Speaking on the YLE investigative journalism show Pallo Hallussa, he says his Ministry is prepared to consider cutting or eliminating excise tax for farmers who produce crops suitable for biodiesel, such as rapeseed or oilseed.
Similar tax breaks have been granted in most other European Union countries.
Experts have speculated that the high taxes have prevented the wide-spread adoption of farming machines in Finland which can run on biodiesel.
The encouragement of biodiesel for machinery is in step with the Ministry's upcoming proposals on encouraging biofuel in general as an alternative to oil. The biofuel working group is expected to present its recommendations next week. Last autumn they were given the task of coming up with ways to increase the amount of biofuel used in traffic to five percent.
