New innovative technologies and energy sources for aviation are under development in a fast pace, and ICAO is closely following up these developments to prepare for their timely environmental certification, as appropriate. In that regard, ICAO is maintaining the E-HAPI, a website with a non-extensive list of ongoing projects that have been identified globally.
Specifically on aircraft noise, ICAO is following up possible environmental issues from the operation of Emerging Technology Aircraft (ETA), including urban air mobility concepts, unmanned aircraft and remotely piloted aircraft. States and Stakeholders are invited to contact us at email@example.com and share experiences in responding to these aircraft noise issues. This information will be consolidated as a potential best practice guidance for States.

Brazil - ANAC published an UAS regulatory roadmap, which foresees the discussion of noise requirements in 2023-2024.
EASA - EASA is addressing noise requirements for UAM and Drone manufacturers on an individual basis until a general noise requirement scheme is available. Guidelines for the measurement of UAS noise are currently being developed and should be published for consultation in the last quarter of 2022.
ICCAIA - Manufacturers
have recognized the need to design products substantially more quiet than
current conventional helicopters, and are supporting the development of ETA
noise certification procedures at CAEP.
