For me it's a mental health and productivity benefit. You get longer down time and when you get back to work you have to endure only half a day to get back into work mode. On fridays you wrap up work and leave early so you're more focus on completion and you're less stressed. I didn't even consider the environmental aspect, a lot of workplaces already have work from home fridays, maybe having the half-days work from home makes better sense?
