Since the beginning of ICAO's journey to progress in terms of policy development and standards setting to limit and reduce the impact of aviation on the global climate, ICAO Member States demonstrated that they were interested in taking action and advancing initiatives on environmental protection. However, not all of them had the human, technical and financial resources to do so. To overcome this challenge, ICAO launched the State Action Plan initiative in 2010 as a means to provide States with the capacity and tools to take action.

This initiative enables all ICAO Member States to establish a long-term strategy on climate change for the international aviation sector, involving all interested parties at national level. These parties are encouraged to work together to define a quantified baseline scenario, select appropriate emissions mitigation measures from ICAO's basket of measures, and calculate the expected results of implementing those measures. The level of detail submitted within a State Action Plan will ultimately enable ICAO to compile global progress towards meeting the goals set by Assembly Resolution A37-19, and reaffirmed by A38-18, A39-2, A40-18, and A41-21. States are invited to update their State Action Plans every three years, so that ICAO can continue to compile the quantified information submitted.

In order to support its 193 Member States with the development of their State Action Plans, ICAO has developed Guidance on the Development of States' Action Plan on CO2 Emissions Reduction Activities (Doc 9988), which provides a detailed step-by-step approach to develop a State Action Plan and meet the basic requirements. In addition to a series of guidance documents, ICAO provides States with the necessary quantification tools. More information about these resources is available from the State Action Plans – Frequently Asked Questions  page, under the question, "How can ICAO help in the development of a State Action Plan on CO₂ Emissions Reduction Activities?" Additionally, in order to ensure that resources would be available to States for the development of their action plan, ICAO successfully established two partnerships with international organizations to secure funding for the development of specific technical assistance projects in support of its Member States' actions to reduce aviation emissions. These projects started in 2014 and were implemented by ICAO with great accomplishments. More information on these projects is available from the dedicated Capacity Building and Assistance page.

The table below provides an overview of all States that have submitted and/or updated a State Action Plan to ICAO on CO₂ Emissions Reduction Activities for international aviation to date. All State Action Plans are considered confidential, unless the State grants specific permission to share their State Action Plan publically. Where States have decided to make their Action Plan publicly available, a hyperlink is provided directly linking to the document.
