Your own annual CO₂ footprint can be estimated using the climate fund. The clear and interactive medium is particularly suitable for teaching purposes.

Three flights, a lot of exotic fruit and electricity from the conventional power plant – that does 13, 5 tons CO 2 – consumption per year. With the Klimakasse, interested parties can get a feeling for how high their CO 2 footprint is and how much in just a few minutes the areas of consumption, mobility, nutrition and energy contribute to this. I developed it for the Greenpeace group Wuppertal, where it will be used in the future at information stands.

The checkout includes a series of 3D-printed models with built-in NFC tag stickers, which represent different areas of life and consumption habits. A wind turbine stands for the use of green electricity, while a power plant stands for conventional energy. Anyone who has treated themselves to a two-week cruise scans the cruise ship and a large mobile phone symbolizes high spending on entertainment electronics.

Each participant selects the models that apply to him and pulls them over the built-in NFC scanner. The scanned inputs are recognized by the microcontroller, an ESP 8266, and are displayed on the screen with their ” Price “, ie the respective annual CO 2 emissions, listed, similar to a receipt. A piezo buzzer also provides the appropriate noises.
