How so?

I mean you put it as a generic thing which means it's independent of other details, including a "way" so you suggest it's a significant difference clearly. This must be based on detailed data or research, right? Care to share that?

Because otherwise, I have a few questions:

• Is the whole supply chain included? Developer, Ops, Admin, Data Center, cabling, everything? Or just the legally mentioned admin on the page, respectively the lawyer?
• What if the page from home (and the whole home!) is running on hardware that gets electricity from fossil fuels + cooks with gas while the office and it's page all run on renewables?
• What if the page deployed from home is written extremely ineffective, so it uses multiple times more electricity?
• What if the office in question is the back office of a pet shop? Or a supermarket? Or a DIY superstore? They'd heat the place either way, so why not also deploy the website from there?

And don't get me wrong, I'm a staunch supporter of closing down offices as possible. But generalizations such as these help no one, and also just like the OP completely miss the point of talking about carbin emissions and climate impacts.
