Good forestry is also good for the climate
As a way of thinking, sustainability is well suited to forestry, since forests have traditionally been seen as an asset that will benefit several generations. From a forest owner’s point of view, the most essential factor in climate change mitigation is ensuring that forests remain viable. “Making sure that forests are in a fit state to grow is key. When trees fall, the carbon that has been stored in them is released,” says Jyrki Kangas, Professor of Forest Bioeconomy at the University of Eastern Finland. The trees and soil in forests absorb carbon dioxide and act as carbon reservoirs. In principle, extending forest turnover times improves the carbon balance, but trees cannot be left to grow infinitely. The optimal time for harvesting, considering both forest productivity and the climate, is before tree growth begins to slow down and trees become more susceptible to damage. From the point of view of carbon binding, it is essential that forests produce wood as efficiently as possible. The faster a forest grows after a regeneration felling, the faster it will begin to store carbon.
