How the DGT's position has evolved
Current position
Agricultural tractors authorized to travel on public roads may use subsidized diesel if they are used in agriculture, livestock, or forestry. Forestry activities include marking, felling, pruning, clearing, and herbicide treatments for fire prevention. Industrial wood processing and wholesale trade are excluded from forestry.
The DGT's position remains stable regarding the definition of forestry, focusing on the care and exploitation of forests. Throughout the rulings, it has been specified that clearing and fire prevention tasks qualify as forestry. There have been no fundamental changes, but rather a confirmation of the application of the benefit to specific agricultural machinery.
Turning points
-
It is established that clearing forest roads for fire prevention is considered a forestry treatment.
-
It is clarified that the use of subsidized diesel in special vehicles authorized to travel depends strictly on the machinery being used in forestry.
