This article talks specifically about energy usage, not consumption of products. Work from home likely wouldn't have an impact in consumed goods.
I'm a WFH employee, and my company has no plans to change it. I'm all for WFH. I brought up the issue of 100 companies producing 70% of greenhouse gases because to me this article lines up with the idea of us reducing our individual carbon footprint, which we've found out in the last few years was just a coordinated effort by the fossil fuel industry to deflect their responsibility to us.
All of these efforts are good. WFH is good, renewable energies are good, EVs are debatable (depending on where you stand on how the rare materials needed for the batteries are sourced) but overall better than gas and diesel. But at the end of the day, if your tub is overflowing you need to turn off the tap first before you pick up the mop.
