Like many other alumni, we were proud to see Princeton again ranked No. 1 among American universities by U.S. News & World Report (On the Campus, Oct. 26). We wish that Princeton would have been ranked higher than 102nd among American colleges and universities that “prioritize environmental protection” by Sierra Magazine in its October 2016 issue. Admittedly the criteria used by the Sierra Club to establish its rankings could be at odds with other worthy institutional priorities, but it still would be gratifying to see our university ranked higher than 102nd among the “colleges working hardest to protect the planet in 2016.” Ultimately, it would be wonderful for Princeton to claim the No. 1 spot in both these college rankings.
