United States Submits Six Working Papers to CAEP/12 Meeting

ICAO’s Committee on Aviation Environmental Protection (CAEP) will meet for its twelfth triennial meeting in February 2022. Consistent with the Biden-Harris administration’s commitments to addressing the climate challenge and tackling environmental issues, the United States submitted six working papers seeking increased climate and environmental ambition in the committee’s work for the next three years.

The six papers cover a number of topics and are available below.

WP/59 – Views of the United States on the Feasibility of a Long-Term Aspirational Goal for International Civil Aviation CO2 Emissions Reductions (PDF 267 KB)

  • This paper presents the views of the United States on the CAEP LTAG-Task Group (LTAG-TG) analyses and recommendation. It also places the results of the LTAG-TG in context of the 2021 U.S. Climate Action Plan that describes the efforts of the United States to reduce CO2 emissions from aviation by 2050.

WP/60 – Views of the United States and Recommendations on the WG4 Work Programme (PDF  261 KB)

  • This Working Paper provides the U.S. views on the final recommendations of WG4. This paper also highlights the needs for continuing technical work related to CORSIA from WG4 and provides feedback for efficiencies to improve WG4’s effectiveness in next CAEP cycle.

WP/61 – Views of the United States on Future Work in the CAEP/13 Cycle (PDF 156 KB)

  • This paper presents the views of the United States on several “CAEP-wide” items for CAEP’s consideration. In particular, the paper highlights the need to prioritize CAEP tasks and increase transparency within CAEP. In addition, specific future work tasks suggested by the United Sates are captured in individual papers.

WP/62 – Views of the United States on Emissions Future Work During the CAEP/13 Cycle (PDF 227 KB)

  • This paper presents the views of the United States on emissions future work items for the CAEP/13 work program. The paper includes proposals for the integrated development of more stringent aeroplane CO2 emissions and noise standards, as well as for the development of a new NOx metric system and more stringent engine NOx and nvPM standards. The appendix provides the completed CAEP’s Future Work Item forms that cover the proposals in the paper.

WP/63 – Views of the United States on Future Work Related to Emerging Technology Aircraft (PDF 153 KB)

  • This paper presents the views of the United States on Future Work related to Emerging Technology Aircraft (ETA). The United States notes increasing interest in ETA and highlights ongoing domestic activities regarding ETA. The United States supports the WG1 future work proposal regarding ETA.

WP/64 – Views of the United States on Supersonic Aircraft Noise Future Work During the CAEP/13 Cycle (PDF 148 KB)

  • This paper presents the views of the United States on the supersonic work within the CAEP and, in particular, ongoing technical discussions in Working Group 1 (WG1) on noise. The United States is committed to advancing the development of supersonic aircraft, as part of our broader efforts to support innovation in transportation and infrastructure. The United States supports the WG1 proposal to develop a supersonic LTO Noise SARP during CAEP/13 based on Chapter 14 limits and continued work on a supersonic en route noise SARP.

CAEP is a technical committee of the ICAO Council established in 1983. CAEP assists the Council in formulating new policies and adopting new Standards and Recommended Practices (SARPs) related to aircraft noise and emissions, and more generally to aviation environmental impact.

CAEP undertakes specific studies, as requested by the Council. Its scope of activities encompasses noise, local air quality (LAQ) and the basket of measures for reducing international aviation CO2 emissions, including aircraft technology, operational improvement, sustainable aviation fuels and market-based measures (CORSIA).

CAEP informs the Council’s and Assembly’s decision making with the ICAO Global Environmental Trends, which assess the present and future impact of aircraft noise and aircraft engine emissions. The Global Environmental Trends is crucial to the work of ICAO as it provides a robust single reference for sound discussion and decision-making.

The Council reviews and adopts CAEP recommendations, including amendments to the SARPs, and in turn reports to the ICAO Assembly where the main policies on environmental protection are ultimately defined.
