Payment system using taler.net . No fees (except a tiny fee to avoid attacks on the system, and another fee in favor of the salesman of a local store, see below), but in a disagreement/dispute between two prices, the difference goes to the United Nations to help the environment. This difference creates a Carbon credit (in fact Certified Emission Reductions, by the United Nations), which is split in half to buyer and seller.

This creates a sink of money (just like taxes), which attributes value to a digital coin (ec0.in , with symbol ϕ). The ec0.in is produced by aidpla.net (which acts as a kind of central bank) and it can be used in payments where Carbon credits are produced. To preserve privacy, the Carbon credit is represented by a spent digital coin (using Taler), through aidpla.net.

The sale of ec0.in creates immediately a Carbon credit (in fact Certified Emission Reductions, by the United Nations), and it is done through the salesmen in local stores, who can (and should) charge an optional fee to the client, say 3% which also covers the costs of conversion from the local currency to ec0.in. The salesmen can also refuse to accept ec0.in for his products after a certain pre-determined (by them) limit is reached. The salesman can print a QR-code which is a certificate that says to the clients that this salesman has a good justification for not accepting ec0.in temporarily, until he gets to sell all (or most of) his ec0.in.

aidpla.net charges 3% of the Carbon Credit, and a tiny fee to avoid attacks on the system. That is, aidpla.net only wins when there is a Carbon Credit produced otherwise the payment system is essentially free (except for the tiny fee to avoid attacks on the system). Note that aidpla.net itself is non-profit, with all profits either reinvested in aidpla.net or buying Carbon credits from the United Nations.
