From: Chris McCashin
Dear Ministry for the Environment,
I am writing to request information under the Official Information Act 1982.
It is noted that the Ministry for the Environment has publicly stated there is no evidence to suggest that geoengineering activities are currently taking place in New Zealand. In accordance with the OIA, I request the following information regarding all claims, public correspondence, and internal investigative or evaluative work relating to geoengineering in New Zealand since 1 January 2005
Public Correspondence and Claims
The total number of complaints, reports, emails, and messages received from the public relating to allegations, concerns, or evidence of geoengineering occurring in New Zealand.
Copies of all correspondence, emails, messages, and any evidence provided by the public regarding geoengineering for the requested timeframe.
Investigative Actions and Assessments:
Detailed outline of any and all investigations, research, studies, or assessments conducted by the Ministry relating to claims of geoengineering.
The names or descriptions of the team(s) or staff units responsible for investigating or evaluating such claims, and their terms of engagement or reference.
Any documentation or results from environmental testing (e.g., rainwater, soil tests, air-quality etc etc) connected to claims or suspicions of geoengineering.
All reports, findings, or analyses produced by or for the Ministry that address, refute, or otherwise relate to public claims of geoengineering in New Zealand.
Internal Communications and Decision-Making:
Copies of any internal memos, meeting notes, email correspondence, or other communications between Ministry staff relating to geoengineering claims and/or the Ministry’s responses to these claims.
Any documentation explaining the Ministry’s rationale or criteria for choosing to investigate, or not investigate, specific complaints or claims regarding geoengineering.
I request that this information covers the period from 1 January 2005 to the present day. If any part of my request is likely to be refused under the Act, I ask that you consider releasing any information that can be made available.
If the requested information is held in electronic form, I prefer to receive it in that format.
Can you also provide process documents, steps taken when environmental complaints and made by the public and how you have satisfied these requirements following complaints of this nature.
Yours faithfully,
Chris
