No I don't. But if wood lasted more than a couple of hundred years on average, then we would be neck-deep in old lumber. We're constantly cutting down trees, and yet the amount of wood in the lived environment isn't increasing noticeably.

Conclusion: all that old wood is either buried, or it's busy turning into CO2.

So I'm not impressed by claims of "carbon offsetting". On the contrary, I take such claims as evidence that the organisation in question is part of the problem.

Incidentally, how are you supposed to recycle chipboard? Like, for example a chipboard kitchen counter? For several decades, I had in my home a pair of oak side tables, that were made by my grandfather from the remains of a large oak dining table. You can't do that nowadays with chipboard.
