The majority of advertising on environmental initiatives ("hey go out there and recycle" and that kind of crap) is funded by polluters to shift the conversation from a manufacturer problem to a consumer problem. You need to ask "who is advertising" and "who is the market."

So let's say Zoom wanted to run an initiative like this… the market wouldn't be workers, it's be the bosses. So already you're talking about a tiny sliver of the population. No billboards or tv spends, that's for the mass market.

Okay, now that you've identified the target audience, what do they respond to? "This way of working that most of you hate, it's happy days and sunshine?" No, they respond to money. The campaign that would resonate with bosses is "your office lease costs too much money." Environmental concerns wouldn't even measure up.

Having said all this, I suppose one could make the case that remote-work-apps could advertise to "shift the conversation" amongst workers to demand remote-work for the sake of the environment, but I personally don't think anyone in America at least believes in this kind of grass-roots influence in business, that's too socialist.
