European cities are showing significant progress in combating air pollution, according to data collected from active official traffic air quality stations. There are positive trends which translate to cleaner air for residents, with reductions in harmful pollutants like PM2.5 and NO2. This article explores the known strategies that these cities have implemented to achieve such remarkable improvements, offering valuable insights for other urban centers striving for a healthier future.

These are the 5 cities and traffic air quality stations that I have analyzed data from.

  • Berlin DEBE068 (B Mitte, Brückenstraße)
  • Madrid ES0118A (Escuela Aguirre)
  • Rome IT1906A (Arenula)
  • Paris FR04012 (Place Victor Basch)
  • Athens GR0003A (Aristotelous)

The European Union Agreed on New Rules & PM2.5/NO2 Limits for Cleaner Air

Sotirios Papathanasiou7 Comments

On February 20, 2024, the Council of the EU released a press release that discusses the agreement reached by the Council and Parliament to strengthen air quality standards in the EU. The new standards are expected to improve air quality and reduce premature deaths. They will be reviewed regularly and could be further strengthened in the future.

EU lawmakers have joined forces to strengthen air quality standards by 2030. These new, stricter limits and targets align more closely with World Health Organization (WHO) recommendations and will be subject to regular review. The updated directive tackles a range of air pollutants, including fine particles (PM2.5 and PM10), nitrogen dioxide (NO2), sulphur dioxide (SO2), and even toxic metals like arsenic and lead. Each pollutant has its own specific standard, with the most significant reductions targeting those posing the greatest health risks. For example, annual limits for PM2.5 and NO2 will be more than halved, dropping from 25 µg/m³ to 10 µg/m³ and 40 µg/m³ to 20 µg/m³, respectively.

Warming Up your Vehicle in Winter is Dangerous for your Health & Illegal (US Version)

Sotirios PapathanasiouLeave a comment

As we face the frigid temperatures brought by polar vortexes in the US, the last thing anyone wants is to enter a freezing cold car. However, it is important to note that in many states, warming up your vehicle by letting it idle is actually illegal.

Regardless of the duration, idling is considered an automatic misdemeanor in most states. Surprisingly, even using the automatic start feature on your car can be against the law in some states. The penalties for idling vary depending on the jurisdiction. For example, in Washington D.C., you could face a $5,000 fine if your car idles for just three (3) minutes. However, some states are more lenient, like Pennsylvania, where idling is allowed for up to twenty (20) minutes when the temperature is below 40ºF (4ºC).

Why every Car needs a CO2 Monitor/Sensor?

Sotirios Papathanasiou3 Comments

Let’s forget at the moment that combustion vehicles emit carbon dioxide (CO2), and focus on the occupants that spend time inside a confined space where they emit CO2 due to metabolite of cell respiration. Vehicles form part of the indoor spaces where humans spend a lot of time due to traffic or because they have to travel long distances.

Regulatory bodies have been controlling many aspects of modern vehicles; tires, mirrors, seat belts, airbags, screens, etc. However, they have forgotten to look into the air quality inside the vehicles and how it affects the driver’s cognitive performance.
