First of all, as we work with RWA in renewables, we track our impact by the useful output - amount of energy used locally from our RWA.
In addition, as we focus on farmlands, we measure balance of the CO2 conservation by the amount of trees and food plants, produced within the farm.
Specifically to this proposal, desired impact is 1000 of european community members, tracked by the allocation addresses of our marketing utility tokens WeD, where we distinguish active accounts - who spend WeD for Impact, from passive accounts - airdrop hunters.
