Reducing our carbon footprint

Maritime New Zealand is proud to be a Toitū carbon reduce certified organisation.

Toitū certification is awarded to organisations that are actively measuring and managing their carbon footprint. Toitū carbon certification

It means the measurement of our greenhouse gas emissions is in line with the international standard for carbon footprints, ISO 14064-1, has been verified by an independent audit and we have committed to managing and reducing those emissions from our 2019/20 baseline with annual measurement to verify our progress.

We have set the following organisational emission reduction targets:

  • 2025 target: 21% reduction in scope 1, 2 and 3 mandatory[1] emissions by July 2025, based on FY2019/20

  • 2030 target: 42% reduction in scope 1, 2 and 3 mandatory emissions by July 2030, based on FY2019/20

These are ambitious targets that reflect our intent to respond to the urgency of the climate crisis through science-aligned targets (1.5 degrees Celsius emissions reduction pathway).

These targets align with requirements of both the Carbon Neutral Government Programme and Toitū carbonreduce programme.

Our total emissions for the 2022/23 financial year were 1608 tonnes of CO2-e. Most of our emissions came from our Search and Rescue (SAR) activity, air travel, and fuel consumption from our fleet.

Our largest emissions source this financial year was from our SAR activity. There were a number of significant SAR events in FY22/23. In particular, our contribution to the Cyclone Gabrielle response resulted in a considerable spike in our emissions. As SAR is an activity which we cannot directly control and is a preservation of life activity, we have excluded that source from our reduction targets.

Once our SAR activity is removed, there has been a 15% reduction in our controllable emissions since our FY2019/20 base year that sees our performance tracking in line with achieving our 2025 targets.

[1] Mandatory refers to Carbon Neutral Government Programme (CNGP) mandatory sources as detailed in the Ministry for the Environment’s guidance to CNGP agencies in May 2023. As at 2023, the following sources are included within our 2025 and 2030 targets: Scope 1 Diesel and Petrol; Scope 2 Electricity; Scope 3 air travel domestic and international, freight and courier, hotel stays, taxi, private car mileage, contractor use of vehicles, rental vehicles, helicopter business travel, working from home, transmissions & distribution losses, water supply, waste water services, paper use, and waste.
