Funny - now you greens don't support harvesting of timber in BC as well. BC's forests (that are harvested) are fully regenerated with younger trees, that take up as much or more carbon than the mature and over-mature forests they replace (certainly more than the dead pine stands that were harvested in the Interior due to MPB). 

Over-mature stands (which are commonly harvested) are net carbon emitters due to decay (they lose wood volume).  In nature, these stands would burn, blow down, and/or just fall apart due to decay, and emit their carbon until a new forest regenerates and starts sequestering carbon again. Carbon is captured in lumber (for quite a while anyhow) - so the logging industry is aiding in capturing carbon, not releasing it.  The plantations are effective carbon sinks. I suggest that you maybe go take some forestry courses. First oil, then timber, what next? Minerals, grains, cattle? 

And by the way, Notley's correct - this is Canada's coastline, not BC's.
