Australia Emission Factors

37 emission factors for Australia, gathered from 5 parts of the GreenCalculus MasterBrain — fuel combustion (18), mobile combustion (16), carbon pricing (1), grid electricity intensity (1) and transmission and distribution losses (1) — so figures normally spread across separate reference pages sit on one. Drawn from World Bank Carbon Pricing Dashboard — compliance instruments (ETSs and carbon taxes): design, GHG coverage and price, per State and Trends of Carbon Pricing 2025, National Greenhouse Accounts Factors 2025, Ember Yearly Electricity Data (2025 release) and World Bank Open Data — Indicator EG.ELC.LOSS.ZS: Electric power transmission and distribution losses (% of output) and read live from the data layer on every page build. They span 8 units of measurement, which is why the spread below is reported per unit and never blended.

Where these factors also appear

Each factor here also appears on the reference page for its own family — Fuel Combustion Emission Factors, Mobile Combustion Emission Factors, Carbon Price Reference Values, Grid Electricity Carbon-Intensity Factors by Country and Grid Transmission & Distribution Loss Factors — where it sits alongside every other country. This page is the same data cut to one country, for when that is the question being asked.

What this group contains

Figures are computed per unit and never blended: a median across different units would be arithmetically valid and physically meaningless. 5 further units in this group have fewer than 3 factors and are counted above but not described.

Values change between editions. Quoting the MasterBrain version is what lets a reader resolve the exact number you used — see the change record above for factors in this group that have moved.

Both responses carry an X-GC-Version header, so a consumer can detect a new edition without diffing the payload. The CSV filename carries the edition too, so two downloads months apart do not collide.

All factors

Last changed names the data-layer edition in which a factor last took a new value, reconstructed from every released edition since v2025.13. A dash means the value has not moved since tracking began — which is the answer to "is the figure I used last year still current?".
