Carbon dioxide (CO<sub>2</sub>) is the main greenhouse gas released into the Earth’s atmosphere by human activities. The concentration of CO<sub>2</sub> in the atmosphere depends on the balance of natural sources and sinks, which are being perturbed by anthropogenic forcing due to fossil fuel burning, uncontrolled urban development, deforestation and other land use changes. An improvement in our understanding of processes responsible for absorption of CO<sub>2</sub> is urgently needed both for a reliable estimate of future CO<sub>2</sub> levels, and for the enforcement of effective international agreements for its containment.

The steadily increasing global carbon dioxide concentra­tion is further recognized through the decreasing trend of 13C/12C isotopic ratio in the annual rings of twentieth-cen­tury trees. The decrease is averaged to about 0.012 per mil per year which is attributed not only as due to anthropogen­ic fossil-fuel burning but also to the man’s impact on the land pattern.

Forestry's long production period entails compound interest, often making investments unprofitable. Several plausible but dubious arguments purport to excuse forestry from bearing compound interest: the existence of externalities, the invalidity of social discounting, the ability of previous revenues to bear replanting costs. The so-called "allowable cut effect" permits comparison of improvement expenditures with immediate yield. In a somewhat similar way, planting forests to absorb carbon dioxide permits almost-immediate burning of fossil fuel, a benefit offering simple interest on the planting costs. Such carbon-fixing plantations appear to be economic even when it is uneconomic to plant for fuelwood production. In one case study, the unit cost of growing wood for burning was £356 per tonne coal equivalent, while the cost of carbon fixing was only £76 per tonne of coal burned. The economic acceptability of such planting is not, however, established: particularly, fossil fuel burning may have other malign effects.
