Our CO2-e emission reduction commitments are:
|
Scope 1 emissions
Reduced 3.4% since FY17 mainly from fleet efficiencies counterbalanced by an increase in sulphur hexafluoride (SF6) used on our network. Ausgrid has implemented an SF6 strategy to reduce these emissions.
Scope 2 emissions
Reduced 19.2% since FY17 due to grid decarbonisation, reduced electricity demand, property improvements and the installation of solar generation. Excluding line losses, Ausgrid has achieved a significant reduction of 45.7% since FY17.
Scope 3 emissions
For our waste, business travel and streetlight emissions reduced 25.5% from FY17 and continued to decrease in line with our streetlight LED program, which is the bulk of these emissions. We will be working with our suppliers to improve our understanding of our full scope 3 footprint and implement strategies to reduce this to net zero by 2050.
We produce an annual Carbon Emissions Performance Report that provides a consolidated overview of Ausgrid’s carbon emission targets, key factors influencing our performance, and measures our progress over the financial year.
We also capture data on our annual performance across our full range of emissions and report this information for compliance with the Federal Government’s National Greenhouse and Energy Reporting scheme.
* Line losses explained
Distribution network losses are the difference between the electrical energy that enters our distribution network and the energy that is delivered to our end customers. As energy passes through our network, a small proportion of this is lost as heat during the transportation.
They are the unavoidable consequence of transferring electricity across the network but can be minimised using appropriate technologies and assets.
To minimise energy costs to consumers, where practical and cost effective, we undertake activities to reduce these line losses.
As the proportion of renewable energy that we distribute increases due to the decarbonisation of energy generation in NSW, this will lower the carbon footprint of our line losses.
