Smart environmental standards

EASA develops smart environmental standards with its international partners to ensure that state-of-the-art noise and emission reduction technologies are integrated into aircraft and engine designs.

In this context, smart standards achieve their environmental objectives at minimal costs. EASA actively contributes to the ICAO Committee on Aviation Environmental Protection (CAEP) which develops and maintains the international standards for aircraft noise, aeroplane CO2 emissions, fuel venting and aircraft engine emissions: oxides of nitrogen (NOx), unburned hydrocarbons (HC), carbon monoxide (CO), smoke and non-volatile particulate matter (nvPM). Once the standards have been agreed in ICAO, EASA works with the European Commission to implement them into EU legislation by amending the corresponding rules. Environmental standards are currently reflected in Article 6 of the Basic Regulation, Annex I (Part-21) of the Implementing Regulation, and the Certification Specifications of CS-34 (emissions) and CS-36 (noise). EASA is also involved in standardisation committees working on technical specifications which support the ICAO standards (e.g. SAE, ISO).
