Audi e-fuels are fuels made from renewable energies, water and CO2
Audi e-fuels:
• No fossil sources
• No biomass
• No competition with food production
• Use of CO2 as raw material

How do German customers use Audi e-gas?
► amount of fuel is registered via his Audi e-gas card
► Monthly account statement of amounts of e-gas purchased and reduction in CO2 emissions
► opt for a pre-paid contract for Audi e-gas
► Fill up on more than 600 German CNG stations
► Easy payment with e-gas credit card
► Monthly debiting of fuel price and e-gas climate fee
► Monthly reporting of saved CO2 by using e-gas
