Our coal is lower in emissions Demand for high quality, high-CV, low ash coal is increasing in efforts to reduce CO2-e emissions Whitehaven's thermal coal is used in high-efficiency, low emissions (HELE) electricity generation including Ultrasupercritical (USC) power plants Whitehaven's coal allows USC power plants in Asia to deliver -27% lower emissions than typical sub-critical plants in Asia using lower quality coal In customer countries of Japan, Korea, Taiwan and Malaysia, 46% of coal fired power capacity (GW) is from USC plants compared with 20% 20 years ago Japan and Korea are commissioning 7 new USC units (totalling 5,970MW) (2022-24) tCO2/MWh Coal-fired power plants - GHG emissions per MWh sent out¹ 1.29 0.89 42% Key Power plant 11% 22% 27% Sub-C type / specs Subcritical 16-18 Mpa, <540°C SC 1.02 1.02 0.91 0.90 0.87 USC 0.80 0.75 Typical Aus.
