Validation of sulphur dioxide measurement methods will lay the foundation for future-proof emissions monitoring

Sulphur dioxide, emitted during the combustion of solid fuels, has long been recognised as a pollutant which can have adverse effects on human health, aquatic ecosystems in rivers and lakes, and forests, crops and other vegetation. Recognising the large economic and societal burden, the EU places increasingly stringent limits on emissions of sulphur dioxide through the Industrial Emissions Directive (IED), which is projected to prevent 13 000 premature deaths and 125 000 years of life lost. Successful implementation of the IED relies on an underpinning measurement capability which enables regulators to enforce it. However, existing Standard Reference Methods (SRMs) for the measurement of sulphur dioxide emissions are no longer fit for purpose at the low levels permitted by the latest iteration of the IED. This project will test the performance of existing and alternative SRMs, in both the lab and the field, putting in place the foundation needed to develop a new SRM for robust regulatory monitoring of sulphur dioxide emissions from industrial processes.
