| NO SIGNIFICANT CHANGE
(note: trend indicator above is relative to 2007 WPI baseline year total emissions).
National annual greenhouse gas emissions appear to have stabilised.
This indicator shows the trend in national annual total greenhouse gas emissions and the latest available Waikato regional information.
Climate change is an issue requiring urgent collective action at the regional, national and international levels. According to the Intergovernmental Panel on Climate Change, people’s activities are affecting the earth’s energy ‘budget’ through increases in greenhouse gas emissions, the use of aerosols and by changing land surface properties. Atmospheric concentrations of important greenhouse gases such as carbon dioxide, methane, and nitrous oxides have increased over the last few centuries.
The effects of these gases have been documented in compelling evidence of climate change gathered from scientific observations of changes to the atmosphere, land, oceans and cryosphere (for example, ice core records). There is evidence of climate change effects, including raised temperatures and sea levels and increased frequency of extreme weather events. The occurrence of these changes is projected to become more pronounced, and the rate of change more rapid over time. Changes in climate can have major impacts on our safety, health, economy and infrastructure, and how and where we can live.
|Year||National total gross greenhouse gas emissions (000 tonnes C02 equivalents)|
New Zealand’s contribution to global gross greenhouse gas emissions is small (0.17%), but we have the fifth-highest level of emissions per person of the 35 countries in the Organisation for Economic Cooperation and Development (OECD, 2017; cited in MfE & SNZ 2017).
According to latest available information, New Zealand’s annual gross greenhouse gas emissions in 2017 were 80.9 million metric tonnes of carbon dioxide equivalent (t CO2e). This is 23% higher than in 1990.
National gross greenhouse gas emissions grew rapidly over the period 1990 to 2006 and have remained high. There has been no significant trend in annual emission levels since 2007, the baseline year for Waikato Progress Indicators (WPI) progress monitoring.

DATA SOURCE AND SUPPORTING INFORMATION
National data are published annually in April through the Ministry for the Environment (MfE) website - New Zealand’s Greenhouse Gas Inventory(external link). Summary data was sourced from the Interactive Emissions Tracker data (gross emissions, time series).
Figures relate to New Zealand’s annual total greenhouse gas emissions (Gg CO2 equivalent). Total emissions include those from the energy, industrial processes, solvent and other product use, agriculture and waste sectors, but do not include net removals from the ‘LULUCF’ sector (Land Use, Land Use Change and Forestry).
New Zealand’s total (and net) emissions under the Climate Change Convention from 1990 to most recent year are plotted in the Inventory Report, and latest figures are cited and tabulated in the text and downloadable.
Information on trends in the link between greenhouse gas emissions and GDP growth are from Statistics New Zealand’s Environmental-economic accounts 2018: www.stats.govt.nz/information-releases/environmental-economic-accounts-2018(external link).
Projections of New Zealand's greenhouse gas emissions are published in national communication and biennial reports tracking progress towards meeting internationally-agreed climate change commitments: http://www.mfe.govt.nz/climate-change/what-government-doing/progress-towards-our-international-climate-change-commitments(external link).
