3.1. Data description
Data presents environmental tax revenue (by tax category - energy, transport, pollution and resource taxes) broken down by economic activity (tax payer), using the NACE classification for production activities extended to cover taxes payable by households and non-residents.
3.2. Classification system
Environmental tax revenue is broken down by:
A. type of environmental tax,
B. sector/industry of tax payer
A. Classification according to type of environmental tax
For analytical purposes, the environmental taxes are divided into four categories:
1. energy taxes (split into ETS CO2 taxes and other CO2 taxes),
2. transport taxes,
3. pollution taxes,
4. resource taxes (excluding taxes on oil and gas extraction).
B. Environmental taxes by economic activity
Environmental tax revenues are allocated to the different tax payers:
• by economic activity according to the statistical classification of economic activities in the European Community (NACE Rev.2)
• households as consumers
• non-residents
• not allocated (impossible to be allocated to one of the categories mentioned above)
3.3. Coverage - sector
Environmental taxes by economic activity data cover taxes payable by all sectors of the economy: producers (economic activities by NACE), households as consumers as well as non-residents.
3.4. Statistical concepts and definitions
The environmental tax statistics are compiled based on Eurostat’s 2013 'Environmental taxes - a statistical guide'. Environmental tax is defined as "A tax whose tax base is a physical unit (or a proxy of a physical unit) of something that has a proven, specific negative impact on the environment, and which is identified in ESA2010 as a tax".
Environmental tax statistics are part of European environmental economic accounts, which constitute satellite accounts to national accounts. Thus, environmental tax statistics follows ESA2010 definition of ‘taxes’. Consequently, only payments that are identified as taxes in the national accounts can be reported as environmental taxes whereas other types of payments to government are not excluded from the scope of the data collection. Compliance with the tax definition of the national accounts improves international comparability of the statistics, and is in line with the guidance, concepts and definitions of the System of environmental and economic accounting (SEEA).
3.5. Statistical unit
Data refer to environmental taxes collected by the government and payable by the different economic agents.
3.6. Statistical population
The target population are all production sectors by NACE, households as consumers and non-residents.
3.7. Reference area
Italy
3.8. Coverage - Time
Environmental tax revenue (by tax category - energy, transport, pollution and resource taxes) broken down by economic activity (tax payer) is currently available for 2008-2023.
3.9. Base period
Not applicable.
Million National Currency (MNAC)
The data refer to the calendar years.
6.1. Institutional Mandate - legal acts and other agreements
Statistics on environmental taxes are based on Regulation (EC) No. 691/2011 (Annex II) on European environmental economic accounts as amended by Regulation 538/2014 , as well as legal acts in the area of national accounts; since 2022 data reporting also takes into account the requirements established in the Commission delegated regulation 2022/125. Data transmission became obligatory in September 2013. Before, Eurostat collected the data on a voluntary basis.
The basis for the national accounts tax aggregates is Table 9 "Detailed tax and social contribution receipts by type of tax or social contribution and receiving sub-sector including the list of taxes and social contributions according to national classification" of the ESA2010 transmission programme - Annex B of Regulation (EU) No. 549/2013 of the European Parliament and of the Council of 21 May 2013 on the European system of national and regional accounts in the European Union. Moreover, Commission Regulation (EC) N° 995/2001 of 22 May 2001 implementing Council and European Parliament Regulation (EC) N° 2516/2000 of 10 July 2000 on the recording of taxes and social contributions sets the rules for the data sources, time of recording and comparable treatment of taxes and social contributions assessed but unlikely to be collected.
6.2. Institutional Mandate - data sharing
Not applicable.
7.1. Confidentiality - policy
Information collected is protected by professional secrecy (Article 8 of Legislative Decree No. 322/1989), statistical confidentiality (Article 9 of Legislative Decree No. 322/1989).

15.1.1. Asymmetry for mirror flow statistics - coefficient
Not applicable.
15.2. Comparability - over time
The calculation process does not cause break in time series. Most data sources are quite homogenous for the whole time series thus reducing the likelihood of a discontinuity in the data.
However, there are the following break in the time series:
- in 2019 due to the revision of basic data on electricity use by economic activity used to split total revenue from electricity.
- in 2011 due to an update from this year onwards of input data used to split total revenue on 'Public motor vehicle register tax' by economic activity.
- in 2021 due to the use of a new data source to split system charges for renewable energy by economic acitvities
Some environmental taxes are not in operation for the entire reporting period. These cases are reported in detail in the section - comparability over time - detailed.
15.2.1. Length of comparable time series
The calculation process does not cause break in time series. Most data sources are quite homogenous for the whole time series thus reducing the likelihood of a discontinuity in the data.
Some environmental taxes are not in operation for the entire reporting period, these cases are reported in detail in the section - comparability over time - detailed.

