Creating a new energy future – a bold vision
CLIMATE ACTION: DECARBONISATION
alongside our suppliers to increase data availability and report on any other material sources in the future. In the past year, our carbon footprint (Scopes 1, 2, and 3) reduced by 12%, a reduction of just over 210,000 tonnes of CO 2 equivalent (tCO 2 e). Within Scope 1, this is primarily due to a reduction in gas leaks on our gas network as well as lower diesel consumption for the use of generators on our electricity network. We are continuing to refine our gas loss reduction plan, and investigate methods to reduce back-up diesel combustion. We have also developed a strategy for switching our remaining light combustion vehicles to electric vehicles. Within Scope 2, electricity line losses have increased, while our company’s own electricity consumption has reduced by 4%.
Our indirect emissions covered in Scope 3 also reduced noticeably. To a large extent this can be linked to a reduction in sales volumes by Ongas Natural Gas, but also reduced fuel use by our Field Service Providers for network maintenance and a significant reduction in business travel. We are actively investigating renewable options for our natural gas and LPG business.
The transition to a low- carbon economy will require commitment from the whole energy sector. Vector has
included decarbonisation as an intrinsic part of our Symphony strategy, making climate action a priority goal. Identifying areas to decarbonise, both internally and externally, and working on strategies to achieve our targets has been a focus
throughout the past year. Our carbon footprint
12 % REDUCTION IN OUR CARBON FOOTPRINT IN THE PAST YEAR (SCOPE 1, 2, AND 3)
This year we sought to gain a more comprehensive understanding of emissions created across our entire value chain. In addition, the divestment of the Kapuni gas treatment plant represented a significant change in emissions. To allow for meaningful and useful comparisons over time we recalculated our emissions for FY20, and reset our base year to the same. Vector measures its greenhouse gas emissions in alignment with the Greenhouse Gas Protocol. All applicable Scope 3 emissions that are material and accurately quantifiable are reported, along with otherwise relevant Scope 3 emissions.** Some embodied emissions for purchased products were also identified as material, however due to limited embodied emission data availability, are not included in this disclosure. It is our intention to work

* Although only divested in March 2020, Kapuni emissions are excluded in the updated FY20 footprint calculation to facilitate future comparisons to FY20 as our base year. ** Scope 3 emission sources include upstream well-to-tank emissions for fossil-gas (Category 1) and fuel (Category 3), fuel consumed by field service providers (Category 1), T&D losses for consumed electricity (Category 3), business travel (Category 6), combustion of sold and distributed fossil-gas (Category 11), and investments with more than 10% share (Category 15, accounting for proportional Scope 1 and 2 emissions).
