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 unmanned aircraft, including remotely piloted aircraft and urban air mobility concepts. 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.
