Summary
- Protesters in Rho called for a moratorium on new data centre approvals and a cumulative environmental assessment of projects around Milan.
- Three projects are proposed within Rho itself, while wider development is also advancing across neighbouring municipalities.
- The campaign is pushing planning scrutiny from individual sites towards cumulative power, environmental, and land use effects.
Around 600 residents and campaigners marched through Rho, near Milan, on Saturday to demand a halt to new data centre approvals and a wider assessment of the cumulative impact of projects planned across the surrounding area.
The protest brought together local groups including SOS Fornace, environmental campaigners, and neighbourhood organisations. Reuters photographs from the demonstration recorded calls for a freeze on new approvals, a halt to ongoing projects, and a comprehensive environmental assessment of the area’s expanding digital infrastructure.
Three data centre projects are proposed in Rho itself, with further developments planned across neighbouring municipalities in the wider Milan area.
The campaign is focused less on one individual facility than on the cumulative effect of multiple developments. Protest material has raised concerns about electricity demand, noise, heat, backup generator emissions, fuel storage, and the scale of permanent industrial land use.
That distinction is increasingly important in European data centre planning. An individual project can be assessed against a particular site, connection, and environmental envelope, while a cluster of projects may place simultaneous demands on the same substations, water systems, roads, and communities.
Rho’s municipal administration has been responding publicly to the debate. On 2 October, mayor Andrea Orlandi published answers to questions about the projects around Via Moscova, while the deadline for observations on that development has been extended to 12 October.
The municipal engagement shows that opposition is now influencing the planning process before all proposed capacity reaches construction. Campaigners are asking for a strategic environmental assessment rather than relying solely on project by project procedures, arguing that separate approvals can obscure the aggregate effect of several facilities being developed within a relatively small area.
Milan and its surrounding industrial municipalities have become an important target for data centre investment because of connectivity, commercial demand, and access to established infrastructure. As development spreads beyond existing locations, however, projects increasingly collide with residential districts and competing land uses.
The Rho protest also reflects a broader change in how data centre developments are being contested. Earlier community disputes often centred on the appearance or noise of a single proposed building. The arguments now extend to whether local electricity networks can accommodate multiple large users, whether the economic benefits remain in the host municipality, and how digital infrastructure should be integrated into planning policy.
Those questions cannot be answered simply by classifying data centres as essential infrastructure. Digital capacity has economic and resilience value, but each facility still requires land, grid capacity, mechanical plant, backup systems, and physical access. Where several projects converge, the infrastructure consequences become collective even when developers submit separate applications.
The immediate outcome in Rho will depend on the municipal and regional planning processes attached to the individual projects. The demonstration does not itself stop construction or overturn an approval.
It does, however, increase pressure on authorities to explain how the full pipeline will be assessed. With campaigners preparing further mobilisation in Milan, operators and planning bodies around the city are likely to face greater scrutiny not only over what each project consumes, but over how much development the area can accommodate as a cluster.
