The ethos behind Viridissima.es is to provide a "jumping off point" for low carbon blockchains. These currently include Flare (FLR), Songbird (SGB), Ripple (XRP) and XinFin (XDC) though I am sure as our project stack evolves, we will be onboarding other blockchains which fit into this category.
It is my firm belief that the rest of the planet should not be made to pay for our activities in the crypto space, as a result, I no longer involve myself with blockchains like Bitcoin or Ethereum. Now I hear you eth maxis shout "but ethereum is POS now" but here's the thing: the damage has already been done. Not only that but it is backed by a pretty shady group of organizations whose other activities are certainly not low carbon or carbon neutral.
Before onboarding other chains we will always do our due dilligence by trying to look below the surface.
