A growing population will put strain on our natural resources. It is vital that we ensure resources are used efficiently and sustainably for future generations. A sustainability focus will allow us to begin transitioning Christchurch to a low carbon city.

 What this means for our district

  • Energy is used efficiently, with a greater proportion from renewable sources
  • Water is used efficiently and sustainably
  • Each person and organisation works towards zero waste
  • We transition to being a low carbon city

How we are contributing

We have recently replaced our car fleet with an electric car sharing service(external link). These cars are shared with other organisations who have signed onto the scheme, and will help council achieve our goal of being carbon neutral by 2030.

We are currently developing a policy statement on climate change, and action plans for our approach to mitigation and adaption. Our Waste Management and Minimisation Plan outlines our approach to waste minimisation, and encourages all organisations and individuals to take responsibility for reducing waste to landfill.

How you can help

Reduce your carbon footprint by taking your bike or sharing a ride with friends and family, or using public transport. Consider a battery electric vehicle if you're buying a new car, or try out a car share scheme.

If you're building a new home, or renovating an existing building, use sustainable materials and incorporate renewable energy options to save you money and help the environment. Avoid watering your garden during the the day in summer to avoid evaporation and water wastage.

Total energy consumption

Energy use has increased by 10 percent since the earthquakes, to a total of 32,600 tera joules at December 2017. Further information.

Renewable versus non-renewable energy consumption

Renewable energy as a proportion of total energy use has declined from 38 percent before the earthquakes to 33 percent in the year to June 2017. Further information.

Total waste to landfill

Waste ending up in landfill decreased by 7 percent in the year to June 2018 when compared to the previous year, with 282,000 tonnes going to landfill, however this is still 6 per cent higher than the pre-earthquake peak. Further information.

Total energy consumption

Energy consumption in the City was reasonably stable before the earthquakes, with just under 30,000 tera joules used each year. 

The earthquakes had two effects on energy use, with a decline immediately after the beginning of the earthquake sequence (for about a year), and then increased energy use as the rebuild progressed.

At the end of December 2017, the annual consumption for the City was 10 percent higher than pre-earthquake, at 32,600 tera joules.

Total energy use per person has followed a similar pattern to total consumption, except that since June 2013 it has remained at around 85 giga joules per person.

Renewable versus non-renewable energy consumption

Before the earthquakes, 38 percent of energy used in the City was from renewable sources, such as hydro and biofuels. Since the earthquakes, the proportion of renewable energy has declined to 33 percent of the total energy used.

The major contributor to this growth in non-renewable energy use has been the growth in transport energy use, especially the growth in diesel use, which increased from 46 percent to 54 percent of transport fuel consumed.

Total waste to landfill

Waste going to landfill was decreasing during the 1990s and early 2000s. It then started to increase steadily to peak at 265,000 tonnes in 2006. 

Waste generation is often linked to consumption, which tends to be higher when the economy is doing well. The global financial crisis in the mid-2000s could be one of the reasons for waste to landfill decreasing from 2006.

In 2009, the Council introduced the three bin kerbside rubbish, recycling and organic collection. This resulted in waste being diverted from the landfill, with the amount of green waste being composted doubling and the rate of recycling continued to increase. 

As a result of the demolition and rebuild programme since the earthquakes, waste going to the landfill increased, peaking at 310,000 tonnes in 2015. This was 13 percent higher than the pre-earthquake peak in 2006. As the rebuild programme progresses, we can expect the waste to landfill to decrease. This is reflected in 2018, where the waste to landfill decreased to 282,000 tonnes, the lowest it has been since 2014.
