Doesn't say, but if the electricity used is from renewables then it's irrelevant, as it can potentially produce graphene at 5% of the current price

Found this re co2

Compared to commercial methods for carbon nanotube production that are being used right now, ours uses about 90% less energy and generates 90%-94% less carbon dioxide," Wyss said.

If they're making graphene and hydrogen then there can't be much left over can there?
