In 2024, Fiera Milano unveiled one of the largest and most powerful rooftop photovoltaic system in Italy and among the top 10 in the world, located on the roofs of the exhibition site in Rho. The infrastructure, built thanks to the collaboration between Fondazione Fiera Milano and A2A through the creation of the Fair-Renew joint venture, consists of approximately 50,000 photovoltaic panels distributed over 330,000 square metres of pavilion roofing, equal to the surface area of 45 football pitches, which has an expected annual production of 21.6 GWh and a total installed capacity of 18 MWp,

The project is part of the Group's broader Decarbonization Plan to 2030.

Fiera Milano has installed, in partnership with Coripet, three compactors along the central axis of the Rho exhibition center (Milan), for the collection of PET plastic bottles which are recovered to produce new food packaging.

For each bottle inserted by visitors and employees into the compactors, they receive points for personal shopping and well-being, managed on a dedicated app.

Fiera Milano, in partnership with Montecolino S.p.A., has been recovering and reusing the carpet laid during events since 2017. As a result of this synergy, the creation of innovative and sustainable panels made from recycled carpet was born, which can be used for the preparation of pre-fitted and customized booths. The initiative represents a virtuous example of circular economy resulting from the engagement between Fiera Milano and one of its main suppliers for the sustainable development of the business.
