Sounds a little futuristic. Although given the speed of modern scientific and technological progress, I would not be surprised if we see such technological solutions soon.
It would be good to see such a decision from project Greencoin. By the way, you can imagine that thanks to this innovation, the public would receive real data on harmful emissions into the atmosphere. Since I think that the real numbers hide from people. And here everything is transparent and accessible. It remains unchanged in the blockchain. That's what I understand help in the struggle for the environment!
