Kingsgate is a signatory to the Australian Mineral Industry's Code for Environmental Management which requires signatories to commit to continual improvement and to annually audit and report their performance.

The Code was phased out in 2004 and has been replaced by Enduring Value. Enduring Value builds on the Code's platform for environmental management, but provides a Sustainable Development Framework for the industry through the implementation of a range of economic and social practices in addition to environmental practice.
