A CALL FOR AN ENVIRONMENTALLY RESPONSIBLE AVIATION

Seen 1027 times

We, alumni and students of ENAC (National University of Civil Aviation), are fully aware of the externalities of civil aviation, both positive and negative, that affect the environment and our society.

The value of air transportation to the world is undeniable. In many cases, no other mode of transportation can replace the unique type of mobility it provides.

Air transportation brings people together and promote fraternity, which are essential for maintaining world peace. It is a vector of cultural and economic development, and it promotes social and political integration as it facilitates connections between countries and regions, as well as their economies and populations.

Essential to the economy, employment, and tourism, air transportation is also a tool for the development and the accessibility of communities. Among other things, it maintains a link with overseas and landlocked territories.

Aircraft serves everyone, carrying out medical evacuations, delivering time-sensitive medical personnel and equipment as well as emergency supplies, and performing urgent and perilous rescue operations, both on a daily basis and during crises, especially when the ground infrastructure is unserviceable.

While we consider that air transportation will remain essential in this respect, we believe also that cooperation and partnerships between the various stakeholders of this sector, and beyond, will make it possible to find and implement relevant solutions to maintain and increase the efficiency of aviation. We pledge to contribute to this effort through our collective and individual activities.

Aviation still needs to optimize its environmental footprint.

Like the vast majority of human activities, aviation generates pollutions locally (noise, adverse impact on air quality, footprint of facilities, etc.) and contributes to climate change. 

The aviation sector came to that realization as early as the 1970s and 1980s, when the first environmental standards were established by the International Civil Aviation Organization (ICAO), the United Nations agency dedicated to civil aviation.

Research programs have ever since identified technological improvements and clarified certain impacts(1). International norms and standards have made it possible to promote and support the implementation of technological improvements throughout the global aircraft fleet regarding noise(2), air quality(3), and greenhouse gas emissions(4). The aviation industry has been able to reduce its environmental impact, including on climate, thanks to these technological and operational innovations.

With a reduction of fuel consumption per passenger and per kilometer of about 80% over the last five decades, aviation currently contributes to 2% of anthropogenic CO2 emissions. According to the latest studies selected by the IPCC(5), if we take into account other emissions (NOx, water, etc.) and their potential warming effect, the overall impact of aviation is estimated to reach 3.5% of the global radiative forcing. However, the IPCC also mentions uncertainties on these figures(6).

Aviation was the first economic sector to create a worldwide carbon offsetting system(7). Also, aviation has voluntarily committed to "Net Zero Emission".

It must now accelerate the implementation of technological and operational improvements with disruptive solutions such as the expansion of the sustainable alternative fuel production, the optimization of airspace utilization, the design of new aircraft geometries, and the development of new propulsion systems based on electric, hybrid-electric, or hydrogen technologies.

The aviation industry must keep its commitment to achieve net zero emission, and it must reinvent itself to recover from an unprecedented health and economic crisis.

Fully engaged in addressing these issues – that can be divisive, we call for a balanced, fact-based, and quantified approach that would guide technological progress and practices towards an air transportation that reinvents itself with the shared goal of preserving Earth – our common home.

Consequently, we pledge to:

  1. Increase the environmental aspects of our scientific skills, from the time of our initial education and throughout our careers;
  2. Raise awareness on environmental issues within our organizations, education institutions, and to our colleagues;
  3. Promote the innovation capability of the aviation industry in order to keep attracting the best talents and ensure its sustainability;
  4. Guide our choices in our professional activities according to a balanced approach integrating environmental and sustainable development criteria;
  5. Develop and implement the best technologies and practices with regard to the environment, in our various fields;
  6. Promote the emergence of new sustainable air mobility, of all forms, in order to revive the unifying and innovative spirit of the aviation adventure of which France is the cradle – along with other nations, and to perpetuate its technological and operational excellence.

We want to work on further improving our knowledge and cooperate with scientific experts to reduce existing uncertainties. We want to research scalable and disruptive solutions that will help aviation meet present and future needs, and contribute to the United Nations’ Sustainable Development Goals (SDGs).

ENAC Alumni is the association of all the alumni of ENAC. With over 26,750 members worldwide, the goal of the association is to organize this community through chapters all around the world, think thanks, Women of ENAC (Les Elles de l'ENAC), and above all its many volunteers who contribute effectively to the influence of the university.

ENAC, the National University of Civil Aviation, is a university of the French Civil Aviation Authority (DGAC), a directorate of the Ministry of Ecological Transition. It brings together educational and research activities in aeronautical engineering, air navigation, and piloting.
Each year, ENAC welcomes more than 2,000 students through more than 30 programs, as well as 3,500 professionals in continuing education.
As proof of its international influence, over 26,750 former students are based in more than a hundred countries on all five continents. Thanks to its size and its human and educational resources, ENAC is today the leading European aeronautical school.

(1) Research programs including MOZAIC and IAGOS have shown that nitrogen oxide (NOx) emissions from subsonic air traffic do not contribute to the destruction of the ozone layer. However, at these altitudes, these emissions contribute to ozone formation and methane destruction.
(2) Noise: Aviation has reduced and continues to reduce its noise footprint through continuous technological improvements and increasingly stringent standards. Note (*): 34 EPNdB difference between the Chapter 2 standard established in 1972, and whose aircraft have been banned in Europe since 2000, and the latest Chapter 14 standard that all aircraft models must comply with since 2018. These standards are detailed in Volume I of ICAO Annex 16.
(3) Air quality: The aviation industry adopts high certification standards in terms of air quality, for certain pollutants such as nitrogen oxides (see Annex 16, Volume II, the first standard of which was established as early as 1981); it also adapts its operational practices locally (e.g., use of electric 400Hz power units instead of the APU).
(4) A certification standard for CO2 was also introduced in 2017, applicable starting 2020. It is the subject of Volume III of ICAO Annex 16.
