Dear Michael 
Official information request for information on cloud data storage and 
carbon offsets 
I refer to your requests for information under the Official Information Act 1982 (the Act) 
dated 1 August 2019.  
Each of your requests, and the University’s response, is set out below. 
“Does Victoria University monitor and measure its use of cloud data services? If 
it does, please supply figures for the total size of VUW cloud data storage for the 
last five years, the particular cloud services which have been used, and any 
further relevant information that is available. If it doesn't, I would appreciate it 
if you give an estimate for current cloud use and what services are mainly 

The University’s Information Technology Services (ITS) have monitored some cloud data 
usage for approximately one year, but not across all suppliers. The University can provide 
the following estimate for the size of cloud data services for Microsoft.  
Microsoft Azure - Office365 Email Staff                            
Microsoft Azure - Office365 OneDrive Staff 
Microsoft Azure - Office365 Email Student 
Microsoft Azure - Office365 OneDrive Student 
The majority of the approximately 80TB of data stored by the University at Microsoft 
data centres is in carbon-neutral Microsoft data centres. We estimate the University’s 
data storage outside Microsoft to be around 40TB. The University uses the following fully 
certified cloud suppliers: Microsoft, Oracle, Panopto. 
The University is unable to provide further information without imposing a charge. In 
order to provide accurate figures for our other suppliers, our ITS team would need to 
undergo 22.5 hours of dedicated work. Using the Ombudsman’s charging guidelines, this 
would amount to a maximum charge will be $1,634.00. Any unused component of the 
maximum charge will be refunded to you. 

Before we proceed further with your request, please confirm your agreement to the 
charge and pay the full amount. The payment can be deposited in to the following account 
with reference ‘Michael Brown OIA request’: 
ANZ Bank New Zealand Limited  
Account number: 06-0606-0100241-oo  
Victoria University of Wellington 
Please note that if you pay the charge an email must be sent to [VUW request email]  
confirming the time and date on which the payment was made. We will send you the 
information within 40 working days of your payment. 
“Secondly, does VUW offset its carbon emissions resulting from cloud data 
storage? Or does it have any plans to offset these in future?” 

The bulk of data stored in the cloud for VUW is in Microsoft data centres – which have 
been 100% carbon neutral since 2012:
Our rough assessment of the carbon emissions impact of IT services and data storage 
estimated that the emissions from data storage (including the Microsoft storage 
mentioned above) would generate less than 2% of our total emissions. As stated above, 
the data stored in Microsoft data centres is already 100% carbon neutral. In relation to 
the remaining cloud storage, the University decided not to include this in the scope of our 
carbon footprint, and instead focus our efforts on areas where we can make a greater 
impact. As such, the University is not offsetting the emissions from off-site data storage, 
nor do we plan to do so. However, the University does intend to use carbon neutral data 
centres in the future wherever possible. 
You have the right to seek an investigation and review by the Ombudsman of this 
decision. Information about how to make a complaint is available at or freephone 0800 802 602. 
If you wish to discuss this decision with us, please feel free to contact me at 
[VUW request email]. 
Yours sincerely
