No, trees grow, thrive, die, and then decay releasing the CO2 they'd absorbed in life as well as nutrients used by other life. You have to bury the lumber from a forest far from oxygen to get it to remove CO2 permanently. Also, forests only counter ~1 watt of gasoline combustion per square meter or so. That's only enough to sustain a pre-industrial standard of living as it did, in fact, do Back In The Day.
