Halftime at the climathon: Memmingen is already saving 13.1 tons of CO₂!
An exciting project is currently underway in Memmingen that promotes climate protection in an innovative way. The current climathon shows how you can reduce your CO₂ footprint through everyday decisions, because everyone can take part. Today, July 15, 2025, the competition is halfway through and the first successes paint a promising picture. The climathon, which was initiated by the city of Memmingen, has mobilized numerous participants over the last three weeks to take on challenges in the areas of housing, nutrition and leisure. According to information from Memmingen, an impressive 13.1 tons of CO₂ have already been saved. Memmingen reports.
The idea behind the climathon is to motivate the participants and introduce them to a sustainable way of life in a playful way. The “2zero” app supports this with daily challenges that do not require long lectures. Gamification elements such as collecting points and rankings ensure that the fun is not neglected. The app concept was developed as part of a research project and has already proven itself in over 90 municipalities and companies. It is clear: the aim here is to send a strong signal for sustainability that fits well into our times. Further information about the background, including the popularity of the app, can be found on the website 2zero.
Where is the journey going?
After the first three weeks, the climathon begins the next round. With the upcoming topics of mobility, consumption and digital life, exciting challenges lie ahead. Participants are welcome to join at any time and calculate their individual CO₂ footprint and actively fight against climate change by downloading the free app and registering. Similar climathon programs are currently running in other regions, for example in Schleswig-Holstein, which also contribute to saving CO₂ emissions and promoting a sustainable lifestyle.
Climate protection initiatives are more than just a trend - they are crucial to combating climate change that is being felt worldwide. Governments, companies, NGOs and each and every one of us act to reduce greenhouse gas emissions and promote sustainable development. The challenges that many cities and communities face are diverse and range from promoting renewable energies to improving energy efficiency. Climate change info highlights the most important measures that we can take together to continue to live on an earth worth living in in the future.
The climathon in Memmingen is a good example of how local action on a small scale can make a big difference. In order for the next three weeks to be as successful as the first, we need the commitment of all participants. After all, climate protection is a shared task! By joining forces, we can achieve a lot and shape low-emission everyday life to some extent ourselves.
