This page contains further information on reporting requirements for agencies in Tranche 1.
Tranche 1 reporting covers the 2021/22 financial year (1 July 2021 - 30 June 2022) from 39 government departments, departmental agencies and the non-public service departments in the Executive branch.
Participating organisations are required to report:
The remaining Tranches 2 and 3 (all Crown agents, the tertiary sector (including the New Zealand Institute of Skills and Technology) and state-owned enterprises) will report to the programme in December 2023 for the 22/23 financial year. Tertiary Institutions may report on a calendar year basis.
Organisations will report by 1 December each year going forward.
Agencies are required to obtain independent third-party assurance that their emissions inventory has been prepared in accordance with ISO 14064-1 and/or the GHG Protocol for their base year and current year of reporting. Acceptable assurance levels include reasonable and limited assurance.
All submitted inventories have been verified apart from the New Zealand Intelligence Service and the Government Security Bureau, who are in the process of providing independent assurers access.
Organisations select their own base year, no earlier than 2015/16 and no later than 2021/22 for Tranche 1 and 1 July 2021-30 June 2022 for Tranches 2 & 3. The ‘base year’ referred to at the programme level represents the cumulative total of emissions from each agency's base year.
In 2022, Tranche 1 agencies set targets which add up to a 22% gross emission reduction across their total reported emissions by 2025, and 42% by 2030.
CNGP organisations are required to set gross emissions reduction targets for 2025 and 2030 consistent with a 1.5 degree pathway, measured against a base year and based on the reduction potential within the organisation. These are called ‘organisation targets’.
For CNGP purposes, a 1.5 degree pathway means the IPCC scenario that gives at least a 50% probability of limiting global warming to 1.5 degrees Celsius this century with low/no overshoot, which is the scenario used by the Science Based Targets initiative, an approach adopted by many organisations around the world as best practice. In practical terms, this equates to a minimum 42% reduction in gross emissions by 2030, based on a 2020 base year.

The GHG Protocol places emission sources into scope 1, scope 2 and scope 3 activities.
All agencies (around 130) that must follow the Government Procurement Rules must now transition their light vehicle fleets to battery electric vehicles (BEV), or plug-in hybrid electric vehicles (PHEV) if a BEV is not appropriate, unless there is an operational requirement that prevents them from doing so.
Light fleet vehicles are defined as those that weigh 3,500kg or less.
NABERSNZ (the National Australian Built Environment Rating System New Zealand) is a system for rating the energy efficiency of office buildings.
Since January 2021, agencies that are covered by the government property mandate have been required to get a NABERSNZ rating by December 2025, for all office buildings where they own or lease an area of 2000m2 or over.
A NABERSNZ assessment takes 12 months and when entering a new lease or renewing an existing lease, agencies should target a minimum rating of 4 stars for existing buildings and 5 stars for new buildings.
Two types of NABERSNZ ratings are being obtained by agencies, a base build rating for all buildings within scope of the NABERSNZ requirement, plus a tenancy rating where Government occupies ≥ 5,000 m2 in a building.
