This is feeling like déjà vu.  I think we got a very similar request at GNS a few months ago.
 
Nothing to add from CWU – we don’t measure shipping emissions.
 
Cheers,
Jocelyn

Hi Sarah
 
Our PM monitoring and compositional analysis has picked up contributions from shipping emissions at those monitoring sites near ports in
NZ. This includes Auckland, Redacted 9(2)(i) a Wellington, Nelson, 
 
 
 and 
Redacted 9(2)(i) 
 
 
 – whether that is relevant to Q1 depends on the
Redacted 9(2)(i) 
 
 
requester’s intent and the timeframe (2022 onwards?).
 
These datasets were generated as a result of client contracts with associated analysis and reporting (apart from the Nelson data which was
a FRST funded program 2009-2012).
 
Kind regards
 
Perry

Kia ora Sarah,
 
I think the answer is no, but I am sending this on to Perry Davy and Jocelyn Turnbull from the GNS BU as there may be some black carbon
data from the GNS BU that wasn’t considered previously as I believe that request pre-dated the merger. In addition, there may be some new
data from CarbonWatch-Urban, although I can’t think of anything directly shipping related. I’m also including Sally, as she has the best
overview of any work from NIWA’s old air quality team and is most likely to be aware of anything I’ve missed out on.
 
Jocelyn, Perry, Sally, do you know of anything?
 
Sara

Kia ora Sara
 
We’ve had the following OIA request which Melissa was handling, which was a refinement of an earlier request. I gather from Melissa’s
emails that we have nothing to respond to regards questions 1 & 2. Do you know if we would have anything with regards to question 3?
 
Given the answer was no to 1 & 2, I’d assume it would be the same for 3, but would appreciate your confirmation.
 
Thank you very much
Sarah