2011 due to an update from this year onwards of input data used to split total revenue on 'Public motor vehicle register tax' by economic activity 'Revenues of the Italian Central Stockholding Entity: tax is in operation since 2013 Emission permits (ETS CO2 tax): altough the tax is in operation since 2013 the revenue is accounted since 2014 onwards consistently with the new Manual (MGDD, 2022). 2019 - break in the time series concerning specific economic activities due to the revision of electricity use basic data. introduction of the new, temporary "Tax on surplus from renewable energy production" in 2022 and eliminated in 2023 2021 - break in series due to the use of a new data source to split system charges for renewable energy by economic acitvities |
| Transport taxes |
2011 onwards, 2012 onwards, 2019 onwards |
There is a break in the compilation method for the following tax: from 2011 due to an update from this year onwards of input data used to split total revenue for 'Public motor vehicle register tax' In addition
|
| Pollution taxes |
1996 onwards |
There is no break in the compilation method but please notice that the regional special tax on landfill dumping was introduced in 1996 |
| Resource taxes |
2018 onwards |
Following the 2024 general revision of Italian national accounts a new tax on water consumption is accounted for. In NTL it is included in the wider tax "Special duties similar indirect tax on products". |
15.3. Coherence - cross domain
Environmental tax data are derived from the ‘General Government aggregates and Accounts’ (Conti ed aggregati economici delle Amministrazioni pubbliche) calculated by Istat’s National Accounts.
Environmental taxes are selected within the National Accounts taxes by applying the Eurostat’s guidelines on environmental tax statistics and accounts.
15.3.1. Coherence - sub annual and annual statistics
Not applicable
15.3.2. Coherence - National Accounts
Environmental tax data are derived from the ‘General Government aggregates and Accounts’ (Conti ed aggregati economici delle Amministrazioni pubbliche) calculated by Istat’s National Accounts. The 2025 ETEA is consistent with the March 2025 NTL.

between 2% and 23% |
In ETEA 2025 the sheet resource taxes is compiled for the first time and starting from year 2018. Estimates concerns a tax included in the Italian NTL in a larger tax item ('Special duties similar indirect tax on products) in which taxes other than environmental ones may be accounted for. This is the reason why in the Italian NTL this item of tax has a flag other than P/RS, causing a significant diffence between total pollution and resource taxes in ETEA - both in the sheet of resource and in pollution taxes, row 76 - and total pollution and resource taxes from the NTL. |
15.4. Coherence - internal
The same vintage of source data are used to compile the ETEA data for a given year.
The only exception concerns tax 'Public motor vehicle register tax' for the years 2008-2011: input data used to split total revenue by economic activity belong to a time series dating before the general National account revision of 2024.
7 months FTE for the April 2025 data delivery.
17.1. Data revision - policy
The revision policy for ETEA data is as follows: update of t-3 and t-2 data in every data transmission due to the ordinary revisions of NA data sources. In addition, the entire time series may be updated on the occasion of national accounts other than ordinary revisions. This latter is the case for ETEA2025
Some changes may also occur in the time series due to revisions of input data.
17.2. Data revision - practice
ETEA2025 time series was entirely revised due to the general revision of italian national accounts of September 2024.
The following list details the revision, both ordinary and general ones, and update:
• minor revison of data on ‘Total surrendered units’ and ‘Freely allocated allowances’ from the European Environment Agency’s ETS database for the years 2020-2021 and of air emission accounts data for year 2022.
• revision of energy use data for the whole time series 2008-2022 for all NACEs, households and non-residents;
• revision of national accounts input data for the whole time series 2008-2022, consistently with the national accounts revision of September 2024, used as follows:

o to split Public motor vehicle register tax (PRA) / D214D_C01 by NACE;
o to split Motor vehicle duty paid by enterprises / D29B_C01;
o to split Regional special tax on landfill dumping / D214H_C03;
• upadate of total tax revenue for the whole time serie for Energy category, from 2011 for Pollution category and from 2014 for Transport category.
• Revision of methodology, of input data on energy use and of excise duty for assessment and splitting by NACEs of taxes for own production of electricity and of electricity for street lighting for the whole time series

