Climate change

Our city continues to face the effects and impacts of climate change. We are in the early stages of developing a strategy, Te Ao Hurihuri, and will look to our community for input and direction in the coming months


Porirua City Council declared a climate change emergency on 26 June, 2019, setting the scene for Council to take a greater emphasis on this issue. 

Te Ao Hurihuri (ever changing world) will be developed in the coming weeks and months, with community engagement a vital part of the process - building on the good work already being done on the city's Growth Strategy and the District Plan.

See our press release from 27 June on Te Ao Hurihuri here.

Porirua's 2050 emissions calculator 

What choices will see the biggest reduction in the Wellington region’s emissions? What do we need to do in order to meet emissions targets? The Wellington Region 2050 Emissions Calculator lets you model changes within the Greater Wellington Region in order to forecast our future emissions.

This tool puts you in charge of the Wellington Region by allowing you to adjust key levers relating to energy supply and demand, transport, land use and agriculture, and more. By adjusting these levers you can see what will offer the biggest emissions reductions for the Greater Wellington region and the individual council areas.

Check it out here and let us know what you think.

District Plan and coastal hazards

Porirua City Council is undertaking a full review of the District Plan. The District Plan tells us what we can and can’t do with our land. It makes rules about where we can subdivide, what activities we can do and where we can do them. 

As part of this review, the government requires us to address a lot of things to keep our communities safe and to protect the local environment. We have engaged the Focus Resource Management Group to help us to understand the coastal hazard risk in Porirua. 

First step

Our coast differs across Porirua. To understand the specific coastal environment, community values and coastal hazards that affect particular areas we have held two rounds of community workshops.

Coming up

In July 2019 we are running another round of workshops led by Jim Dahm of Focus Resource Management Group. We will present our draft coastal hazard maps to the community and hear feedback at this time, as well as present some potential options on how we might look to address these hazards in our District Plan (for more information see our coastal hazards webpage).

All are welcome to join in on the kōrero, with dates and locations as follows:

Greenhouse Gas Inventory

Wellington Region 

Community Greenhouse Gas Inventory 

This report was released in 2015 by AECOM for Greater Wellington Regional Council. Some key findings for the region, and for Porirua City specifically include:

  • The region's emissions per capita were measured at 4.18 tonnes 
  • The rate of emissions has fluctuated since 2001, with a consistent downward trend between 2006 to 2010 then peaking at 4.36 tonnes per capita in 2011
  • The period 2013-2015 has been a time of relatively stable emission rates.
  • Most emissions come from stationary energy and transport, compared to the Wairarapa where most come from agriculture.
The main factors in reducing greenhouse gas emissions in the Wellington region at this time were:

  • more electricity being generated from renewable sources (wind and geothermal),
  • a decline in electricity consumption
  • relatively stable overall consumption of road transport fuels (petrol use has declined while diesel has gone up)
  • landfill gas recovery systems being installed
  • more waste being diverted from landfills.
