We have clean water, fresh air and healthy soils. Well-functioning and diverse ecosystems make up an environment that can support our needs. Resources are used efficiently. There is minimal waste and pollution.
Good air, water and soil quality, and reducing waste are all essential to maintaining a healthy environment and ensuring the sustainability of resources. Water-based recreational activities are part of an outdoor-focused way of life and it is essential that the water is of a high quality. Protecting land through open space covenants also helps maintain ecosystem diversity, along with natural and cultural heritage. Primary land uses such as agriculture, dairying and cropping are key contributors to an economy but they can have a negative influence on the environment.
16 indicators are used to measure progress towards the healthy environment outcome (defined above). Data relating to each individual indicator (for the 2001 to 2017 period) is provided via the menu below. The healthy environment index (pictured below) shows the composite average of the individual indicators.
As there is only one community outcome under environmental well-being, the same index is applied to both the well-being aspect and the community outcome area.
The GPI counts our health-care costs created by smoking, not exercising, eating poorly and becoming obese, as costs, not gains, to the economy.

Greenhouse gases (GHGs) such as carbon dioxide, methane, and nitrous oxide are emitted through a variety of human activities. Air travel, driving petrol and diesel powered vehicles, using non-renewable electricity from the national grid, harvesting trees and farming animals are some of the activities that generate GHG emissions in the Wellington region. GHG emissions drive climate change and are considered a proxy for resource depletion. Climate change is now widely acknowledged as the most serious environmental challenge of our time and, without stringent and widespread emission reductions, is expected to generate serious economic and social consequences.
The net annual emissions of all greenhouse gases divided by the estimated resident population.
2016 Community Greenhouse Gas Inventory for Wellington City and the Greater Wellington Region 2000-2015, link to report below.
Last updated May 2016
This indicator is derived from the 2016 Community Greenhouse Gas Inventory for Wellington City and the Greater Wellington Region 200-20015.. The inventory measures regional greenhouse gas (GHG) emissions from the following sectors: stationary energy (such as electricity and gas), transport (including domestic aviation), industrial processes (such as gases used in refrigerators and air conditioning systems), agriculture, waste and forestry.
The emissions are expressed as ‘net’ because the inventory takes into account all forests planted for timber production and native forests managed for conservation values. Both the emissions generated when trees are harvested, and the carbon sequestered while trees are growing is taken into account. For more detail, refer to the URS GHG Inventory.
A national comparison is not included because the methodology used to calculate the regional inventory differs from that used to create the national inventory. Both methodologies follow guidelines specified by the Intergovernmental Panel on Climate Change (IPCC), but because they measure emissions at differing scales, differing methodologies are applied.
Data for individual TAs is not available, as data was not collected at the TA level for the 2016 report. The previous report, the 2014 Greenhouse Gas Inventory for the Wellington region contains TA level data by sector. Note that for some sectors the methodology used in the 2014 report differs to that of the 2016 report. These changes are explained in the Executive summary of the 2016 report, page (i).
Indicators are updated in May and November each year; for those indicators where new data or survey results have become available.
 Only emissions from ‘managed lands’ are included. Due to limited data availability only emissions from forest land and grassland with woody biomass were included (incorporates carbon sequestered in above ground biomass, below ground biomass, dead organic matter and litter). It was assumed that there are no significant changes in the carbon pools of cropland, wetlands, settlements and other land uses.
