University of Oxford Environmental Sustainability Report 2010/114Carbon reductionThe University increased its absolutebuildings-related emissions by 2.2% (from79,612tCO 2 in 2009/10 to 81,362tCO 2in 2010/11). However, emissions persquare metre floor space fell by 2.9%.The emissions increase was due to theGraph showing how much the Universityneeds to reduce its emissions by 2020:Tonnes of CO290,00080,00070,00060,00050,00040,00030,00020,00010,00041,28177, 93765,980Actual emissions frombuildings and owned vehiclesBusiness as usual 2020 projectionHEFCE 2020 targetPreferred CarbonManagement Scenario29,500m 2 expansion of the Universityestate (Earth Sciences building, SwindonBook Store and Oxford MolecularPathology Institute).

To meet our targets, we mustreduce emissions to 58,722tCO 2 by2015/16 and 44,152tCO 2 by 2020/21.The Carbon Management Strategyoutlines how the University can meet itstargets by using energy more efficiently,investing in energy saving equipment andenergy efficient buildings.Total (t)We produced our own electricity2,445.8530The Biochemistry building’s solar5971.72photovoltaic installation generated 93.815,700 kWh of electricity comparedto 3,500 kWh last year – an increaseof 63%. FAI Farms – tenants on theUniversity owned Wytham Estate –installed photovoltaics on the farm’sroofs to generate renewable electricity.We created an onlineEnergy ToolkitThe Energy Toolkit contains top tips forstaff and students on how to use energymore efficiently:www.ox.ac.uk/staff/news/energy_toolkit.htmlIn 2012 the University will finalise its carbonreduction plan and continue to reducecarbon as part of its 10:10 Campaign.600400
University of Oxford Environmental Sustainability Report 2010/115Water consumption20/211,000s m 3In 2010/11 the University consumed349,490m 3 water compared to347,364m 3 in 2009/10 – an increaseof 0.6%.We set a water reduction targetThe University set a water target toreduce water by 11% (38,210m 3 ) by2015 compared to 2009/10 levels(347,364m 3 ). This means the maximumamount of water that the University can6005004003002001000Total (t)2,445.85305971.7293.81consume in 2015 is 309,154m 3 . Whilethis is a challenging target, the University’swater consumption has been slowlydecreasing over the last decade.Graph showing University waterconsumption 2001-2011:We published a WaterManagement StrategyThe University published a WaterManagement Strategy which providesa road map for reducing waterconsumption in the University:www.admin.ox.ac.uk/estates/environment/waterWe installed rainwaterharvesting in our buildingsThe University installed rainwaterharvesting systems in four locations,to flush WCs:Biochemistry building has rainwatercapacity of 18m 3 and used 176m 3(1.9% of total building’s water use)Earth Sciences has rainwater capacityof 6m 3 – no water data availableOld Road Cancer Research Building hasrainwater capacity of 18m 3 and used366m 3 (2.6% of total water used)Oxford Molecular Pathology Institutehas rainwater capacity of 16m 3 –and used 100m 3 of waterHow much did we pay forour water?In 2010/11 the University’s total watercosts were £601,173 compared to£592,886 in 2009/10 – an increase of1.4%. The University pays over £1 per m 3water and a further £0.53 per m 3 to treatwaste water (a cubic metre is equivalentto 2,000 half litre bottles of mineralwater). The cost of water will continueto rise due to water scarcity, maintenanceand treatment, so we must use watermore efficiently.Case studyThe Clarendon Physics Laboratory cutwater consumption between 2006 and2011 by expanding their process coolingsystem. A water audit showed their waterconsumption reduced 23,600,000 litresper year over a 5 year period (42%).We’ll measure and report our carbon (CO 2 )emissions generated from water consumption,as required by HEFCE. In 2009/10 theUniversity generated 367 tonnes of ‘indirect’CO 2 from water consumption due to theabstraction, transportation and processingof water (water’s carbon footprint is 1.05kgCO 2 per m 3 ).In 2012 the University will implement itsWater Management Strategy and reducewater consumption:prioritise water efficiency in buildingsthat use lots of waterincrease rainwater recyclingfit low flow taps and showers andWC water saving devicescalibrate taps and showers for shorterrun timesfit smart meters on supplies to identify leaksrationalise the use of purified water andincrease the prevention of limescale build-up2000/012001/022002/032003/042004/052005/062006/072007/082008/092009/102011/12YEAR
