Seismic risk
In the Civil Protection Department's list of comuni, updated in May 2025, Treviso is in zone 2, where strong earthquakes are possible. The classification is used mainly for planning and land control; the design values for buildings depend on the coordinates of each construction.
Floods
According to the municipal sheet on IdroGEO, ISPRA's platform on hydrogeological instability, areas of high flood hazard (P3) cover 5.1% of the comune's roughly 55.5 km², with 3,390 residents exposed (4.2%). The sheet records no areas of high or very high landslide hazard.
Heating and air quality
To limit air pollution the Comune sets, each season and by a dedicated measure, the dates on which heating systems may run; for the 2026/27 season, in public buildings and offices, private offices, leisure and worship venues (cinemas, theatres, museums, libraries, bars, restaurants) and shops, heating, including wood-biomass systems, may not be switched on before 1 November 2026 and must be switched off on 12 April 2027. Schools, hospitals, care homes and private homes are excluded; for homes the guidance published by the Comune in previous years applies.
