Just a side note:
Trees take in CO2 from the air. That atmospheric CO2 is stored inside the timber. When that timber is turned into a forest product (lumber, paper, etc.), a lot of atmospheric carbon is still locked into the product. If the timber/forest product is burned, no new atmospheric CO2 will be returned to the air. (The net effect is 0 at worst. Think of drawing a bucket of water from a pond and then pouring it back in). Oil and fossil fuels, however, have been stored underground for centuries. When these forms of carbon are burned, new CO2 is added into the atmosphere.
Conclusion - use more forest products. Timber functions as a natural CO2 container. The more trees we grow, harvest and replant to start the cycle over again the better. The only new carbon from fossil fuels needed is to generate the chemical reactions and mechanical operations required to create the wood product. Fortunately, many paper and lumber mills can take off some of the strain by combusting scrap wood for energy.
