      I wouldn’t take it too strongly yet.

      Actually fueling a car is only something like 60 - 80% of the total carbon cost. Rest is manufacturing and disposal. Evs hold considerable costs (carbon, waste, human suffering) in terms of manufacturing and disposal, and only really pay off if their power is created in sustainable ways - otherwise you’re just pushing the problems out of sight.

        China’s energy grid is about 80% fossil fuels. Assuming their energy mixture remains unchanged (a bad assumption as their coal usage is on the decline) it would take about 65,000 miles for an EV’s carbon output to break even with an equivalent ICE vehicle.

        The waste and suffering involved in carbon intensive fuels is ongoing instead of being single event. One benefit of renewable tech is the recyclability of it’s components. Once we’re made the battery it can be recycled and died not require ongoing extractive mining forever.

        EVs have a place in a just future and can do some good at this time. Alternatives to cars are still a far more important and uncomplicated solution to our climate problems

          To start with I fully agree with your last paragraph- no arguement here.

          You’re right on recyclability, the problem is that they aren’t because the infrastructure isn’t in place or profitable. There is also the fact the earth doesn’t actually contain enough of the rare earth minerals to give everyone an EV (This is off memory, cant place the source).

          Yes, if you are only considering the individual’s carbon cost and power is generated via 100% renewable means.

          Something like 80% of China power is fossil fuels. Admittedly large scale power generation is more fuel efficient, and I don’t have the full numbers of carbon cost of manufacturing, but its important to keep in mind that carbon costs didn’t just disappear overnight.

          Another consideration is that Evs still drove car centric culture. If each EV saved 50% of a vehicles lifetime carbon, but it doubled the time for mass transport to be more widely adopted, lengthened the time for cities to prioritize other means of transport and city design, and means we as a society made 50% more vehicles did we actually save anything?
