I'm not sure what you question is getting at, but yes, the carbon will eventually be released from any wood. If wood-as-carbon-storage was going to be actively applied towards climate change, then it would be important to control the rate of released, by, for example, using the wood in buildings, burying it, or submerging it in water, so that it wouldn't decompose from fungus or termites.
