We have developed a methodology and proposed a new three-stage method for calculating the C-CO₂ balance when growing forests and using wood. The service life of buildings made of wood fluctuates slightly, averaging about 50 years, the former timber will rot and turn back into CO₂. Part of the wood is used to make paper, cardboard, plywood, and furniture. However, these materials and products have a short life span. Paper and cardboard are consumed. Furniture usually lasts no more than 25 years.

The initial large carbon sink with industrial wood leads to a temporary (up to 150 years) removal of CO₂ from the atmosphere. The long-term cycle of C-CO₂ in the system atmosphere - green plants - industrial wood - man-made buildings - dust- the atmosphere ends only with a small positive balance. It is known that only a small part – 0.8-1.0% of the organic matter synthesized by plants enters the large geological cycle. There is a highly effective way of using forest plantations to regulate the content of carbon dioxide in the atmosphere. This path is the use of a part of the wood for energy production and the replacement of fossil hydrocarbons. Indeed, when wood is used for energy, biomass carbon burns out and also enters the atmosphere in the form of CO₂. In this case, carbon dioxide does not replenish the pollutant pool. C-CO₂ simply recirculates. It is important to take into account that the transportation of biofuel from wood over long distances reduces its energy efficiency and increases C-CO₂ emissions into the atmosphere.
