New Zealand’s greenhouse gas emissions reporting

The Ministry for the Environment publishes information annually about greenhouse gas emissions in New Zealand. On this page you will find information about New Zealand’s Greenhouse Gas Inventory, the Net Position, voluntary corporate greenhouse gas reporting and emission projections.

Greenhouse Gas Inventory

New Zealand’s Greenhouse Gas Inventory 1990–2012

New Zealand’s Greenhouse Gas Inventory 1990–2012 is the official annual report of all human-caused emissions and removals of greenhouse gases in New Zealand and is a Tier 1 statistic. The inventory measures New Zealand’s progress against its obligations under the Kyoto Protocol as well as the United Nations Framework Convention on Climate Change (UNFCCC).

The 2015 inventory submission covering New Zealand national greenhouse gas emissions for 1990-2013 is planned for release in April 2015.

New Zealand's Kyoto Protocol position

Under the Kyoto Protocol, New Zealand will have to limit its levels of greenhouse gas emissions to 1990 levels, on average, during the period 2008 to 2012. If we cannot reach this target, we will have to take responsibility for any excess emissions.


The net position is a forecast of New Zealand's emissions against this target.

Each year, the Ministry for the Environment leads a whole-of-government process to update the net position for the Minister for Climate Change Issues. The latest report provides provisional data for New Zealand's balance of emission units during the first commitment period of the Kyoto Protocol (2008–2012). The data will be finalised after the UNFCCC review process is complete.

The net position webpage also includes the latest information on the provision for the Kyoto Protocol Financial Position.

The net position reports were reviewed in 2005, 2007, and 2009 by independent consultants with expertise in projecting greenhouse gas emissions. The review reports are available at the Ministry's publication page.

Overview of greenhouse gas reporting – Questions and Answers

Greenhouse gas reporting is a highly technical area. The Overview of greenhouse gas emissions reporting – Questions and Answers explains in plain language the background to the Greenhouse Gas Inventory and the Net Position. It also explains what emissions are included in New Zealand’s reporting and answers commonly asked questions about our reporting.

Guidance for voluntary corporate greenhouse gas reporting

Published annually, this guidance is for organisations who wish to voluntarily monitor and report greenhouse gas emissions for their New Zealand operations. It encourages best practice in greenhouse gas monitoring and reporting and supports voluntary greenhouse gas reporting initiatives. It endorses the referenced reporting frameworks such as The GHG Protocol, and provides information (emission factors and methods) to enable organisations to apply them.

Greenhouse Gas Emission Projections to 2030

In December 2013, the Ministry for the Environment published the Sixth National Communication under the United Nations Framework Convention on Climate Change. The Sixth National Communication includes projections of emissions and removals out to 2030 from each of the six main sectors – agriculture, energy, industrial processes, solvents, waste, and land use/ land-use change and forestry. These projections are reported in Chapter Five.
