Wood Preservation and Carbon Accounting: Why Treated Timber's Carbon Storage Is Often Overlooked

A new article from Wood Central highlights a significant gap in carbon accounting: the carbon stored in preserved wood is frequently ignored or undervalued. Wood preservation extends the life of timber products, keeping carbon locked away for decades longer than untreated wood. But current carbon accounting frameworks often fail to credit this extended storage, which could change how we value treated timber in climate strategies. The piece argues that if preservation is properly accounted for, it could boost the carbon credentials of wood construction and incentivize longer lasting timber use. For carbon markets and low carbon building policies, this blind spot matters. Ignoring preservation means underestimating the real climate benefit of treated wood products and potentially misallocating carbon credits. The article calls for updated methodologies that reflect the full lifecycle carbon impact of preserved timber.

Interesting piece. The carbon stored in preserved wood is a real blind spot in most lifecycle analyses. If we are serious about using timber for carbon storage, we need to count the full duration, not just the first few years.

This is the kind of detail that gets lost in high level carbon accounting. Preserved wood can last decades longer, so the carbon stays locked up. That should matter for credit methodologies.

Does the article cite any specific methodology that currently excludes preservation? I would like to see which standard or protocol they are calling out. Without that, it is hard to know how big the gap really is.

It is a niche point but a fair one. If you are building a carbon account for a timber building and the wood is treated, the storage period is longer. That should change the math on payback vs concrete.

This is exactly the kind of methodological gap that can distort carbon markets. If preservation extends storage but is not counted, then credits for timber storage are undervalued. Regulators should take a look.
