Dear Ms Metcalfe,
OFFICIAL INFORMATION ACT 1982 (OIA) – REQUEST FOR INFORMATION - CHRISTCHURCH
INTERNATIONAL AIRPORT LIMITED (CIAL)
1.
We write further to our email of 8 August 2023 and our letter of 31 August 2023, in relation to your
email of 5 August 2023 (via the third party public platform fyi.org.nz) in which you requested the
following information pursuant to the OIA:
“I’m interested to understand how you calculate carbon emissions, and would like to look closely at
the numbers.
For the most recently published carbon emissions reporting period (of 12 months) please provide:
a) The detailed base data from which the calculations were made - not summarised, but
raw data. If you need to remove details like company names that’s fine.
b) The worked up calculations (summarised)
c) Details of the carbon reporting standards and methodology you have followed.
d) Details of any offsets you have applied, including full details of the scheme, how the
offsets are achieved, governance etc.
e) In the time since you have claimed that Christchurch Airport is “climate positive” or
similar, the total emissions (all scopes included) at the airport.”
(the
Request).
2.
CIAL calculate our carbon emissions, or rather our Greenhouse Gas (GHG) Inventory, using
independent expertise. The process is as follows:
•
After the reporting year is finished, we do a “call out” across the business, and into our supply
chain to report back and provide the data evidence for all the GHG activity items for the year.
CIAL compiles this information and sends it to a third party, Conversio, who specialise in
GHG accounting and airports. Conversio assesses the data for any gaps and helps CIAL with
any emissions factors that might not be provided for within MfE Guidelines, the ACERT or
CORSIA CERT frameworks.
•
Once the above step is complete, CIAL’s GHG inventory and data is then independently
audited by Ruby Canyon Environmental – who have ISO 14064:3:2019, GHG Protocol and
Airport Carbon Accreditation verification audit approvals. Ruby Canyon Environmental have
a best practice, two-step process within their organisation for the audit, in which one group
do the audit, and the other independently peer reviews that work.
•
Our GHG Inventory is then sent on to the Airport Carbon Accreditation programme, which is
the industry best practice for Airports. They have a team from WSP that also peer review the
GHG inventory - this is not an official additional independent audit though, just another step
where it gets checked.
3.
More specifically in relation to parts (a), (b) and (c) of your Request, CIAL publicly publishes its
independently audited GHG emissions on our website - please refer to the Conversio report titled
