This data may not consider reforestation. Yet, reforestation cannot replace the ecological systems of old-growth forests and their related social relations. Sweden is interesting. Despite reforestation, old growth forests are being destroyed at a high rate. Also, young trees absorb much less CO2.

‘Forests are not renewable’: the felling of Sweden’s ancient trees

Forests cover 70% of the country, but many argue the Swedish model of replacing old-growth forests with monoculture plantations is bad for biodiversity

But the picture is of course more complex than new trees versus old growth forests with regards CO2 absorption. While treelings cannot absorb so much CO2 yet, it appears as if middle-aged trees (50-140 years) absorb more CO2 than old trees (in which CO2 is already stored).
