https://climate.mit.edu/ask-mit/how-many-new-trees-would-we-... says a new forest the size of New Mexico might offset the US's emissions. Or not. It depends. But first thing to do would be not to cut down the existing ones.

They say it would take a forest the size of New Mexico "to account for one year of American emissions" - given that trees both process CO2 during respiration and act as sinks when they grow, I can't tell if they'd be able to offset those emissions the next year as well or if we'd need a new forest.

Trees produce CO2 during respiration and intake it during photosynthesis. The carbon captured during photosynthesis will be offset to some degree by the tree's own need to consume glucose.
