The ICAO CO 2 emissions standard was made 10% more stringent today and is applicable to new aircraft type designs as of 2031. ICAO is now beginning preparations for a potential return of supersonic aircraft by addressing their noise impact first. ICAO strengthens global framework for accident investigations: New global standards will ensure aircraft accident investigations are not halted or compromised by conflicts of interest, following the landmark decision by the Council of the International Civil Aviation Organization (ICAO). It is in response to these concerns that ICAO has decided to update the standards in Annex 13. The Council also approved changes clarifying that accident investigation authorities must have unrestricted access to all evidential material without delay, to prevent misinterpretation by authorities regarding allowing restrictions on access.
