A central part of our goal to be an eco-city is achieving a 30% reduction in Palmy’s greenhouse gas emissions by 2031. This target is our part of a national effort to make the whole of New Zealand carbon neutral by 2050.
As part of a worldwide effort to keep global warming to +1.5 degrees or less, the New Zealand government declared a climate emergency in December 2020. This triggered programmes like the Emissions Trading Scheme and the National Emissions Reduction Plan.
There is now a sustained national effort to get to net zero carbon emissions across Aotearoa by 2050. Put simply, net zero means cutting greenhouse gas emissions to as close to zero as possible, with any remaining emissions re-absorbed by natural sources like forests.
This effort will require real action across every sector of New Zealand’s economy. It means Council will need to find ways to significantly lower our own emissions. We’ll also need to use our regulatory powers to encourage others to lower theirs. We adopted many of the principles of the government’s net zero plan in our Eco City Strategy and Climate Change Plan.
Meeting this target is not something Council can do alone. It’s only with widespread buy-in and effort from our community that Palmy will be able to create a climate-resilient future with cleaner air and energy, better transport options and healthier homes.

Recent changes in our local weather patterns have indicated some of the ways Palmerston North and the wider district may impacted by climate change. Regional reports on the estimated changes and possible flow-on effects can help us understand and plan for the future.
While Manawatū District has less populated areas of coastline to defend against coastal erosion than many other districts, we still have plenty of water around!
One estimated impact of climate change for our region is that more heavy rainfall will increase the risk of flooding, making it up to four times as frequent by the end of the century. This could have large implications for areas already prone to river flooding, like the Manawatū and Rangitikei flood plains.
Because our region has diverse landscapes, other areas will probably see more droughts. Both these aspects are likely to increase erosion, slips and landslides.
The National Institute of Water and Atmospheric Research (NIWA) has prepared a report on likely impacts of climate change for the Manawatu-Wanganui region.
Horizons has collaborated with other councils in the region to produce a regional risk assessment and climate action strategy.

Keeping an annual record of our annual emissions across the city allows us to measure how our progress compares to our eco city targets.
Transport is by far Palmy’s largest carbon contributor. Nearly half our citywide emissions are transport related. Meeting our carbon goal will rely heavily on helping people to drive a lot less.
Forestry has also had a large effect on the carbon levels for Palmy city. Citywide emissions rose by approximately 80,000 tonnes between 2020 and 2021 year with the recent cutting down of mature pine trees in surrounding areas accounting for 68,000 of this increase.
Growth in our population will mean increases in demand for goods and services. New technologies, incentives, regulatory changes and cleaner options will all play their part in using our resources more efficiently to help Palmy grow sustainably.
Last year’s inventory of Palmy’s carbon emissions is below.
To help Palmy reach its carbon reduction targets we need to do our part by reducing greenhouse gas emissions from Council's own activities.
Since we first began monitoring in 2016 Council has reduced our annual emissions by 6,004 tonnes carbon dioxide equivalent (tCO2e), or 22.7%. It’s a good start. But if we’re to meet our target of 30% emission reduction across the city by 2031, we’ll need to drive our own efforts forward at pace and encourage behaviour change within our community as well.
To continue cutting our Council emissions our elected members have created a low carbon fund, which invests $1 million a year in lowering carbon outputs from our operations. So far, we’ve used this toward more efficient streetlights, boilers, systems at the Lido and electric pool cars for our officers.
The chart below shows Council's carbon emissions from 2016 to 2021.
In the lead-up to the 2023-24 10-Year Plan, our climate change team will be looking into what other low carbon technologies and processes we can adopt in our mission to lower our carbon use as much as possible.
