The University of Hull has over 18,000 students and 2,500 staff across its main and satellite campuses. It aims to reduce its carbon emissions by 34% by 2020 and 80% by 2050 relative to 1990 levels in line with UK climate targets. Installing automatic meter reading and flow reduction devices in student residence hall showers could save on water, energy, and emissions; and pay for themselves within a few years due to avoided costs under the UK's Carbon Reduction Commitment policy. The university holds energy saving competitions between residence halls to reduce consumption by 10%.
