A system to allow residents to measure plane noise & track flight paths

Our last webinar was on 17th July.

EANS is a pure form of citizen science is developed by Frankfurt residents, and is now used by communities at over 50 airports worldwide.

Talking About Noise

The Dutch government tries again and again to put people to sleep that it is not too bad with that aircraft noise and that if you do experience nuisance, it will soon be a lot less. Firstly, it is not easy at all and secondly, the nuisance will not diminish quickly. Minister Harbers wants the airport to be able to grow indefinitely from 2027 thanks to the quieter aircraft.

Prof. Dr. Fulco van der Veen on noise violence.

On International Noise Awareness Day, this year on April 26th, and during the two weeks following it, local communities have staged activities to call for a limit, a cap, on flight numbers and airports. It was an initiative of UECNA.

Here are the reasons we were doing it:

  • Aviation has yet to reduce its impact on communities living near airports (and on the climate). Noise and air pollution significantly harm people’s health and there are few signs of meaningful reductions.
  • There are signs the aviation industry will reduce its climate impact on the planet by 2050 through the introduction of new technology and sustainable fuels but this is not the case with local pollutants. There cannot be unlimited growth while these problems remain. Growth must be limited.  At least until a solution is found for all forms of pollution. We, citizens, cannot suffer more noise and more toxic air
  • Caps must be put at all airports to limit aircraft movements, to limit air pollution, to limit noise pollution, to limit climate impact.


Here you’ll find the results!


One of our videos:

The Dutch administration aimed to reduce the number of flights from 500 to 440 thousand due to too much aircraft noise. And Schiphol’s new interim CEO came up with the decision to abolish night flights (between 0.00 and 5.00 hours), cancel the option for a new runway and ban private aircraft.

How will this work out?

Missed Targets of the Aviation Industry

Two decades of missed and abandoned aviation industry sustainability targets: they appear to function principally as a tactic for giving an impression of progress and action to address aviation’s environmental impacts to the public and policymakers, in order to prevent any policy barriers to ongoing growth in the industry. A short video (with subtitles) and the report from Possible.

Results so far (13/9):
1 Noise nuisances : 22% |  2 Health effect : 16%  |  3 Reduce the number of flights : 13%  |  4  Ban on night flights : 12%  |  5     Emissions :  10%  |  6  Taxes :  7%   |  7/8  International cooperation  /  Influence the EU :  4%  |  9/10  Getting stronger as an organization / Ban on short-haul flights : 3%

A Voice against Noise and for Health:

Air transport and airport-related activities are responsible for noise pollution and emission of toxic pollutants. The noise – especially at night – and the pollutants have both proven to have serious adverse effects on human health. In particular causing high blood pressure leading to cardiovascular diseases and death.

Our health is precious and needs respect and protection.

All stakeholders, ie. operators of airports, air carriers and aircraft builders, but also aviation administrations and politicians, must take into consideration the populations who suffer from the impact of air traffic. Today, the aviation lobby is so powerful that is it very difficult for the population living under flight paths to be heard.

We want to provide a voice for residents living in the vicinity of airports across Europe

Because airports are in competition with one another, any restrictions applicable to one airport will be considered a disadvantage when compared to other airports. Therefore, restrictions will only be accepted if they are applied to all airports. We want to work with the European commission and the European Parliamentarians to ensure that residents living under flight paths have a voice.

The future of all of our airports must be decided at European level.

Why donate?

UECNA stands for Limiting the Impact of Aviation. This Europe-wide organization represents everyone affected by aircraft health loss. That’s you too, because planes fly above all of us. With emissions and noise that negatively affect your lifespan and that of your (grand)children. We want the International Civil Aviation Organization (ICAO) to abolish Article 44 which continues to promote that aviation is good for the future of humanity. So support us, because every euro counts to counterbalance the aviation lobby.

Be part of UECNA, the umbrella citizens organisation which represents airport communities at the European Parliament, the European Commission and ICAO. It also supports organisations and citizens with expert advice and by exchanging information, experience and best practices.

Aviation and the Power of ICAO

The Netherlands wants to reduce the number of flights to and from Schiphol Airport because of the noise nuisance for local residents. But is that possible? In this video we wonder whether this will work based on noise arguments, while keeping an eye on goat paths for when the main road is blocked.

Taking action can help

On our Actions page you’ll find a lot of examples

And there is room enough for new ideas.

Various actors that can stimulate the reduction of nuisances: residents (R), organisations of residents (O), scientists (S), political parties (P), municipalities (M), governments (G), European members of parliament (E), celebrities (C) and UECNA (U).

Who We Are:

UECNA is an independent organisation aiming at protecting population under planes flight paths.

The ever increasing air traffic causes serious noise and air pollutions which have adverse health impacts on the populations overflown by aircraft at low altitude The number of people affected by these pollutions is also increasing despite the European legislation and improvement in technologies.

Communities near airports are also deeply concerned about the rise in CO2 and non-CO2 emissions from aviation, which are a threat to the climate.

If the growth of aviation is not severely constrained, air traffic will largely negate the effects of national efforts to reduce CO2 emissions. Residents’ organizations all over Europe believe that the growth of aviation must be limited.

UECNA summons the EU:

  • Noise: to ensure a substantial reduction in noise nuisances caused by aviation, starting with a reduction of night flights with a view to a total ban on night flights to allow an 8-hour night;
  • Air pollution: to reduce emissions from aviation (including UFP) to protect the health of people living under flights paths and near airports, and to prevent further environmental degradation;
  • Climate: to force airlines, like all companies, to reduce their CO2 emissions in the context of the Paris Agreement;
  • Sustainable travel: to levy taxes on air tickets and jet fuel and to enhance comfortable train connections at competitive prices, so that many short European flights can be cancelled.
