In Hamburg's Altona district, a method is being tested that allows pollutants to be measured and evaluated live in the air. Are the temporary driving bans based on the French model coming closer to us in Germany?
As a result of the pandemic, air quality has improved worldwide, according to satellite images. But if a company from Hamburg has its way, it won't soon be necessary to climb into orbit in order to obtain information on nitrogen oxides, carbon dioxide, particulate matter, etc.
The company Breeze Technologies has installed 35 sensors in Altona, which cover the district in a network and take measurements there. The size of the entire area is 14 square kilometers, making it the largest of its kind - worldwide. A further 20 sensors are also distributed over the rest of the Hanseatic League city area. This makes it possible to provide daily and real-time information on air values.
But the measuring stations that have been put into operation so far are only the beginning, according to Breeze Technologies: "In the future, we want to be able to say for every street, for every block in the city quarter, how the air quality there is developing over time, so that we can then decide on intelligent measures for air pollution control.
Temporary driving bans, known mainly in France, have already been discussed. Here, driving bans for individual roads or entire areas could be imposed for a certain period of time on the basis of daily measurements. For our French neighbours, this is already the norm in everyday mobile life. There, however, the air values from the previous day plus the forecasts for the coming days are used as the basis for deciding on driving bans.
Is this model now also following in Germany and other European countries? Are the green environmental zones and diesel driving bans not yet sufficient?
