Lights off. During Earth Hour today from 8.30 PM to 9.30 PM, we will shut all non-essential lights of several of our buildings. Obviously, shutting the lights for an hour is not enough on its own, but it can be an important reminder. #WeAreHelsinkiUni #EarthHour #sustainability https://t.co/dppI0mzZcl
