Baden-Württemberg: The LEZ of Stuttgart delivers good results

08 July 2019

The Ministry of Transport of Baden-Württemberg (Germany) draws positive conclusions from the implementation of the local Low Emission Zone (LEZ) during the first half of 2019.

Transport Minister Winfried Hermann evaluates positively the effect of the LEZ: "Our air pollution control measures are effective. That's good for the health of our citizens."

According to the city's registration statistics, one fifth of the old diesel cars (passenger cars Euro 5 and older) were replaced by cleaner vehicles in 2018, and another fifth (23%) of these old diesel cars have been replaced in the first half of 2019. "More than 10,000 vehicle owners in Stuttgart alone have left their old vehicles. It is good that many people from Stuttgart make their own contribution to clean air" emphasized Minister Hermann. In addition, there are now 3,800 electric vehicles in the largest city of Baden-Württemberg.

In the first four months of 2019, an average of 62,700 vehicles were driven daily in the streets of Stuttgart. This is around 2,000 vehicles less than in the same period of the previous year. "The decrease of 3% in traffic has a positive effect on air quality, also because it improves the steadiness of the traffic" said Minister Hermann.

At the most polluted measuring station located in the city of Stuttgart (i.e. Neckartor), the limit value of 40 micrograms per cubic meter of air is still clearly exceeded. However, the 56 micrograms measured in the first half of the year are well below the 2018 annual mean of 71 micrograms per cubic meter of air.

Further measures are being prepared or are being implemented - including a bus lane project, reducing the number of car lanes in the Neckartor area. Also previsions on implementing a Euro-5-Diesel-Ban at some hotspots are under way.
