We use standard methodologies to calculate direct (Scope 1[1]) greenhouse gas (GHG) emissions, including direct measurements of energy sources consumed, calculations based on site-specific data and calculations based on published criteria (such as emission factors and global warming potential).

In general, we report our emissions and energy consumption under the country of operation’s regulations and policies. For example, in Australia, we report our emissions and energy consumption under the National Greenhouse and Energy Reporting System (NGER).

The majority of our GHG emissions generated from energy use during mining and processing. Energy consumption for 2018, 7.0 PJ, increased slightly over 2017 levels. Scope 1 and Scope 2[2] emissions, 509 ktCO2e, were slightly higher due to:

  • 100% utilisation of mining and concentrating activities at J-A after recommencement at the end of 2017;
  • 100% utilisation of Narngulu MSP; and
  • commencing construction of the Cataby mine.

Scope 1 emissions at our North Capel synthetic rutile operation are largely related to the use of coal in the process, which makes up 46% of energy resources used. In the synthetic rutile production process coal is used for the metallurgical processing of ilmenite into synthentic rutile, which is high in titanium. Scope 1 emissions at our Sierra Rutile operation are largely related to the use of diesel in vehicles and the power station for the generation of electricity. The power station consists of four engine driven generators with marine fuel oil as a fuel source and operates all year to supply electricity to the operations. 
 

[1] Scope 1 greenhouse gas emissions are the emissions released to the atmosphere as a direct result of an activity, or series of activities at a facility level.

[2] Scope 2 greenhouse gas emissions are the emissions released to the atmosphere from the indirect consumption of an energy commodity. For example, ‘indirect emissions’ come from the use of electricity produced by the burning of coal in another facility. Scope 2 emissions from one facility are part of the Scope 1 emissions from another facility.
