For several years, Murdoch Ltd has been producing nitrogen fertiliser in Western Australia. The company is redirecting gas supplied from a discovery in the Perth Basin to their fertiliser factory in a bid to achieve zero carbon emissions. Murdoch Ltd.s operations have led to the contamination of land around the factory. Murdoch Ltd.s policy is only to clean up contamination when required to do so by law and currently there are no laws relating to environmental contamination. However, on 31 December 2021, it is virtually certain that Western Australia will enact new legislation in early 2022 to require the clean-up of land that has already been contaminated. Murdoch Ltd has estimated that the costs to clean up the contamination will be $1.2 million.
