Welcoming the challenge of environmental sustainability and higher quality of life. A city with less traffic on the streets is a less polluted and more liveable city.


The new metro line promises the concrete reduction of air and noise pollution: once fully operational, it is estimated that the M5 line will lead to a reduction of 15 million private car trips a year and, therefore, a significant decrease in pollutants.
Moreover, savings equal to 8,470 tonnes of oil per year is expected as well as 260 less road accidents a year in the city.

Thanks to the 12.8 kilometres and 19 stations of the entire purple line, it will be possible to transport between 15 and 18 thousand passengers per hour per direction (pphpd), with an average demand of 6,500-7,500 pphpd, and will offer a peak frequency of 90 seconds, which may reach 75 on the line. This cutting-edge mobility system in terms of performance and safety is able to accommodate 60 million passengers per year.


Greenery in the city is not only beautiful but also useful because it has positive effect on air quality and the ecosystem. Where possible, trees are simply moved from the surface of the construction sites and planted in alternative sites before returning home once the works have been completed.

The creation of the M5 metro line immediately delivers Milan a new heritage of green public spaces. According to the logic of biodiversity and environmental advantage, the number of trees will increase: more than three new trees (more precisely: 3.6 shrubs at least twelve years of age) will take root in the city for every tree removed during the construction phase.
This compensation is perfectly in line with the Kyoto Protocol and is set to triple the current levels of fine dust and carbon dioxide absorption.
