SCOPE 3 JOURNEY
SBNMat Jane
Head of Environment and Building Services
Estates and Facilities Services

The University of Winchester• Founded in 1840
• 8,400 FTE students• 900 FTE staff• Rapidly growing institution• 77,500 m2 of estate (79% increase since2006)• 45% of the estate is residential with 1860
students in halls• 10% increase in estate in 2020/21 alone in
our new WDC building

Carbon Terminology• Scope 1 – Direct emissions• Scope 2 – Indirect emissions• Scope 3 – Other indirectemissions (more difficult tocalculate)• Location based reporting –based upon the gridemissions factor• Market based reporting –based on energy supply
factors

Type of Emissions

Scope 1
Direct emissions from ouractivities
Scope 2
Indirect emissions fromour electricity use
Scope 3
Other indirect emissions
associated with ouractivities and supply
chain
Emissions measured
Emissions not originallymeasured

Emissions sources

Fossil Fuels used to heat and operate
our buildings
Vehicle fuels from fleet consumption
Refrigerant Gas losses from coolingElectricity used for lighting, IT,
equipment, ventilation
Water consumed
Water discharged to sewer
Waste generated on campus & waste
generated from construction projects
Business travel
Air and rail travel booked for business
related work
Grey fleet usage
Staff/ student travel
Commuting to campus
Goods & services
All the things we purchasePurchased REGO certificates for gas and offset fleet emissions via carbon credits

Purchased 100% renewable power for all electricity supplies

Purchased carbon credits to offset emissions via the Carbon Coalition

Future purchase of carbon credits to offset remaining
S3 emissions via the Carbon Coalition

Carbon Management Plan• CMP in place since 2006/7 - Baseline 4200t• Significant reductions in CO2• £1.8m energy costs• 100% of electricity sourced from renewables
since 2008
• Onsite PV generation 2020/21 - 77mWh –around 2% of our total demand• 100% of gas sourced from renewablesources (biomethane) since September 2020

• We have spent over £2m on specific carbon
reduction projects since 2006
• £3.12m decarbonisation project underway

Total Energy Emissions Location BasedLarge Scale Decarbonisation Project
PSDS Funded project focused on degasificationand improving air quality£1bn fund - £3.12m grant to UoW
Installation of • 34 ASHP for 11 large buildings• 151 kWp Solar PV (300% increase)• BMS installation to 96 domestic boilers andoptimisation of existing systems• LED lighting upgrades• Guaranteed £68k energy cost savings and484t CO2

Fleet vehicles
Majority of remaining scope 1 from vehicle fuels
Fleet is 35 vehicles – now 16 are electric – 5 on order
Target – all fleet switched from ICE to EV by 2025

Priority for replacement is Diesel due to air quality

But…..Scope 3 Carbon
Scope 3 emissions dwarf our Scope 1and 2 energy emissions – 22k tonnes
Scope 3 is 95% of our carbon footprint
by current estimates (first pass)
To get to net-zero we will need arobust strategy to;• Avoid emissions• Remove emissions• Carbon Capture and Storage• Sequestration• Offset (the least preferable)

Scope 3 BreakdownEAUC Carbon Coalition Pilot
Consortium of UK and Ireland higherand further education institutions thathave joined together to deal with their
Scope 3 emissions.
• 386 tCO2e purchased for 2019-20• Carbon Neutral for Scopes 1&2plus Business Travel, Waste & Water.
• 50% UK Forest Carbon Code
• 50% Carbon Coalition Portfolio• Peer reviewed process for ensuring
offsets are verifiable, additional andof good quality

Future plans• Work on methodology for
improving scope 3 emission
data accuracy for reporting• Identify high spend areas to workwith suppliers to maximise impact• Ensure carbon is considered
at tendering stage for allpurchasing• Commuting impacts – more
students studying and living at
home locally could have asignificant impact
