More than once we read stories from the aviation industry that their CO2 emissions do not exceed 2% of a country’s total. We did not trust these fairy tales and decided to do some calculations on the Dutch emissions. Spoiler alert: aviation is not telling the truth.

Following the most recent numbers the Dutch Bureau for Statistics CBS announced in Holland 3.75 billion kilograms of kerosene was sold in 2016.

Burning 1 kg kerosene gives 3.14 kg of CO2, resulting from the chemical formula to transform one CH2-group (fuel) with atomic weight 14 to a CO2-molecule with atomic weight 44 (44 devided by 14 equals 3.14). Read more >

This week the Dutch government spent nearly 800 mln community money to gain a 14% interest in airliner Air France-KLM. Stock prices tumbled over 10% following the announcement of the purchase. French government is furious.

The Dutch bought the shares secretly, without sharing its intentions with other shareholders and the French government. As a result, the French are likely to block another term for KLM-CEO Pieter Elbers.

A week ago Elbers mobilized 25.000 KLM-employees to plead for another four years of his presidency of the company. This convinced AFKL-CEO Ben Smith to promise Elbers a new term. Read more >

The construction of a brand new airport near the world famous city of Machu Picchu in Peru destroys archaeological sites that are yet unexplored.

The airport aims to ease access of tourists to the former Inca capitol. Archaeologists, anthropologists and historians claim it will destroy cultural riches visitors come to see.

Nearly 200 Peruvian and international experts have signed a protest to the national government asking to suspend construction and consider relocation of the project.

The current location of the project overlooks Peru’s Sacred Valley, one of the first areas conquered by the Incas in the 1300s. Incan agricultural terraces still cover the mountainsides around this spot. Read more >

We just opened a new Twitter-account for the Explane-app. Via this account we’ll inform you about the newest developments in our work.

The first tweet mentions the 4.000 registrations that have already been made since we launched the app.

@SchipholWatch already 4000 registrations with this the Explane app https://t.co/ZigqtxQOlr. I am working hard on producing interactive web reports with @AzureFunctions and @PowerBI
It will be amazing and a give insight in the real noise nuisance due to airports.

— Explane (@AppExplane) February 9, 2019

Also we mention the hard work that is going on to produce an interactive web site to present reports. The registrations will be accessible for anyone with an interest in the problem op aviation noise and its nuisance.

You can follow Explane via https://twitter.com/AppExplane (tech) or https://www.facebook.com/explane.org/ (news).

After years of consultation between residents, the aviation industry and politicians, earlier today became clear that there will be no outcome of this process. Parties could not reach an agreement about the future of the airport.

In December last year the consultation seemed to head up to an extra 25,000 flights for Schiphol until 2023. At the beginning of this year the president of the residents was taken out of the talks because of this threatening outcome.

Since the forced change of the spokesman residents forced a zero growth in the negotiations. Mayors and politicians of neighbouring cities and the Environmental Federation (Milieufederatie) backed citizens in that pursuit . Read more >

Since we have released the iOS- and Android-versions of our app to document aviation noise, we have started to build our website to publish the results online. And you can help us with your ideas!

Obviously we will publish lists of the highest sound level measurements. You will be able to select the area, the dates, the type of airplane or the aviation company. Also we will produce a realtime map displaying the measured noise levels.

Do you have other ideas about how we could present our data to our visitors? Please share them with us. Use our feedback form or send your ideas to info@schipholwatch.nl. Read more >

After months of hard work in spare time, app builder Roelof Meijer has released the iOS-version of this app today.

The iOS-version is intended for users of Apple’s iPhone. The app is called ExplaneNow in the Appstore and can be downloaded via https://itunes.apple.com/nl/app/explanenow/id1448049191 or via https://explane.org.

The Explane-app is intended to document aviation noise. As a resident, you can register the noise of an airplane with one push on a button. The app records the peak sound level, your location, the date and time, and finds the ID of the flight that is causing the noise.

All these data you can send to our central database which will be soon be published via our site https://explane.org. The data will be accessible for anyone who has an interest in the widespread nuisance of aviation noise. The data can be used to oppose calculations made by airports and (local) governments that often predict noise levels too low. Read more >

Our first episode of Tips & tricks stated that you best use our app outside your home. We’ve received replies from people who want to have a button in the app so they can indicate they measured noise inside their homes.

We will not provide such a button. Instead we kindly ask you again to use the app outdoors only.

The reason for this is quite simple: measuring aviation noise inside your home will not give us usable values of the noise level. There are homes that are very well insulated, while others aren’t. Measuring inside introduces a new uncertainty in the data.

The Explane-app is meant to collect as good as possible information about aviation noise and its nuisance. Read more >

Earlier this week Amsterdam Airport Schiphol released its third (!) review of its Environmental Impact Assessment. The report is (again) incorrect on a number of important points.

This conclusion follows from reports written by the Dutch Environmental Federation, consulting firms PWC and MovingDot.

According to its own EIA, Schiphol can grow to handle 540.000 flights a year, 40.000 more than currently permitted.

Not the environment, but the capacity at air traffic control is the limiting factor, according to the airport’s report.

“The calculations on a number of points are not carried out according to standards, wrong assumptions are used en the method provides a too low estimate of noise pollution”, say the critics. Read more >

Users of our app document aviation noise levels. Our aim is to publish the results on our site. Here’s a preview of what you can expect:

Our site will offer visitors the possibility to view the collected data in various ways. Above an example of measurements with their geolocation and their noise level. The darker the dots, the more noise.

From such a map you can zoom in and out to view details for your neighboorhood. The example shows The Netherlands since we’ve started here, but the app works worldwide!
