Volume of flared and vented hydrocarbon
In FY20 additional gas was sent to flare from production wells during maintenance.
FY20 data was updated in December 2020. Data was not available at the time of the initial release of the 2020 ESG Data Centre on 13 August 2020.
Includes gas venting, gas flaring and fugitive leaks from equipment and pipelines at AGL's operated oil and gas producing facilities, including exploration projects and those in development.
The data does not include vented and flared hydrocarbons from the Newcastle Gas Storage Facility as this facility does not produce oil or gas. In FY20 flared and vented hydrocarbons at this facility totalled 820 t.
The data does not include vented and flared hydrocarbons from the Silver Springs Facility including the Wallumbilla LPG plant as produced gas from the Silver Springs fields is stored and not sold in the financial year. Historical data has been updated for consistency with this approach. In FY20 flared and vented hydrocarbons at this facility totalled 280 t.
The total tonnes of gas vented and flared at each facility has been calculated in accordance with the National Greenhouse and Energy Reporting Act, and includes the use of default (method 1) emission factors for some sources of venting and general fugitive leaks.
To calculate the total vented and flared hydrocarbons relative to total production, all oil and gas production is taken into account, including production used on site, and production vented and flared.
Quantities of hydrocarbon have been rounded to the nearest tonne.
