I don't really like terms like "carbon-free" when most components, transports and many indirect pollution used by those infrastructure use oil-derived products It's like when I see the sign "0% pollution" on EVs, it's so far from the reality, it's the same order of magnitude of (direct and indirect) pollution than a fossil fuel vehicle, and a few order of magnitude larger than a bicycle (which is not exactly 0 too, it contains plastics, and a little bit of maintainance)
