Environmental Factor Guideline – Greenhouse Gas Emissions

The purpose of this guideline is to communicate how the factor Greenhouse Gas Emissions is considered by the Environmental Protection Authority (EPA) in the environmental impact assessment (EIA) process.


When the original Environmental Factor Guideline – Greenhouse Gas Emissions (EFG-GHG) was published in April 2020, the EPA committed to a 12-month review to ensure the guidance remained contemporary.

In July 2021 the EPA commenced its review of the EFG-GHG and an 8-week public consultation of the draft revised guidelines ended on 21 September 2022.

During the consultation, 1088 submissions were received from the public, industry, peak bodies, government and non-government groups. On 3 February 2023, the EPA published a summary of public submissions and advice received.

On 5 April 2023 the EPA published its revised EFG-GHG.
