    I mean just looking at the amount of concrete in that picture, I get pessimistic. When will this particular site have dug itself out of the carbon “hole” created by its construction?

    As for trees: That is really, really hard to measure and even harder to know in advance. Some factors appear to be:

    • different tree species store different amounts of carbon
    • tree plantation or actual forest?
    • prior use of the site (e.g. meadows do store carbon too)
    • development over time (most trees need to grow a couple years before they start storing significant amounts of carbon)
    • failure of sites due to being planted in a bad way (e.g. a lot of Chinese Green Wall sites and quick-buck billion tree projects seem to be affected by this)
