Metsähallitus compared the emissions and consumption of biogas and diesel cars in Lapland - a clear difference
Metsätalous Oy compared the emissions of biogas trucks and diesel trucks when transporting timber in two test periods in summer conditions in September 2025 and in winter conditions in December 2025. In the tests carried out in Lapland, a biogas truck and a diesel truck drove the same route almost consecutively, both empty and loaded. The test periods lasted about three days at a time.
What is happening
Metsätalous Oy compared the emissions of biogas trucks and diesel trucks when transporting timber in two test periods in summer conditions in September 2025 and in winter conditions in December 2025.
In the tests carried out in Lapland, a biogas truck and a diesel truck drove the same route almost consecutively, both empty and loaded. The test periods lasted about three days at a time.
The interim results of the test periods show that the timber truck combination running on liquefied biogas produces clearly less greenhouse gas emissions in both summer and winter conditions.
Why this matters for transport
According to Metsähallitus, the biggest difference was found in the greenhouse gas emissions of the driving combinations.
Based on the intermediate results, the biogas truck also proved to be more energy efficient than the diesel truck in both test periods.
The energy consumption per ton-kilometer was 7.2 percent lower in the summer test period and 7.6 percent lower in the winter than the diesel control truck running on biogas.
What to watch next
According to Metsähallitus, the biggest difference was found in the greenhouse gas emissions of the driving combinations.
During the summer test period, the biogas truck's carbon dioxide emissions were 61-62 percent and measured per ton kilometer 63 percent lower than the diesel control truck.
Correspondingly, in the winter test, the emissions were 62–63 percent and 64 percent lower per tonne kilometer.
