So mining the raw materials has zero impact to the net CO2 ? Because everything to keep a V8 on the road is all tallied into running a V8 for 100000 miles, calculating what batteries put off once created is great and all, but that's not a true measure. Also not to mention the batteries on a Prius are recycled as they used whole material vs plates material. Plating zinc with a tiny bit of cobalt for a lithium battery is what's happening now, when exactly are people gonna recycle for trace amounts of materials? Like we can't even get people on board with recycling bottles and cans that have a deposit on them here in VT never mind the rest of the country that largely does zero recycling.
