State Action Plans

At its 38th Assembly, ICAO reminded States to submit or update their 'State Action Plans' (Action Plan on Emissions Reduction) as a practical means to communicate to ICAO information on their activities to address CO2 emissions from international civil aviation.


The invitation to ICAO Member States to voluntarily submit their Action Plans on Emissions Reduction (APER) to reduce CO2 emissions from international civil aviation to ICAO originates from the 37th Session of the ICAO Assembly in October 2010.

The main objective of the APER is to allow States to showcase the specific voluntary measures they intend to take in order to improve efficiency and thereby contribute to the global environmental aspirational goals established by ICAO.

The level of detail of the information contained in an APER must demonstrate the effectiveness of actions and will ultimately enable ICAO to measure global progress towards meeting the goals.

ICAO 38th Assembly

The resolution refers frequently to the submission of APERs. ICAO said that around 70 Member States, representing approximately 80% of global international air traffic, had prepared and submitted their APER to ICAO. It was then expected that the submission of additional action plans by the end of 2013 would bring the total coverage of global international air traffic to over 90%.

ICAO also further encourages States to submit their APER outlining their respective policies and actions, and annual reporting on international aviation CO2 emissions to ICAO. 

ICAO invites those States that choose to prepare or update their APER to submit them to ICAO as soon as possible, preferably by the end of June 2015 and once every three years thereafter, so that ICAO can continue to compile the information to achieve the global aspirational goals.

The APER should include information on the basket of measures considered by States, reflecting their respective national capacities and circumstances, information on the expected environmental benefits from the implementation of the measures chosen from the basket, and information on any specific assistance needs.

ICAO also encourages States that have already submitted their APER to share information contained in their plans and build partnerships with other States in order to support those States that have not prepared their action plans.

Finally, ICAO requests the Council to facilitate the dissemination of economic and technical studies and best practices related to aspirational goals and to continue to provide guidance and other technical assistance for the preparation and update of States’ action plans prior to the end of June 2015, for States to conduct their necessary studies and to voluntarily submit their action plans to ICAO.

Content of an APER

At a minimum the following information is contained in the plan:
  • Contact information
  • Expected results: International RTK (Revenue Tonne Kilometre), fuel consumption, and projected future CO2 emissions (to 2050 is ideal)
  • List of measures proposed to address CO2 emissions from international civil aviation
  • Information on any assistance needs (financial, technological, training, etc.)
