Enabling sustainable building and infrastructure

16 October 2019

Buildings and infrastructure form the very basis of societal development. They also account for about a third of worldwide CO2 emissions. Society urgently needs to create a more sustainable built environment using products and solutions with lower environmental impact. Holcim Italy has provided solutions to minimize the environmental impact and make CityLife buildings sustainable.


CityLife is connected by the new M5 metro line with high-density nodes such as Bicocca University and the San Siro football stadium. The M5 is used by over 130,000 passengers each day, thus eliminating 15 million car trips per year.

The Leadership in Energy and Environmental Design (LEED) certificate is the world’s leading green building rating system and a push for more builders to meet the sustainability challenge. We are proud that our materials helped the ‘twisted’ tower achieve the LEED standard. Holcim helped fulfil the requirements to score in the following categories: reduced impact of construction site operations, management of construction waste and use of recycled materials and products with low emission levels.

In addition, the quarries and plants surrounding the site have been instrumental in limiting the distance and environmental impact of transport. The trucks used for the operations complied with the local requirements of having the maximum European emissions standards (EURO 6). By using pozzolanic cement (which partially substitutes clinker with volcanic ash), we helped achieve low emission levels of the material used. Clinker is the main component of cement and it is during its production when most CO2 emissions associated with cement occur.
