The WWF issued tokens on Polygon (MATIC) as it consumes little energy. According to the WWF, “Each transaction has the same carbon emissions as a glass of tap water.”
Despite the organization’s choice to employ a long-term blockchain, the revelation was met with swift criticism.
Catherine Flick, a professor at De Montfort University, points out that Polygon is an Ethereum second-layer protocol. This is despite the fact that it consumes very little energy. She added that Polygon potentially helps with the energy-intensive process of crypto mining.
