Our greenhouse gas (GHG) emissions are small compared with those of other developed nations, but we have committed to being part of the global response to climate change. New Zealand's greenhouse gas inventory is an annual report on all of the country’s human-induced GHG emissions and removals of GHG emissions. The inventory is produced as part of our obligations under the United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol.
Some GHG emissions are removed, primarily by forests. Net emissions represent the total amount of gas contributed to the atmosphere but gross emmissions are also provided for New Zealand.
This dataset relates to the "New Zealand's greenhouse gas emissions" measure on the Environmental Indicators, Te taiao Aotearoa website.

"New Zealand’s land area has been divided into 500 land environments, each defined by their unique climate, topography, and soils. The extent to which indigenous vegetation is represented in these different land environments, and how that vegetation is formally protected, is described by ‘threatened environment’ categories. These categories can be monitored to help us understand the effects of land cover change on indigenous biodiversity.

This data set relates to the "Indigenous cover and protection in land environments" measure on the Environmental Indicators, Te taiao Aotearoa website."

River water quality water is valued for many reasons including ecological function and habitat, recreational value, its role in supporting people and industry, and its cultural significance. Nutrients such as nitrogen and phosphorus are essential for plant growth, however too much in rivers can lead to ‘nuisance’ growths of river algae and aquatic plants, degrading habitat. High concentrations in the form of ammoniacal nitrogen and nitrate-nitrogen can be toxic to fish and other aquatic animals. Water clarity is a measure of underwater visibility, and affects habitat of aquatic life such as fish and birds, and can also impact on aesthetic values and recreational use of rivers and streams. Escherichia coli bacteria can indicate the presence of pathogens (disease-causing organisms) from animal or human faeces, which can cause illness.
State (percentile) results for the following parameters, by monitored site for the period 2009–2013, are provided. Refer to Larned at al (2015) for further details.

 Clarity (CLAR), m
 Ammoniacal nitrogen (NH4N), mg/m3
 Nitrate nitrogen (NO3N), mg/m3
 Total nitrogen (unfiltered) (TN), mg/m3
 Dissolved reactive phosphorus (DRP), mg/m3
 Total phosphorus (unfiltered) (TP), mg/m3
 Escherichia coli (ECOLI), n/100 mL

Road motor vehicles emit a range of air pollutants from their exhausts, and from brake and tyre wear. They are the main human-made source of nitrogen oxides and carbon monoxide emissions. Exposure to these pollutants can damage health, with effects ranging from respiratory irritation to cancer.

Road motor vehicles range from passenger vehicles to heavy commercial vehicles, including petrol and diesel vehicles. Vehicles for use in farm and construction are not included. While road motor vehicle travel predominantly involves petrol vehicles (approximately 73 percent of vehicle kilometres travelled), diesel vehicles (approximately 27 percent of vehicle kilometres travelled) contribute the majority of air pollutants from road motor vehicles – specifically particulate matter and nitrogen oxides (NIWA, 2015; Parliamentary Commissioner for the Environment, 2015).

Lightning is the discharge of electricity from thunderstorms. Ground strikes can cause significant damage to property and infrastructure, and injure or kill people and livestock. Lightning is often associated with other severe weather events, such as strong wind gusts. Thunderstorms may increase in frequency and intensity with climate change.

The REC groups rivers and parts of river networks that share similar ecological characteristics, including physical and biological. Rivers that share the same class can be treated as similar to one another and different to rivers in other classes. The REC classification system groups rivers according to several environmental factors that strongly influence or cause the rivers’ physical and ecological characteristics (climate, topography, geology and land cover). A catchment is a polygon that defines the upstream watershed of a river system or sub-system. Land cover within the catchment was used to populate the river classification factors (see table 1.1 of the User Guide data.mfe.govt.nz/document/123-rec-user-guide-2010/ ).

A spatial dataset identifying a set of environmental conditions that have potential to inhibit growth of newly-established woody vegetation such that it might not reach a ‘forest’ status (defined as greater than 30% cover of trees of 5 m height) within a 30-40 year timeframe.

Inclusions: temperature, moisture availability, edaphic conditions, coastal exposure, and land instability

Exclusions: herbivory, competition, external gene pools, availability of seed sources and dispersers, and also fire

This ELF layer is designed to provide a concise evidence source to guide decision making regarding the potential for naturally regenerating species to reach the criteria for Kyoto-compliant forest. Due to the variable quality in the source data used to compile this layer it should only be considered to provide guidance and should not be used as authoritative for forest eligibility/ineligibility under any government scheme.

The ocean waters surrounding New Zealand vary in temperature from north to south. They interact with heat and moisture in the atmosphere and affect our weather. Long-term changes and short-term variability in sea-surface temperatures can affect marine processes, habitats, and species. Some species may find it hard to survive in changing environmental conditions.

This layer shows annual average sea surface temperature for 2009 as part of the data series for years 1993 to 2013.

NIWA’s sea-surface temperature archive is derived from the Advanced Very High Resolution Radiometer (AVHRR) satellite data it receives from the National Oceanic and Atmospheric Administration. The archive provides high spatial (approximately 1km) and high temporal (approximately 6-hourly in cloud-free locations) resolution estimates of sea-surface temperatures over the New Zealand region, dating from January 1993. Uddstrom and Oien (1999) and Uddstrom (2003) describe the methods used to derive and validate the data.

New Zealand’s four million km2 marine environment is diverse, with a range of coastal habitats and offshore seabed environments. There are also many marine species unique to New Zealand. Marine protected areas conserve or manage some of these unique habitats and species, while a range of other tools also provide marine protection. We report on the area covered by these tools as an indirect measure to understand the state of the marine environment.
Benthic protection areas (protected seabed areas) are one of the marine protection tools used. They are designated areas in the exclusive economic zone, which extends from the 12 nautical mile seaward limit of the territorial sea to the 200 nautical mile limit. Bethnic protection areas protect seabed habitats through the prohibition of bottom trawling and dredging. There are some areas where seamount closures overlap with benthic protection areas. In these cases the seamount closure restrictions apply.
