I’ve received this certificate and what a good feeling it gives.
I have no idea if a tree has actually been grown on not. Maybe the bank only paid some money to some people to plant trees and thereby issued the certificate. If they do actually plant a tree for each customer, they would end up creating a forest large enough to driven through. If the bank was so concerned about saving paper, they should stop paper statements for all customers anyways.
However, this initiative does make a customer feel nice. It certainly motivates people to use online facilities and save paper. If that’s what it takes to move people towards online options, then so be it.
For me, it’s left me worried. Who’s going to water the plant till it becomes a strong bountiful tree?
