Additional data and methodology updates have been applied to previous year’s Snapshot profiles. This means your Snapshot profile will have changed. Notable changes include:
- DNSP data in VIC now includes data from Jemena so every municipality in VIC has DNSP data for electricity emissions.
- DNSP data in VIC has been extended to include commercial and industrial sectors. For NSW and QLD, DNSP data is still remains limited to the residential sector.
- DNSP data in NSW now includes Essential Energy for residential electricity emissions.
- Key emitters data is now sourced solely from the Safeguard mechanism. This data is of very high quality. Previously Snapshot also used key emitters data from the NPI registry, NGERS and Open Street Maps (now Corelist). This data is reliant on estimated employees and is of lower quality.
- Addition of Marine Transport emissions as a new emissions source. This will not affect the majority of profiles.
These changes will be reflected differently for different councils depending on the share of industrial emissions and whether the DNSP data updates apply. An example of the changes for Hobson’s Bay City Council for the municipality’s 2021/22 profile are described below.
- Overall emissions have increased 12%. Largely driven by an increase in Fugitive emissions.
- Residential electricity has increased 194% due to the introduction of Jemena DNSP data. Previously only Powercor data was available for Hobsons Bay.
- Electricity Commercial has decreased -48% and Industrial -45%. Due to the introduction of DNSP data.
- Freight Transport has increased 50%. Safeguard facilities now exclude an electricity component. This has resulted in a reallocation of emissions which were previously allocated to Industrial Electricity, to other industrial sources.
- Domestic Marine. There are 17,000 emissions associated with domestic marine which are new emissions not accounted for previously.
- IPPU increase 13%. Safeguard facilities now exclude an electricity component. This has resulted in a reallocation of emissions which were previously allocated to Industrial Electricity, to other industrial sources.
- Fugitive Emissions increase 48%. Safeguard facilities now exclude an electricity component. This has resulted in a reallocation of emissions which were previously allocated to Industrial Electricity, to other industrial sources.
