For me this is a major factor in choosing an employer so I followed your link ([2]) but did not see anything in your principles that refers to working sustainably or work-life balance, etc.
The engineering principles take our overall organization values and lay out engineering-specific takes on them. I haven't seen the organization values posted publicly, but one of the top line values is "Work responsibly and sustainably" and I can say firsthand that this is something we talk about in management meetings.
