Our Approach

Managing energy consumption and greenhouse gas (GHG) emissions is a high priority for Evolution as we continue to focus on our climate-related risks and opportunities. We monitor transition risk in relation to energy and emissions regulations through climate policy advocacy with a proactive approach to resource efficiency and energy planning.

When measuring our emissions performance Evolution applies a location-based method, which reflects the average emissions intensity of grids on which energy consumption occurs. Detailed monthly capture and analysis of our energy and emissions performance is conducted in alignment with the Evolution Sustainability Performance Standards.

Our Net Zero commitment was based on the baseline data derived from an aggregate of all Evolution assets’ emissions profile in FY20. The baseline has since been recalculated due to the divestment of Cracow and acquisition of Red Lake. This adjustment is reflected below in our emissions performance.

Operations are proactively engaged in achieving our medium term and long-term emissions targets through understanding their carbon footprint, developing industry partnerships and investigating technology pathways as outlined in the ‘Climate
Risk’ section.

We take a long-term view of emissions reduction with the first milestone commitment of 30% reduction in CO2-e by 2030 (FY20 baseline). With this understanding Evolution acknowledges that our journey will require sustainable operations focussing on periods of development and construction paired with wholesale change in the process introduced though the technology pathway program

Our Performance

Our FY21 emissions performance compared to FY20 is as per below:

GHG Emissions FY21 FY20 (actual baseline) % change FY20 (adjusted baseline)* % change
Greenhouse gas emissions Scope 1 (t CO2-e)
178,395
157,857

Greenhouse gas emissions Scope 2 (t CO2-e)

* Adjusted FY20 emissions baseline to include current assets and exclude divested asset (Cracow).

In FY21, Evolution’s direct emissions (Scope 1) and indirect emissions (Scope 2) were 549,484 tonnes of CO2-e with Scope 2 emissions accounting for 68% of the total emissions during the year.

Compared to FY20, Scope 2 emissions reduced by 7% as total renewable energy purchased increased by 148 million kWh compared to the previous year. This is attributed to Red Lake where over 70% of their energy comes from renewable sources.

Compared to FY20, Scope 2 emissions reduced by 7% as total renewable energy purchased increased by 148 million kWh compared to the previous year. This is attributed to Red Lake where over 70% of their energy comes from renewable sources.

Scope 2 emissions reflect two thirds of emissions, with our Cowal operations in NSW contributing almost half of all emissions. There will be an increased focus in FY22 on efficiencies improvement plans, looking to integrate solutions where they will have the most impact. Whilst there has been an increase in Scope 1 emissions of 21% due to increased trucking, haulage and diesel consumption, efficiencies were delivered with a decrease in Scope 2 emissions (electricity) of 4%. There was a 10% increase in utilisation of truck fleet between FY20 and FY21, in addition to four additional haul trucks (new hires) added to the fleet in January / February 2021. The number of truck cycles increased 31%, with average haul distance increasing from 9.7km to 12.1km with Stage 2 IWL works. This contributed to an increase in ore and waste mined (29% and 5% respectively). This equated to a 65% increase in haulage distance for the truck fleet between FY20 and FY21 due to the development of the underground decline.

Emissions Intensity

Our FY21 emissions intensity performance compared to FY20 is presented below.

Emissions Intensity (CO2-e) FY21 FY20 (actual baseline) % change FY20 – (adjusted baseline)* % change
Emissions intensity per tonne material mined (t Scope 1 and Scope 2 CO2-e/tonne)
0.0129
0.0132

0.0126

Emissions intensity per tonne ore processed (t Scope 1 and Scope 2 CO2-e/tonne)

Emissions intensity by gold produced (t Scope 1 and Scope 2 CO2-e/ounce)

* Adjusted FY20 emissions baseline to include current assets and exclude divested asset (Cracow).

A FY21 target was to establish a stronger baseline target for an emission intensity per tonne of material mined. The target of 0.012t CO2-e was established. The performance of 0.0129 CO2-e was within the target range.

Emissions intensity of 5% increase per gold produced was due to the processing of lower grade ore. Evolution processed 1% more tonnes in FY21 to produce 14% fewer ounces. This was predominantly due to the processing of low-grade stockpiles whilst mine development continued ensuring the sustainability of all operations.
