In Italy a state EIA takes a median of 2.7 years, and 21 in 100 end with a negative opinion.

In the catalogue of the MASE Environmental Assessments portal, the median concluded EIA takes 982 days under the PNIEC-PNRR regime, about 2.7 years, and 1,087 days under the ordinary regime. Only procedures concluded with a start and a decision date are counted: those still open, often the longest, are not.

Of the 619 EIAs concluded with a known outcome, 21 in 100 were negative, 71 in 100 positive with conditions and 8 in 100 positive without conditions. Measured on 6 October 2026.

The median is 287 days under the ordinary regime and 249 days under the PNIEC-PNRR regime. Of the screenings concluded with a known outcome, 62 in 100 exclude the project from the EIA and 15 in 100 refer it to an EIA.

The environmental parts of the study: the baseline of the site measured from satellite and in the field (land use, biodiversity, protected areas and nearby Natura 2000 sites, water, climate and risks), the impact assessment, the mitigation and compensation measures and the monitoring plan. Every document is signed by an expert of the team.

Yes: we analyse the habitats and species of the Natura 2000 sites near the project and prepare the mitigation measures. Among the example reports you can download is the technical answer to the five conditions of an appropriate assessment for a solar plant.
