Energy affordability and decarbonisation
Our Field Service Provider Omexom uses a truck-mounted gas leak detection system known to ‘smell’ minor gas leaks by simply driving down the street at normal speed, with GPS technology marking the exact location of any leaks detected. This enables us to find and fix leaks faster, reducing carbon emissions and improving the safety of the public and environment.

Our carbon footprint Vector measures and reports its emissions in accordance with The GHG Protocol Standard and The GHG Protocol Value Chain Standard annually. Our base year for emissions reporting is 1 July 2019 to 30 June 2020. Detailed information on organisational and operational boundaries, methodologies used and emissions trends over time can be found in Vector’s GHG emissions inventory report FY23. In the year to 30 June 2023, we’ve achieved a reduction of 14.7% across all scopes from our base year FY20. The most significant reduction in scope 1 emissions can be observed with gas distribution fugitive emissions, driven by the initiatives outlined on p25. Diesel use in generators has also seen a reduction, while vehicle fleet and sulphur hexafluoride (SF 6 ) emissions increased.
Scope 2 emissions have increased, despite a decrease in electricity losses across our network, due to a noticeably higher emissions factor used for this year’s calculation compared to previous years. An increase in Vector’s own electricity consumption can be attributed to a growing uptake of Vector’s free EV charging infrastructure across Auckland. Value chain emissions across

scope 3 have increased by just over 1% compared to FY22. However, when comparing against our FY20 base year, emissions across scope 3 have decreased by 15%. Further details on our emissions by scope and category can be found in Vector’s GHG emissions inventory report for FY23, available on our website.
