Methodology and Data Sources

The data used on this website comes from a range of sources as outlined below.

Emissions profiles

The emissions profiles are sourced from Snapshot Climate, a website providing emissions profiles for all municipalities, states and federal electorates in Australia. These profiles have been developed in accordance with the Greenhouse gas Global Protocol for Community-Scale Greenhouse Gas Emission Inventories (GPC). The GPC Protocol is designed to promote best practice greenhouse gas accounting and reporting.

The full Snapshot Methodology including calculation methods, emission factors, and data source is available in the resources section. This methodology will be continue to be enhanced as improved data sources become available.

Snapshot is updated on an annual basis to incorporate the latest reporting periods as well as any new methodologies or changes to the GPC guidelines. This will ensure that the tool continues to meet the needs of councils and community groups. We are also working with data providers to improve the granularity and accuracy of data.

There is an approximate 1.5 year lag between the emissions occurring and when the data sets become available, analysed, reviewed and then uploaded onto Snapshot. Snapshot profiles are available for both calendar and financial years.

Further information on emissions profiles and next steps is available on the Resources page. You can also view our webinar Snapshot: How Councils and Communities Around Australia Can Use Snapshot to Drive Action, which included special presentations and updates from BZE, Cities Power Partnership, ICLEI Oceania and Ironbark.
