Who said this is even tracked, let alone enforced? Drawing the conclusion that it's enforced seems like a bit of a leap.

That said, if my boss said that to me it would probably sit poorly with me in the moment purely because I just want to focus on my job and GTFO, I don't particularly want to pine for outside when I'm stuck anyways. It's corny and not particularly inspiring, but nothing wrong with it on its face. If somebody was clocking such things that's a huge "find another corporate wage slave camp to sink your labor into" flag.

I mean, corporate goals aren't always tracked or enforced. Officially stated corporate goals and values are used to help set priorities and culture, and including a goal of appreciating the environment the office is located in can be referenced in political pushes to further improve the workplace, such as encouraging (paid) early release on especially nice days, or setting up workplace picnics or even a workplace volunteer day. Or it can simply be a half-jokingly stated goal to take a moment to breath and appreciate the world around you that's entirely untrackable and unenforceable
