this is talking about reducing an individual’s carbon footprint… a drop in the bucket compared to big industry
Big industry exists to serve individuals consumption. Both of these things are one in the same, because everything that gets produced has to be consumed otherwise it gets put into a warehouse and the companies that are producing things go out of business.
With one person no longer driving to work every day big industry stops building oil and gas and whatever the heck else for them and starts instead building whatever they choose to spend their money on when they're stuck at home all day.
Probably internet games and food delivery. As long as those are less carbon intensive than the person driving to work every day, you get total net savings and it could be very significant.
