If you cover an area with trees that is today not covered with trees, that area will absorb CO2 from the atomsphere. Even if the trees die or are cut down, as long as new ones are allowed to grow, that area will absorb roughly constant amount of CO2. Now, if we can harvest some trees regularly, and use them to replace plastics or fossil fuels, then that's a win for the environment even if those harvested trees end up releasing their CO2 back to the atmosphere, because we didn't introduce any _more_ CO2, we just recycled what we already have.
