Emissions Trading Scheme

New Zealand's Emissions Trading Scheme (ETS) is part of our response to climate change. The ETS puts a price on greenhouse gases to encourage environmentally sustainable behaviour.


How the ETS works

The ETS puts a price on greenhouse gas emissions. This provides an incentive for people to reduce emissions and plant forests to absorb carbon dioxide.

Environmental accounting

Certain businesses are required to acquire and surrender emission units to account for their direct greenhouse gas emissions or the emissions associated with their products.

An emission unit represents one metric tonne of carbon dioxide or the equivalent of any other greenhouse gas (carbon dioxide equivalent). There are lots of unit types and a variety of emission units are traded throughout the world.

It's about sustainability

The primary aim of the ETS is to encourage environmentally sustainable behaviour.

In New Zealand, sustainability is defined as:

  • good governance that supports and maintains profitable enterprises
  • encouraging and protecting the environmental integrity of both our ecosystems and the social wellbeing of our communities.

The ETS and MPI

MPI's main role is to administer the ETS for the forestry sector. We do this in partnership with the Ministry for the Environment (MfE) and the Environmental Protection Authority. We also work with MfE on climate change policy for the agriculture and forestry sectors.

Farming and the ETS

Agricultural processors must report the on-farm biological emissions associated with the production of the milk and meat they process to the Environmental Protection Authority.

The term "agricultural processors" includes:

  • meat processors
  • dairy processors
  • nitrogen fertiliser manufacturers and importers
  • live animal exporters.

There are some exemptions to these categories, including:

  • wool and velvet processors
  • egg producers.

Farmers and producers are not currently required to surrender ETS units for the biological emissions produced by agricultural activities. This is consistent with global practice – no country in the world imposes a cost on biological emissions from agriculture.

The Government has indicated surrender obligations would not begin unless:

1. there are economically viable and practical technologies available to reduce emissions
2. our trading partners make more progress on tackling their emissions in general.

The Paris Agreement

The Government ratified the Paris Agreement in October 2016. The Agreement commits New Zealand to an ambitious target – to reduce emissions to 30% below 2005 levels by 2030. To meet our commitments under the Agreement, changes may need to be made to the ETS and our other climate change policies and programmes.

Reaching our goals

Two reference groups have been established by MPI with the sectors to help investigate and manage any potential changes.

The Biological Emissions Reference Group

  • The purpose of the Group is to build robust and agreed evidence on what the sector can do on-farm to reduce emissions, and to assess the costs and opportunities of doing so.
  • The Group will not write policy or make recommendations.
  • It is joint-chaired by Chris Kerr (MPI) and Kara Lok (DairyNZ).
  • Members have signed the Terms of Reference and agreed on an initial list of priority projects.
  • MPI is leading a transparent process through the Group to commission and contract this analysis from third parties.
  • The evidence from this research will be published in the form of an interim report in early 2017, followed by a final synthesis report in late 2017.

The Climate Change Forestry Reference Group

  • The purpose of the Group is to explore and test evidence, analysis, and policy options with experts in order to inform and support officials.
  • The Group will not write policy or make recommendations.
  • It is chaired by Stuart Anderson (MPI).
  • Members have signed a Terms of Reference and have been supporting officials on a number of key issues as part of the current review of the New Zealand Emission Trading Scheme.
