Fire is a bit complex - some forest plant communities are adapted to frequent low-intensity fire. Keeping those fires happening is necessary for those forests to continue sequestering carbon.
Charred wood also decomposes at a much slower pace than fallen wood. Partial burns that produce charcoal rather than ash can lock carbon up for a long time.
But it’s negligible if we just release it back into the atmosphere. Or a forest fire occurs.
