The article reviews the ability of coniferous (common pine, siberian larch and siberian spruce) stands growing in 9 municipal districts of the Irkutsk region to absorb СО 2 technogenic emission of heat power plants. (EIGAF) index is suggested to characterize gas-absorbing (СО 2-absorbing) activity; the index reflects proportion between СО 2 technogenic emission and photosynthetic productivity (GPP) of coniferous tree stands. СО 2-absorbing capacity in 8 of the monitored districts has been shown

The index values EIGAF=0.01-0.97 demonstrate that СО 2 technogenic emission amounts to 1-97% of coniferous stands photosynthetic productivity in the areas under study. At the same time, the most industrially developed Angarsk district shows СО 2 photosynthetic absorption to be 8-12 times lower than technogenic СО 2 emission. Reasons of low gas-absorbing capacity of coniferous tree stands of this area are discussed.
