Air emissions intensity of manufacturing

This indicator measures the emissions intensity of particulate matter (PM10 and PM2.5) from the manufacturing sector (NACE Rev. 2 sector ‘C’). Air emissions are defined as flows of gaseous and particulate materials emitted into the atmosphere. Fine and coarse particulates (PM10) are less than 10 micrometres in diameter and can be carried deep into the lungs, where they can cause inflammation and exacerbate the condition of people suffering from heart and lung diseases. Fine particulates (PM2.5) are less than 2.5 micrometres in diameter and are therefore a subset of the PM10 particles. Their negative health impacts are more serious than PM10 because they can be drawn further into the lungs and may be more toxic. Emission intensity is calculated by dividing the sector’s PM emissions by its gross value added (GVA), which is defined as output (at basic prices) minus intermediate consumption (at purchaser prices).
