Savings: You save on annual car costs, because the price of biogas is lower and more stable than normal fuel.
Remember this: You may not live near a petrol station that sells biogas, because right now they are concentrated in southern and southeast Finland. They are quite uncommon in other parts of the country.
Reducing your carbon footprint: Driving a biogas car instead of a combustion engine car reduces your carbon footprint by 17.5% per year. If a million Finns did this, it would save the equivalent of 175,000 carbon footprints per year.
