ED Decision 2025/016/R
APPLICABLE ENGINE EXHAUST EMISSIONS REQUIREMENTS
This determination is made according to the data provided by the engine type-certificate holder. It should be noted that the competent authority has the possibility to grant exemptions from these requirements as noted in Chapter 2, paragraph 2.1.1 and Chapter 4, paragraph 4.1.1 of Part III of Volume II of Annex 16 to the Chicago Convention.
When such an exemption is granted, the competent authority:
â takes into account the number of exempted engines that will be produced and their impact on the environment;
â considers imposing a time limit on the production of such engines; and
â issues an exemption document.
ICAO Doc 9501 âEnvironmental Technical Manualâ Volume II provides guidance on the issuing of exemptions.
