The airport performs air quality control tests in two huts equipped to measure and register atmospheric pollutants.
The airport's Environment Department monitors the atmospheric pollution levels in emissions. To do this, it has 4 stations for measuring atmospheric pollution and controlling air quality. These stations automatically measure the concentrations of the following pollutants: carbon monoxide, sulphur dioxide, nitrogen monoxide and dioxide, ozone and volatile organic compounds. It also carries out campaigns of manual particle measurements (PM10, lead and PM2.5) and benzene. Additionally, each station is equipped with a meteorological station. The stations are located in the airport and in strategic points in the surrounding area (in Gava, El Prat and Viladecans). Those located outside the airport facilities form part of the Catalonian Government Environmental Control Surveillance Network from where the measurements can be viewed.
As regards emissions, the airport controls emissions produced in focal points of equipment and installations: Natural gas boilers for heating, emergency electrogenous equipment in power plant: CELT, CELA, CENAT; vehicles; condenser gases (potential) of cooling equipment and firefighting protection equipment.
The airport encourages responsible use of the installations and equipment that emit pollutants into the atmosphere and carries out the emission reduction programmes applicable to the airport in the current environmental regulations (such as the programme for the actions to reduce the emissions of nitrogen oxide (NOx) and particles (PM10), derived from the Environmental Impact Statement (EIS) for the extension of the airport and Decrees 226/2006 and 152/2007 dictated by the Catalonian government, addressed to improving the environmental air quality in the municipalities of the Baix Llobregat).
Some of the most significant measures are:
- Optimisation of the use of the aircraft's auxiliary power units (APUs).
- Progressive substitution of vehicles that use fossil fuels for electrical vehicles.
- Optimisation of aircraft land movement operations.
