Closes 31 May 2024

Opened 8 Apr 2024

Results expected 31 Dec 2024


To ensure that Aotearoa New Zealand's 2050 emissions reduction target remains fit for purpose, the Commission is required to review it every five years and provide independent expert advice to the government of the day on whether any changes should be made.

We are currently doing our first such review. We have released a discussion document on this and are seeking your feedback.

The emissions reduction target was set by Parliament to focus Aotearoa New Zealand’s efforts on climate action. It provides a consistent signal to government, businesses and communities so they can plan long-term action and investment. However, if it is no longer fit for purpose then it will lead the country on the wrong path.

To ensure that the target remains fit for purpose we are required to review it every five years, and provide independent expert advice on whether any changes should be made. We are doing the first such review now.

The bar for change is high – we can only recommend a change to the emissions reduction target if:

  • there has been or likely will be a significant change since 2019 in specific criteria (specified in section 5T of the Climate Change Response Act) – e.g. if there is significant new evidence or a new global context for change, and
  • we are satisfied that this significant change justifies a change to the target.

If we consider that a change to the target is justified, we must advise the Government on how the target should be altered.

These could be changes to what the components are, what gases they apply to, when they have to be met by, and how much can be met in Aotearoa New Zealand or paid for overseas.
