Why are we measuring this?
CO₂ emissions contribute to urban air pollution. By transitioning to a low-emission or zero-emission public transport fleet we can play our part in promoting a healthier environment and the adoption of newer, cleaner technologies in public transport.
This is aligned with the Government Policy Statement on Land Transport and the Ministry of Transport/Te Manatū Waka’s Outcomes Framework, as well as included in the Regional Public Transport Plan and the Regional Land Transport Plan.
By analysing this data, we can understand public transport emission trends, assess the effectiveness of initiatives, and identify areas needing further improvement.
How do we measure the result?
We gather data from our fleet operational and emissions records and the Christchurch City Council greenhouse gas emissions report (published every three years).
What work have we undertaken to contribute to this outcome?
We are aiming to have a net-carbon zero fleet by 2035 and have committed to a number of actions to transition to low emissions through our Climate Action Plan. A net-carbon zero fleet refers to achieving an overall balance between greenhouse gas emissions produced and greenhouse gas emissions taken out of the atmosphere.
In 2024/25 we welcomed 21 new zero-emission buses to the fleet, bringing the total number of electric vehicles (EVs) to 65. During the year, we reviewed the allocation of zero-emission buses across the Greater Christchurch network to better align vehicle capacity with route demand and maximise the use of EVs in the fleet. For our MyWay by Metro service in Timaru, a new contract with incumbent operator, Ritchies Transport, will see the MyWay fleet become primarily zero-emissions in 2025/26.
Through the Annual Plan 2025/26 process, we delayed funding for EV replacement and infrastructure as part of meeting government expectations around private revenue. This means we will not have funding available over the coming year to add any new EVs to the fleet.
Who else plays a role?
We can implement policies, provide funding, and enhance the sustainability of the public transport fleet by procuring low-emission or zero-emission buses and optimising routes to reduce kilometres travelled.
Partner councils, such as Christchurch City Council, Waimakariri District Council and Selwyn District Council, play a significant role by providing and maintaining the infrastructure required for public transport.
National transport agencies, the Ministry of Transport/Te Manatū Waka and NZ Transport Agency Waka Kotahi have the ultimate influence over public transport due to their key roles in setting national transport policies and funding for public transport.
Where can I find more information?
The district’s emissions are updated every three years in the Christchurch City Council greenhouse gas emissions report.
