SOS-UK is a charity created by the student movement in 2019 in response to the climate emergency and ecological crisis. It exists to support students to be the change that society urgently needs to get us out of the climate emergency and ecological crisis, and to deliver climate justice. All the work delivered has been instigated, led, or supported by students, enabled and mentored by the core staff team at SOS-UK; these range from energy saving in student homes, campaigns to radically reform how universities invest their money, to working with university tenant farmers to sequester carbon. Making sustainability more inclusive is a key aspect of SOS-UK's work, having recently launched its own climate justice and inclusion directorate.
