A brief description of the carbon sinks, including vendor, project source, verification program and contract timeframes (as applicable):

N/A

Adjusted net GHG emissions

Adjusted net Scope 1 and Scope 2 GHG emissions:

	Performance year	Baseline year
Adjusted net GHG emissions	92.85 Metric tons of CO2 equivalent	96.74 Metric tons of CO2 equivalent

Performance and baseline periods

Start and end dates of the performance year and baseline year (or three-year periods):

	Performance year	Baseline year
Start date	July 1, 2019	July 1, 2018
End date	June 30, 2020	June 30, 2019

A brief description of when and why the GHG emissions baseline was adopted:

The baseline was adopted as part of the baselining exercise for targets related to the University of Sydney Sustainability Strategy 2020. 2018/2019 was the most recent year without significant ecological and external factors to affect figures - a normal year.

Part 1. Reduction in GHG emissions per person

Weighted campus users

Figures needed to determine “Weighted Campus Users”:

	Performance year	Baseline year
Number of students resident on-site	2,051	1,180
Number of employees resident on-site	10	10
Number of other individuals resident on-site	13	13
Total full-time equivalent student enrollment	54,904.16	52,246.30
Full-time equivalent of employees	6,970.13	4,985.20
Full-time equivalent of students enrolled exclusively in distance education	0	0
Weighted Campus Users	46,933.97	43,234.13

Metrics used in scoring for Part 1

Adjusted net Scope 1 and 2 GHG emissions per weighted campus user:

	Performance year	Baseline year
Adjusted net Scope 1 and 2 GHG emissions per weighted campus user	0 Metric tons of CO2 equivalent	0 Metric tons of CO2 equivalent

Percentage reduction in adjusted net Scope 1 and Scope 2 GHG emissions per weighted campus user from baseline:

11.59

Part 2. GHG emissions per unit of floor area

Performance year floor area

Gross floor area of building space, performance year:

853,684 Gross square meters

Floor area of energy intensive building space, performance year:

	Floor area
Laboratory space	8,134.12 Square meters
Healthcare space	0 Square meters
Other energy intensive space	0 Square meters

EUI-adjusted floor area, performance year:

869,951.87 Gross square meters

Metric used in scoring for Part 2

Adjusted net Scope 1 and 2 GHG emissions per unit of EUI-adjusted floor area, performance year:

0 MtCO2e per square meter

A brief description of the institution’s GHG emissions reduction initiatives:

LED lighting upgrades (Carparks and a student 24/7 space in Carslaw Building)
Building Tuning / BMS optimisation project across buildings on the Camperdown/Darlington Campus
Building retro-commissioning (School of Information Technology Building and and New Law Building )
The University Sustainability Framework for Buildings including required design standards (which will be replaced by Green Star framework from 2021).
Additional on-site generation added on our Camperdown/Darlington campus with rooftop solar on 3 new buildings being commissioned - Susan Wakil, Chau Chak Wing Museum and Engineering and Technology Precinct bringing the total to 23 buildings with rooftop solar equalling 1.1MW generation.
Communication room are in switch-off mode during non-peak times and in buildings not used due to COVID restrictions are put into weekend mode with lights, A/C and monitoring powered down to very minimal use.
Christmas and public holiday closedown and switch off. Buildings are powered down or off during the three weeks of the university Christmas and New Year holidays. This results in the only buildings with lights on are being used to promote campus safety (light reflects on to public walkways and park areas) but AC etc. is powered down.
During the COVID restrictions period, the University powered down large parts of the Camperdown/Darling area and chose to prioritise student 24/7 areas in terms of electricity use. Before staff left to start working from home, they were reminded to power down any equipment not going home with them in a bid to reduce emissions.

Data source(s) and notes about the submission:

WCU for performance year differ from the WCU as per PRE5. Our performance years are on the financial year (1 July to 30 June). This is due to our required government reporting on emissions, energy use, waste and water (NGERS). The number of people provided in PRE5 is based on our census date of Semester 1 - 25 March of that year.

Figures in Part 1 differ from the Inventory displayed in OP1. The inventory provided in OP1 is the University's NGERS (National Greenhouse and Energy Reporting) which contains information linked to the University's extended boundary. For STARS reporting, our boundary was reduced to properties where the University has direct operational control i.e. omitting leased spaces and residential colleges. This accounts for space where the Sustainability Strategy 2020 has remit to make changes.
