The tree planting thing is embarrassing. That needs shot down and it can't be used by any corporate body as a green credential surely!
Why not? If a company can credibly plant enough trees to offset, say, a century of their facilities carbon impact - that seems pretty good to me.
Do you have a source that that is the requirement? It's not my understanding.
You cannot "offset carbon" by just planting trees.
You also need to wait until they grow, chop them down, and not burn them but burry them underground instead.

(1) building burns (2) building is torn down and wood rots (3) building eventually collapses and wood rots
i.e. if you don't bury it, it eventually returns into the carbon cycle
