Battery packs, car dashboards, your shopping bags as well as gasoline is made from oil, but only one of those is above 1% of world green house gas emissions. Creating graphene from gas instead of mining does seem cleaner, as methane can and probably will use green sources in the future. For NG -> graphene conversion, I don't see a problem, unless you're using it to smelt aluminum. OTOH, if batteries displace fossil fuel use, that seems like a huge positive, even with moderate amounts of aluminum smelting.
