Fully grown trees are carbon neutral. Yeah trees are made of carbon and when growing they pull carbon from the air and turn it into wood. Once fully grown that's it.

We should use more wood for construction, that way we clear more land for growing new trees with the wood essentially storing carbon in the structure of a building.

But the impact of that won't be much. We should do it because every little bit counts, but it would only be a minor part of a much larger solution.

We could also stop digging up oil from the ground and burning it. Novel idea I know.

Yup. That's the crux of the problem. We're pulling chemicals from the ground and burning it. Were do the gases from that go? Nowhere. They just stay in the atmosphere.
