Climate Coin Münster
Climate Coin Japan
Climate Heart Darmstadt
Climate-Coin Dusseldorf
Climate coins are collected for CO2 savings and participation in social and environmentally friendly activities. The advantage of having your own climate currency is that you can determine where it can be exchanged – on the digital marketplace or locally in your city at retailers, in restaurants or perhaps also at sports and cultural facilities. In this way, regional companies can find an attractive marketing channel for their healthy, sustainable products and services.
One platform - so many opportunities
The Changers City app makes climate protection fun. Planting trees, collecting and redeeming climate coins, CO2 competitions and exchanges in your own community – gamification ensures long-term success.

Changers was recognized as an EUPD TOP BRAND in the area of workplace health promotion and by the Solarimpulse Foundation for efficient climate protection.
