…Sweden, like Canada, sits atop vast boreal forests — part of the same great green belt circling the Northern Hemisphere. These forests act as planetary lungs, storing more carbon than even the Amazon. But the Swedish government’s latest forestry inquiry, En robust skogspolitik för aktivt skogsbruk, is heading in a troubling direction: grow more trees, cut them faster, and burn or export more biomass in the name of “green energy.” It sounds like a climate solution. But here’s the problem: forests are not factories. Most of the carbon in a boreal forest isn’t stored in the trees at all. It’s locked underground — in roots, fungi, humus, and delicate microbial networks built up over thousands of years. When forestry is intensified — shorter harvest cycles, heavier machines, wider clear-cuts — that underground bank of carbon is steadily drained. The trees grow back, yes, but the soil can take centuries to recover, if it recovers at all.
