ICAO Airplane CO2 Certification Database

The International Civil Aviation Organization’s (ICAO) Airplane CO2 Certification Database (CO2DB) contains information on airplane CO2 emissions, determined according to the procedures in ICAO Annex 16, Volume III, and where noted, certified by the States of Design of the airplanes according to their national regulations. 

The CO2DB covers new airplane type designs from 2020, and airplane type designs already in-production as of 2023. Those in-production airplanes which by 2028 do not meet the standard will no longer be able to be produced unless their designs are sufficiently modified to comply with the in-production standard. In accordance with Annex 16 Volume III, the CO2DB covers subsonic jet airplanes over 5,700 kg and propeller-driven airplanes over 8,618 kg.

The information is provided by the Certification Authority of State of Design or airplane manufacturers, who are solely responsible for its accuracy. The U.S. Federal Aviation Administration (FAA) is hosting the CO2DB on behalf of ICAO and is not responsible for the contents.

The objective of the CO2DB is to:

  1. Provide publicly available data on the CO2 metric value (MV) which represents an indication of CO2 emissions performance of airplane types against CO2 technology/design standards.
  2. Track and communicate the improvement in airplane CO2 MVs over time.
  3. Provide an incentive to improve the CO2 MV of airplane types.

Airplane manufacturers submit their data to the primary Certification Authority of State of Design (CA) for approval as part of the certification process. Once the data has been approved by the primary CA, the airplane manufacturers confirm the voluntary decision to submit the data to the U.S. FAA. The CA voluntarily submits it to the U.S. FAA Office of Environment and Energy via email at 9-AWA-CO2BD@faa.gov for inclusion in the CO2DB. The data must be submitted in a predefined format (see Excel data template in the below Downloads section). The primary CA verifies that the data submitted to the CO2DB is in conformity with the approved data from certification. The U.S. FAA then checks the data format and consistency before publishing it. The frequency of databank updates depends on the availability of new data.
