The first comprised comparison of production directions. In the second stage reduction for particular production direction in dependence to production intensity were analysed the following variants of emission reduction were analysed: I. Ekstensification - emission reduction throughout decreasing of nitrogen inflow to the system; II. Modernisation - increasing of nitrogen productivity inflow to the system; III. Optimalisation - decreasing of nitrogen inflow to the system and increasing of productivity nitrogen inflowing to the system (this option does not lead for significant production growth). Analyse of emission reduction cost shows, that reduction by ekstensification leads to production decreases what can be recognising as emission reduction absolute cost. In the case of the second variant emission reduction the cost occurred only when cost of expenditure needed for obtaining growth of nitrogen utilisation on production would be higher than growth of the pure net production. Variant III represents cost of emission reduction under condition of production limitation.
