IR is part of the Carbon Neutral Government Programme (CNGP) set up to accelerate the reduction of emissions within the public sector.
IR’s emissions base year is 2018/19. Our 2023/24 emissions results for the mandatory emission sources as defined by the CNGP are summarised in the table below.
We are yet to commence measurement of CNGP non-mandatory emission sources that may be material. As such, IR’s emissions profile will be larger than that summarised below.
| Emissions source | Tonnes of carbon dioxide equivalent (tCO2e) in 2023-24 | Reduction against our base year | Proportion of our emissions (previous year) | Year-on year-change (previous year) | Insights *Emissions reduction activities underway |
|---|---|---|---|---|---|
| Overall |
3,015.78 | 52.8% reduction | N/A | Up 5.9% (up 27%) | IR's emissions profile is larger than that reported as we have yet to commence measurement of non-mandatory emission sources that are likely to be material. |
| Business travel |
1,570.51 (mostly air travel) | 56% reduction | 52% (45%) | Up 22% (up 320%) | Air travel was up 23% against last year (up 359% on the previous year). International travel made up 45% of air travel emissions and 36% of travel distances. |
| Freight | 863.85 (mostly mail-related) | 34% reduction | 29% (35%) | Down 12% (down 21%) | 4% reduction in mail volumes. The New Zealand Post emissions factor increased. International mail made up 6% of all paper-based mail by volume but 48% of all freight emissions (mail and courier). 90% of our mail is sent to Australia, 5% is to the UK, 2% to the USA, 2% to Singapore. |
| Energy (all sites) | 335.39 | 61% reduction | 11% (10%) | Up 20% (down 30%) | 10% decrease in energy consumption, although the Ministry of Environment Manatū Mō Te Taiao quarterly emissions factor increased. *Site consolidation/space reduction, building services upgrades and more modern sites, LED lighting. |
| Working from home | 139.71 | 68,961% increase from our base year (0) | 5% (4%) | Up 11% (up 5%) | |
| Fuel | 46.83 (mostly vehicle fleet-related) | 89% reduction | 2% (3%) | Down 36% (up 64%) |
54 out of 64 vehicles are now EVs. IR's transition to EVs is now complete in all sites except Dunedin Ōtepoti and sites that are currently being upgraded or fitted out. *100% EVs by December 2024; fleet optimisation/reduction. |
The graph below shows annual emissions by year (CNGP mandatory sources).

|---|---|---|---|---|---|---|
| Tonnes CO2e | 6,389 | 5,620 | 2,851 | 2,235 | 2,848 | 3,016 |
