Data may differ from Sustainability Report FY2021 as an enhanced calculation methodology has been adopted in FY2022. 2. Aggregated data from our midstream (PMBtu, PMS, PMAR) and downstream (PMBA, PMI, PMIT) facilities. 3. Scope 1 includes direct GHG emissions from facilities owned or controlled, and includes fuel use, anode and reductant use, and process GHG emissions. Scope 1 and Scope 2 GHG Emissions In FY2022, our total operational GHG emissions (Scope 1 and Scope 2) amounted to 3,227.5 KtCO2-eq, representing a 6.7% increase from the preceding year, mainly due to the increased production capacity from the fully-commissioned Phase 3 plant in PMBtu, from 640,000 tonnes to 960,000 tonnes per annum. GHG emissions intensity was recorded at 2.6 tCO2-eq/ tonne of aluminium produced, a 7.1% decrease compared to FY2021 due to the optimisation of manufacturing processes. However, GHG emissions intensity in FY2022 remained elevated at 8.3% from the 2020 baseline due to operational issues arising from delays in relining of ageing pots, anode effects, and airburn.
