Bathurst Resources reported a 0.5% increase in energy use and a 1.8% rise in total greenhouse gas (GHG) emissions in FY26, driven by higher coal processing and longer transport distances at the Stockton mine. The company used 1,082,555 gigajoules (GJ) of energy, compared to 1,076,933 GJ in FY25. Total GHG emissions, combining direct (Scope 1) and indirect (Scope 2) sources, were 116,637 tonnes of CO2e, up from 114,579 tonnes in the previous year.
Material actions and disclosures
Bathurst has continued to refine its approach to measuring energy use and GHG emissions to better identify ways to improve energy efficiency and reduce emissions. The company has also been actively involved in the Caterpillar Pathways to Sustainability Conference, focusing on fleet optimisation, energy management, and data-driven decision making.
During FY26, Bathurst replaced a 110-tonne Caterpillar D11T dozer at the Stockton mine with a smaller 70-tonne Komatsu D375 dozer, reducing the machine’s average fuel consumption from 80 litres per hour to 57 litres per hour, a 29% improvement in fuel efficiency. This switch saved approximately 35,600 litres of diesel and reduced CO2 emissions from the machine by 95 tonnes.
The company also conducted a unique emission factor study for fugitive emissions from coal mining, showing actual levels to be 24% to 34% of the default emissions factor used by the government for the New Zealand Emissions Trading Scheme (NZ ETS).
Bathurst has reported Scope 1 and Scope 2 emissions in the sustainability section of its annual report for the past four years, consistent with GRI reporting guidelines.
