Greeneum wants to make it easy to contribute to the future of green energy. Co-Founder Guille Wajner states that the company does this by focusing on elements that strengthen and secure their users' financial positions. Greeneum issues smart contracts called Green tokens, which are used as the medium of exchange and reward in the Greeneum community. Wajner says that the Green tokens can be used exclusively to buy items from their marketplace, contribute to sustainable solutions, or even purchase Greeneum Carbon Certificates, which would reduce your carbon footprint. The company's overall mission is to move toward a greener planet.
