save CO2 together with your friends, you can create a team together with other participants or join an existing one. Note that you must have at least 3 people in your team, otherwise you will not 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 Climate Marathon, you can then collect climate points for your team together.

How do I calculate my_{carbon footprint}?

In the next step, you can calculate your personal CO₂ footprint. You can also do this before the start of the Climate Marathon.

You can find the CO2 calculator in the app section "My footprint" and enter detailed information here by clicking on "Edit" (top right). The CO2 calculator was developed together with the Fraunhofer Institute and is scientifically based. Answering the questions is voluntary. If you cannot or do not want to answer a question, a German mean value is automatically assumed. However, the result is more accurate if you answer the questions individually and truthfully.

Complete challenges

From the official start of the Klimathon, there will be 4-6 new challenges from your professional or private everyday life for you to choose from each week. Choose the tasks that suit you best and collect points. Every week, new challenges are added that fit the respective topic. You can also take on several 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 "Yes" field for "Done". Please be honest, because this is the only way to make it a fair competition.

On the basis of your individual data, the currently achieved climate points for your team are automatically calculated, and the average value is determined. So it doesn't matter how many members your team has, what counts is the effort of each individual. You can see how your team is doing compared to the others in the leaderboard in the community area of the app.

How do I get rewards?

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

End of the Climate Marathon

You can join the Klimathon at any time, because it's never too late to start_{saving CO2}. At the end of the six weeks, we will see which team was the most committed and how much_CO2 we were able to save together as a community.
