CAEP/10 was the first time that recommendations for two emissions standards were able to be finalized, paving the way for cleaner aircraft that have less impact on the global climate. An important Particulate Matter (ultrafine soot particles) Standard was one of these, while the second was the much awaited aircraft CO2 emissions design Standard, the first global Standard for CO2 emissions for any sector.
The CAEP reviewed a vast amount of technical work related to a global market-based measure for international aviation emissions. This will provide a solid basis for the discussions and expected adoption of the aviation MBM design scheme at the 39th ICAO Assembly this fall. If adopted, the aviation MBM is expected to be slated for implementation by 2020.
Sustainable alternative fuels
An impressive amount of work on the sustainability criteria and life-cycle analysis for sustainable alternative fuels was carried out. Developments in this area will be paramount for the sustainable future of aviation and the CAEP’s life-cycle analysis conclusions will serve as an important market indicator supporting higher production and use of alternative fuels in the future.
A methodology to quantify air cargo CO2 emissions was also approved. This complements the ICAO carbon calculator for passenger air travel emissions and is our new contribution to the UNEMG.
New guidance on community engagement in aid of more inclusive aviation environmental management and airport planning, including for adaptation to climate change, is expected to be of direct assistance to States.
Updated projections for aircraft noise and emissions were approved. These will be recommended as the basis for decision-making for matters related to the environment during the upcoming ICAO Assembly later this year. Future work will include putting these trends into context of a 2°C emissions budget scenario.
For the first time, ICAO and its Member States will be able to consider the possibility of “noise neutral growth” from 2030 under an advanced technology and operational improvements scenario.
