Technical Information

The « weighted measure-based overall » indicator (called IGMP for “Indicateur Global Mesuré Pondéré”) represents the noise energy at Paris-Charles-de-Gaulle airport. Defined by a decree dated on January 28th 2003, it restricts for each year the overall amount of noise energy emitted by aircraft activity at the airport.

IGMP is calculated since 2007 by the Technical Civil Aviation Centre (STAC), from noise measurements carried out continuously over a year by ADP (“Aéroports de Paris”). Each year, this indicator statement is submitted to the Independent Airport Nuisance Control Authority (ACNUSA), and is finally forwarded to Environment Advisory Committee.

This document introduces IGMP’s principles and terms to the method of calculation.
