Step-by-Step Guide
How to calculate Ihren CO2-Fussabdruck step by step: 1. Wohnen: Heizenergieverbrauch enter (kWh Gas, Oel, Fernwaerme). Emissionsfaktoren: Erdgas ca. 0,20 kg CO2/kWh, Heizoel ca. 0,27 kg/kWh, Fernwaerme ca. 0,18 kg/kWh. Strom: je nach Mix ca. 0,38 kg CO2/kWh (Deutschland 2024). 2. Mobilitaet: Jaehrliche Fahrleistung (km) und Verbrauch angeben. Auto Benzin: ca. 2,37 kg CO2/Liter, Diesel: ca. 2,65 kg/Liter. Flugreisen: Kurzstrecke ca. 200 g CO2/km, Langstrecke ca. 300-400 g/km (inkl. RFI-Faktor). 3. Ernaehrung: Mischkost ca. 1,7 t CO2/year, vegetarisch ca. 1,2 t, vegan ca. 0,8 t. 4. Konsum: Kleidung, Elektronik, Dienstleistungen -- durchschnittlich ca. 2-3 t CO2/year. 5. Ergebnis compare: Deutscher average ca. 10,8 t CO2/year. Klimaziel: unter 2 t pro Person.
Calculation Example
Beispielperson: Gasheizung 15.000 kWh (3,0 t) + Strom 2.500 kWh (0,95 t) + Auto 12.000 km/7 l Benzin (1,99 t) + 1 Flugreise (0,8 t) + Ernaehrung Mischkost (1,7 t) + Konsum (2,5 t) = ca. 10,9 t CO2/year.
