Let's see...I had to pay for high-speed broadband (and government rules limit how much I can reclaim). This is consumer grade and there's no SLA, I simply cannot afford a "proper" connection.

I have to heat the home all day (more CO2).

I have to run all the PCs at home (I cannot reclaim those costs).

I still have my motor vehicle (so that fixed cost is still there).

IMHO working from home is a net environmental and fiscal cost.
