It takes 50 years to reabsorb deforestation emmissions! You often hear/read me drone on about the critical importance of avoidance carbon credits, particularly in the context of avoided deforestation. Steve Zwick elegantly summarised why those in the nature based solutions space insist on avoidance credits, citing this 2019 paper from Nature: One hectare of deforestation emits 355 tons of CO2 (all at once). One hectare of reforestation absorbs 6.7 tons of CO2 per year. In other words, it will take 50 years for newly planted trees to reabsorb the carbon released by every hectare deforested today. Reforestation is great, but stopping deforestation and degradation is critical. When you find yourself in a hole and want to get out: first, stop digging. https://lnkd.in/eyjqSEED

What the authors seem to be missing is that avoided deforestation does not equate to stable carbon storage in many regions. Even in the tropics, particularly with climate change, you will find significant challenges with natural disturbances as we look into the future. Every forester knows you have to examine forest structure continuously in land use planning and we have the modelling tools to do that. However, these decision support systems need to undertake regular reassessments of the landscape and all of its uses by human and non humans. Carbon accounting should be done as part of this process, not as a separate task

What if the harvested wood is converted to building materials, furniture and other wood products where the carbon continues to be stored? Had this been taken into account?

The analysis does not talk about the fact trees do not live forever. They take up carbon as they grow and give it back when they die. Ashes to ashes. Young trees are important in replacement for old trees. If you harvest and use the old trees you lock up that carbon for longer.
