Growing trees to make them into timber, pulp, etc. takes CO2 out of the atmosphere. As long as you're not growing them to burn them, it's one of the most effective CO2 sequestration methods we have.

77% of tree usage in the US is for timber and pulpwood. Fast-growing species are planted and harvested over a 10-20 year cycle so that as each section is cut down and replanted, another section is maturing. It's both sustainable business and an effective CO2 sink.
