The indicator illustrates the yearly trend in the number of projects under national jurisdiction subject to Environmental Impact Assessment (EIA), the distribution of the outcomes of environmental compatibility decisions over time, and their classification by project type. It reflects the response of the central public administration in environmental decision-making processes. In 2024, out of 247 assessed projects, 221 were issued positive EIA decisions with environmental conditions, and 26 received negative decisions.
Environmental Impact Assessment (EIA) is a process regulated by Title III of Part II of Legislative Decree 152/2006 and subsequent amendments. It involves the preparation and submission of the Environmental Impact Study by the project proponent, public consultations, the evaluation of the study and any additional information, and the final EIA decision regarding the environmental impacts of the project. This decision is then integrated into the final approval or authorization of the project.
The technical assessment is carried out by:
The Technical Commission for Environmental Impact Assessment – EIA and SEA (CTVA), established by Ministerial Decree No. 342 of 13 December 2017, for general projects and plans.
The PNIEC-PNRR Commission, established by Ministerial Decree No. 361 of 2 September 2021, for projects funded under the National Recovery and Resilience Plan (PNRR) and the National Integrated Energy and Climate Plan (PNIEC).
These bodies issue a reasoned opinion that forms the basis for the final EIA decree issued by the Ministry of the Environment and Energy Security (MASE), in agreement with the Ministry of Culture (MiC).
An EIA decree is a reasoned, binding, and mandatory decision expressing the competent authority’s conclusion on the significant environmental effects of a project, based on technical evaluation, public consultation, and any cross-border consultation.
Illustrate the trend over the years in the number of works subject to EIA, in accordance with the provisions of current regulations, the distribution of the results of environmental compatibility rulings and their distribution according to the different types of works.
Therefore, the main purpose of the indicator is to provide information on the response of the central public administration regarding the decision-making processes related to environmental assessments.

Indicator assessment
The individual EIA measures under state competence were collected and analyzed. Starting from the measures published on the MASE website, data were processed relating to the total number of measures, positive, negative, negative and archived for each year. The measures extending the validity of the measures already issued have not been counted.
The types of projects subject to nationally regulated EIAs have changed over the years in response
to European Directives and national legislation. In 2024, out of 247 projects examined, 221 positive
EIA decisions with environmental conditions were issued, along with 26 negative ones (Table 1).
From June 1989 to 2024, a total of 1,708 projects were examined, resulting in 1,357 positive EIA
decisions, 185 negative, 69 conditionally negative, and 97 archived decisions (Table 1 and Figure
1). The trend can be considered positive, as the average number of annual decisions in the last ten
years (84) exceeds the 36-year average (47), indicating greater attention to the country’s sustainable
and economic development.

a Occurs when there is a substantial lack of information in the submitted documentation such that it is not possible to issue a judgment on the project's compatibility. This type existed until the enactment of Legislative Decree 128/2010 amending Legislative Decree 152/2006.
b Archived decision: when the proponent does not submit the additional documentation within the deadline set in the communication from the EIA Directorate of MASE. After this deadline or if the documentation remains incomplete upon verification, the application is archived.
Over the years, extension decisions for the validity of already issued decisions have been issued but were not counted.

* No longer present among the types of works to be subject to national EIA as they have been transferred among those to be subject to regional EIA. The works may be subject to a national EIA at the request of the region.
For the type of work Waste in 2013 there was a work subject to a national EIA procedure at the request of the region
Over the 36-year period considered, approximately 79% of submitted projects concluded with a positive EIA decision (Figure 2). Among the positive decisions (Figure 3), large transportation infrastructures stand out: highways, roads, airports, railway sections, and ports account for about a quarter of all issued authorizations. Next are renewable energy sources—onshore and offshore wind farms, photovoltaic and agrivoltaic plants—which represent nearly one-fifth of the total, highlighting a growing interest in decarbonization.
