ENVIRONMENT REPORT 2019

Other Emissions Emissions of VOCs increased by 31 per cent to just over 50,100 tonnes in 2018. VOCs are primarily associated with venting and oil-loading operations and therefore increased volumes of vented gas has resulted in an increase in VOCs in 2017–18. As detailed above, there are ongoing challenges with gas quality that preclude ignition and result in either incomplete combustion of gas via the flare system, or venting.
