This is the first NFT series form Block-CIMA. These tokens are backed by trees that are efficient in compensating for CO2 emissions. In the first series there are only 728 tokens. A total clearance of CO2 has been calculated in our lands with the result of 4076.8 tons per year. Therefore, every token allows to offset 5,6 tons per year (this is the average value of a Spanish's emission).
