The forest production system is taken to mean the production system into which the material and resource flow and or even the workforce flow enter. During the production process the material power and or workforce flow is transformed into the final product processed timber soil preparation afforestation etc. . Operating and or design capacity is the control variable optimizing the operating mode of the forest production system. The quantities of emitted pollutants related to the work unit done by the production system represent the criterional function specifying the optimization of parameters of the mobile offroad system working in the forest sector. The conditions for the operating mode performance of the mobile off-road system working in the forest environment under which the minimum emitted pollutants related to the unit of done work are reached have been determined. The theoretical conclusions have been verified experimentally. Keywords forest technology SO2 NOx NCx optimizing minimization Production processes used in the implementation of silvicultural and logging operations in forestry bring about large amounts of gaseous and liquid emissions of extraneous substances. Many of them cause the pollution of atmosphere and or soil surface and ground water .
