Due to the gradually increasing energy usage there is a larger amount of raw-material need, which entails more and more burden on society. All countries are devoted to increase their energetic independence by taking advantage of their own domestic resources. Therefore, countries encourage the substitution of fossil energy with renewable ones, which results less environmental and polluting effects. Approximately 69% of the Hungarian territory is agricultural area, nevertheless, 236 thousand hectares have not been cultivated or completely desolated. These territories are not suitable for food-crop cultivation because the areas are mostly waterlogged or have much lower nutrition content; however, with appropriate selection of tree species, these areas can be populated with short-rotation energy plants. Dendromass can be considered as carbon-neutral energy resource only in the case if it substitutes a fossil fuel that provides much less favourable CO2 emission. Having examined the energy balance and discovered the possible correction steps, a new agricultural and also renewable energy strategy can be developed which facilitates climate protection. Though, there are no accurate data available in Hungary about the cultivation and utilization of short-rotation plants’ CO2 emission at the moment. In the Future further examinations are needed. The factors, which influence the carbon balance can be divided into 4 groups: production technology, circumstances and method of cultivation, applied machinery and energetic recovery.
