Successful climate protection for any size
Due to size and administrative structure, municipalities, cities and counties have different challenges in the field of climate protection. With the Klimathon, 2zero offers a solution for all individual requirements
For municipalities
Municipalities often have limited resources and are looking for an affordable and easy-to-implement solution. With our basic packages, you can offer your citizens a climate protection platform in a few steps
For cities
Cities are mainly looking for scalable solutions for climate protection. With 2zero, you can actively involve your citizens in climate protection and jointly develop innovative solutions for a sustainable future.
For counties
Counties, on the other hand, often have to coordinate several municipalities and cities. With our city bets, you can start a jointly coordinated action and uniquely inspire your citizens for climate protection.
