Many trees live for over 500 years (Redwoods, Cedars, Douglar Fir, Oaks, etc.). They can be part of the solution of keeping CO2 levels down while our energy system is de-carbonized. Go ahead and plant trees. They are great in many other ways also.

Trees tend to stop growing after about 150 years, so trees left standing longer than that will delay releasing the CO2 they've already captured, but will not continue to capture carbon. Indeed you probably want to cull trees before their growth rates start to decline around the 100 year mark to maximize your carbon capture rate.
