Every time you see a wood building, it’s a storehouse of carbon from the forest. When you see steel or concrete, you’re seeing the emissions of carbon dioxide that had to go into the atmosphere for those structures to go up.

Chatting to one developer company, yes wood doesn’t have any thermal mass, but when you are heating (or cooling) the building, you don’t need to also heat (or cool) the physical ‘thermal mass’ structure either.
