Hamilton City Council needs to be prepared to manage the likely impact climate change will have on our city and take steps to reduce the production of greenhouse gas emissions. In 2019, we committed to developing a comprehensive and city-wide response to climate change, in partnership with Waikato-Tainui, Waikato Regional Council, and other key organisations. Our first key step was to develop an Action Plan that outlines how we are responding.
2020/2021 Climate Change Action Plan
In September 2020, the Environment Committee approved our 2020/2021 Climate Change Action Plan. The Action Plan includes four areas we are focusing on for 2020/21. They are:
Build our understanding
- Understand our greenhouse gas emissions
- Climate change scenarios and modelling
- Climate change readiness assessment
- Addressing Council emissions
- Creating a low-carbon, resilient city
- Establishing a partnership with leading organisations and businesses in Hamilton
Collaborating and capacity building
- Collaborating with other councils and community organisations
- Building our capacity to respond to climate change
Our greenhouse gas emissions targets
- 50% reduction of gross greenhouse gas emissions (excluding biogenic methane); and
- 25% reduction of emissions of biogenic methane

Reducing our emissions
Following the assessment of our greenhouse gas emissions, we developed an Emissions Reduction Roadmap that outlines how we can achieve our 50% reduction target. Some of the actions in the roadmap are already underway and others will be considered through the 2021-2031 Long-Term Plan.
In addition, through our sustainability and energy management programmes, we have implemented a number of projects and ongoing actions that reduce our organisation's carbon emissions. These include:
of Hamilton's streetlights are now new energy-efficient LED lights, reducing
energy emissions by 341 tCO2e.
signal lanterns have been replaced with LED lights.
buildings are using lower-energy LED lights
scooters and electric bikes available for staff to use for work-related trips.
a scheme for staff to purchase e-bikes via a loan, to encourage environmentally
friendly commuting to work.
- Using biogas generated from the digestion process at the wastewater treatment plant, offsetting natural gas use.
- Using electric heat pumps to control air temperature at Waterworld instead of natural gas-fired boilers.
- Replaced an LPG boiler with an electric heat pump to keep Hamilton Zoo's chimpanzees warm.
- Monitoring our energy use to identfiy energy saving initiatives
- 14% reduction in electricity and gas use from 2012
- Target of average fuel use of 10 litres/100km driving changes in our fleet
- 18,139 tonnes of waste was diverted from landfill at Council-operated waste facilities in 2018/19.
- Encouraging waste reduction in Council
Hamilton's greenhouse gas emissions
To help us identify what actions could have the biggest impact on reducing Hamilton's greenhouse gas emissions, Hamilton City Council and Waikato Regional Council commissioned an emissions inventory.
The report calculated that our city generated a total of 1,000,243 tonnes of carbon dioxide equivalents (tCO2e) between July 2018 and June 2019. Transport is the city's largest source of emissions with 635,615 tCO2e, followed by energy used for industry and in homes (29%, 276,594 tCO2e).

How is Council supporting the transition to a low-carbon city?
Some of the key actions we are delivering this year include:
- investing $10.45 million in the implementation of our Biking Plan. This includes the development of a biking and micro-mobility programme, improvements and upgrades to existing cycle infrastructure and the development of new cycleways as part of the projects detailed in our Biking Plan
- improving traffic signal optimisation to reduce travel time. In May 2019, we achieved a 27% reduction in the average travel time from Mill Street-Seddon Road to Mill Street-Victoria Street
- educating and supporting our communities to reduce waste through our Fight the Landfill campaign and our new kerbside collection services
- funding waste reduction and minimisation programmes through our annual $50,000 contestable fund
- approval of the Hamilton-Waikato Metro Spatial Plan by the Future Proof Implementation Committee, a 100-year vision and 30-year plan for how Hamilton will grow up and out.
