Coal power toxic emissions spiked even as energy output dropped

Last legs. Liddell power station remains the state's largest emitter of PM2.5 particle pollution.

The latest national pollution data shows several Hunter and Central Coast power stations have reported significant increases in toxic emissions while overall power generation dropped.

Despite a 31 per cent and 9 per cent drop in generation at Liddell and Bayswater respectively, both pumped more pollution into the air in 2020-21 than the year prior, according to new National Pollution Inventory data.
