Toxic emissions from some coal-fired power stations have risen even though they are generating less electricity than in the past, according to an analysis of National Pollutant Inventory data.
The NSW government will amend state regulations with the aim of improving the quality of National Pollutant Inventory data it receives from hundreds of companies.
Legal activist group Environmental Justice Australia says new NPI data on particle pollution should trigger an EPA investigation into Delta Electricity, and confirm its view that dust controls at Yallourn power station are faulty.
This year's National Pollutant Inventory data has provided evidence that widely-used emission estimation manuals are seriously flawed, according to an expert on the scheme.
The Turnbull government's 2018 environmental agenda will affect importers of new chemicals, companies required to report pollutant emissions, suppliers of products that lead to problem wastes, and facilities that emit large quantities of greenhouse gas.
New National Pollutant Inventory data shows that either some industries have seen radical changes in their emissions or the scheme's quality control is poor.
