Whether it's the design cycle, production planning, marketing, or the financial consequences, I don't see any of the major American automakers being prepared to go electric only in ten years. Mind you maybe they'll surprise me. I'm just going by casual observation of the news and a couple of random conversations with insiders. Of course they're all making a new EV or two, hedging their bets in case they're forced in that direction, but even in Europe where the regulators are generally more serious about such things the automakers managed to get their EV mandate scrapped. What's more the plans are mostly just for passenger cars which leaves out quite a lot.
Net zero is absolutely possible, the technology exists, yes — after all it doesn't take much fancy technology to not burn fossil fuels and when it comes to transportation it's not hard to imagine reinventing passenger rail, rebuilding cities around public transport, living with a tiny fraction of the air travel we have today, investing heavily in sustainable agriculture, and so on. But it's a much bigger change than seems to be commonly appreciated even among people who think it ought to be done and I don't think the previous government of which Guilbeault was a part came anywhere near presenting a convincing case that they were on course to do it.
