Climate change

Climate change is the long-term shift in the Earth’s climate conditions. It originates from natural factors, but today it is accelerating mainly because of greenhouse gas (GHG) emissions linked to human activity. The rising concentration of CO2 and, to an even...

Stack emissions

Stack emissions are gases and particles released into the atmosphere through chimneys, ducts or outlets of stationary industrial sources, such as power plants, refineries, cement works, chemical plants and incinerators. They are measured through periodic stack tests...

Nitrogen oxides (NOx)

Nitrogen oxides (NOx) and nitrous oxide (N2O) are key air pollutants affecting air quality and climate across multiple sectors: urban, industrial and agricultural. Generated by vehicle combustion, industrial processes and nitrogen fertilisation, these gases contribute...

LDAR (Leak Detection and Repair)

LDAR programmes are technical plans for detecting and repairing industrial fugitive emissions that allow operators to locate, measure, prioritise and correct emissions of gases, vapours or volatile compounds from facilities. Their effectiveness depends on how...

Nitric oxide (NO)

Nitric oxide (NO) is one of the most important, and often underestimated, gases in the field of air quality and industrial emissions management. Colourless, odourless and highly reactive, NO belongs to the group of nitrogen oxides (NOx), compounds directly linked to...
