In 2018, the Australian Government identified the management of emissions from non-road diesel engines as a priority action under the National Clean Air Agreement. Since then, significant developments have taken place, bringing us closer to a national approach to tackle this issue.  

Recently, on May 24, 2023, the Department of Climate Change, Energy, the Environment, and Water (DCCEEW) released the draft Impact Analysis, formerly known as a Regulation Impact Statement, for the Non-Road Diesel Engine analysis. The purpose of this analysis is to evaluate the potential impacts and recommend a way forward in managing emissions from non-road diesel engines. 

After considering various scenarios, the draft Impact Analysis has recommended the introduction of emission standards aligned with international best practices, specifically the US Tier 4f standard, and for it to be introduced as soon as practicable. 

CMEIG has actively participated throughout the process including a recent meeting with DEECCW. As a key representative of the construction and mining equipment industry, CMEIG plays a vital role in providing feedback and insights to shape the final regulations. 

CMEIG will be submitting a formal response to the released Impact Statement by the 14 July 2023 deadline. The submission key messages include: 

  • Constructively test some of the assumptions made in the DEECCW modelling.  
  • Ensuring that the contribution of alternate engine technologies is accounted for in any analysis of emissions reduction by the industry. 
  • That there is adequate notice (minimum two years) from the time DEECCW finalise and announce any regulatory decision. This grace period is crucial to allow the industry’s supply chain to effectively manage and adapt to potential regulatory changes. 

Following the public review process, the Impact Analysis will be carefully assessed by the Government. Toward the end of the year, a decision will be made on whether to implement regulations and, if so, how best to proceed. 

The progress made in the Non-Road Diesel Engine analysis is a significant step toward managing emissions and promoting a cleaner environment. CMEIG’s active involvement ensures that the construction and mining equipment industry’s perspectives are heard, contributing to a balanced and effective approach. As the year progresses, we eagerly await the Government’s decision on regulations and look forward to a sustainable future for the industry.
