Abstract
This study sought optimal sustainable management regimes of uneven-aged Norway spruce-dominated stands with multiple objectives. The criteria were financial returns, CO
2 sequestration and diversity of tree size and species. At prevailing timber prices, harvest and transport costs, and interest rates, uneven-aged management for timber alone was most profitable with a 5-year cutting cycle. Lengthening the cutting cycle to 20 years decreased the net present value from timber by 10%, but raised the carbon storage by 21%, the tree species diversity by 32%, and the tree size diversity by 24%. Maximizing CO
2 sequestration induced an almost pure spruce stand. A compromise policy maximized CO
2 storage, while maintaining a rate of return on the capital of standing trees equal to the interest rate. A supply curve for CO
2 storage was derived, showing how much forest owners would be willing to sequester as a function of the price of CO
2. Maximizing the NPV from combined CO
2 storage and timber production showed complementarity of CO
2 storage and timber production for up to NOK 300 Mg
-1 of CO
2, and sustained, though lower, timber production at higher CO
2 prices.
