I have 52 planted trees since I joined (approximately 6,5 Trees per month). So I am way under the average but I would think as only payments with the Mastercard count for planting and spending 2400€ per month is nearly impossible with an average income (at least in my point of view) if you are not completely spending all the money you earn for consuming. (Which would also be not really good for carbon emissions). Also an influential fact is, if shared bank accounts, with for example your partner (wife,husband,…) are at bunq. The bank account I share with my wife is not, so the money we spent there is not going to plant trees for me.
