Of course it's possible to make green HDMI cables. Use less plastic.And then they are marketing "greener" HDMI cables. Marketers are taking this "Green" buzzword waay to far.
You can be greener by getting cables from a place like Home Depot or a computer store. Home Depot has lots of cat6 and USB cables that don't even have packages, and the cables at computer places usually just have a plastic bag.You know what would be greener? Not putting a small wire in 3 lbs of plastic packaging.
Tritium is lighter than helium.Tritium injected cables FTW. Nearly as light as Helium and no trouble finding them in the dark!