• minor update of classification of input data used for splitting the tax 'SO2 and NOx pollution tax” by NACEs for years 2016-2022
• implementaion of a new methodology for an improved application of excise duty abatment, for some uses and for some NACEs (H59, H50, C22, C23, M71, Q86) on the basis of data input detailed at 4-digits level on ISIC classification
• revision of estimates for taxes on use of electricity for NACE 35 for year 2022 due to a calculation error.
17.2.1. Data revision - average size
• revision of energy use: greater then +20% and minor of -20% for the main energy products (diesel, gasoline, methan, electricity) for a large number of NACEs for different years of the whole time series
• 'Emission permits: -100% for year 2013 due to a new methodology according to the new Manual (MGDD, 2022); from -62% up to +32% for years 2015-2018 and 2021-2022
• -96% up to +677% for several NACEs and several years of the whole time serie due to the update of methodology and input data for taxes on electricity – see section 17.2;
• -95% for NACE 35 for year 2022 due to calculation error for the temporary “Tax on surplus from renewable energy production”;
• - 95% up to +451% for several NACEs and several years of the whole time serie due to the update of methodology and input data for system charges on renewable energy – see section 17.2
• 'Regional special tax on landfill dumping: range from -98% up to +960% for the whole time serie for a large number of NACEs due to revision in input data from national accounts – see section 17.2

• ‘'Public motor vehicle register tax’ from -98% up to 359% for years 2011-2022 for a large number of NACE due to revision of input data – see section 17.2.
• Tax on vehicles: from -78% up to 271% for a large number of NACE for all years of time series due to revision in input data – see section 17.2.
All other revisions listed in 17.2 are smaller than 20%
17.2.2. Status of data
The ETEA data up to t-3 can be considered final and t-2 can be considered provisional.
However, the entire time series may be updated in future national accounts other than ordinary revisions or due to changes in input data.

Most data sources are available for the whole reporting period up to the year t-2.
18.5.4. Compilation of revenue payable by non-residents
Taxes paid by non-residents - energy taxes: the amount of tax paid by non-residents is calculated for taxes on diesel oil and motor gasoline; the tax rate is multiplied by the quantity of fuels used by non-residents for international road transport, specifically:
- Diesel oil – road transport, sources: fuel use on the Italian territory by non-residents for households, the ‘non-residents’ component is estimated consistently with the adjustment for road transport calculated for air emission accounts;
- Motor gasoline – road transport, sources: fuel use on the Italian territory by non-residents for households, the ‘non-residents’ component is estimated consistently with the adjustment for road transport calculated for air emission accounts.
Taxes paid by non-residents - pollution taxes: the amount of tax paid by non-residents is calculated for the Regional tax on aircraft noise by means of transport statistics background data on the number of flights operated by non resident companies.
18.5.5. Compilation of revenue broken down by payer for years before 2008
The breakdown of revenue from environmental taxes by industry (NACE Rev. 2) and households for years before 2008 is currently not available due to the lack of some background data, namely energy use data.

The main data source for the environmental tax revenue are the Istat’s National Accounts ‘General Government aggregates and Accounts’ (Conti ed aggregati economici delle Amministrazioni pubbliche); specifically, the April 2025 ETEA is consistent with the NTL of March 2025.
Detailed data sources are described in the specific sections.
Annual until 2021, biannual since 2022
For the April 2025 data delivery production time was approximately 7 months (FTE). The estimated production time includes work to provide input for 2021, 2022 (years of benchmark), for backcasting of time series and for 2023 estimates.
Environmental taxes are selected within the National Accounts taxes by applying the Eurostat’s guidelines on environmental tax statistics and accounts. There is no case of taxes that are deliberately excluded or that are not mentioned in the ETEA handbook.
The calculation process does not cause break in time series. Most data sources are quite homogenous for the whole time series thus reducing the likelihood of a discontinuity in the data.
However, there are the following break in the time series:
- in 2019 due to the revision of basic data on electricity use by economic activity used to split total revenue from electricity.
- in 2011 due to an update from this year onwards of input data used to split total revenue on 'Public motor vehicle register tax' by economic activity.
- in 2021 due to the use of a new data source to split system charges for renewable energy by economic acitvities
Some environmental taxes are not in operation for the entire reporting period. These cases are reported in detail in the section - comparability over time - detailed.
