On November 28 2022, Istat releases on its data warehouse I.Stat – ‘National accounts’ theme, the 2008-2020 time series for the ‘Environmental accounts/NAMEA air emissions’ sub-theme, and provisional data for 2021 on greenhouse gas (GHG)  emissions.

The 2008-2020 time series concern air emissions of 24 pollutants by economic activities, classified in 64 industries and households (3 consumption functions). The provisional 2021 data are released with a detail of 38 industries.

Air emissions accounts are compiled in accordance with EU Regulation 691/2011 and the consistency with national accounts data make them suitable for integrated environmental-economic analyses.

Air emissions accounts are calculated starting from the national emission inventory annually produced by Istituto Superiore per la Ricerca e la Protezione Ambientale (Ispra).

Additional information disseminated by Istat are:

  • a bridge table devoted to show the link between air emission totals and totals calculated by Ispra and used for Italian Communications within the framework of international conventions: United Nations Framework Convention on Climate Change (UNFCCC) and the UNECE Convention on Long-range Transboundary Air Pollution (CLRTAP);
  • emission intensity of production, value added and employment.

2021 GHG emissions from the Italian economy amounted to 416 million tons of CO2 equivalent, 6.2% more than in 2020. Although increasing compared to the previous year, GHG emissions do not reach the levels of the pre-pandemic period, confirming the downward trend observed starting from 2008 (-28.7% over the period 2008-2021)

The share of GHG emissions due to industries is 74.9% mainly generates by manufacturing industries (21.1% of emissions) and producers of electricity, gas, steam and air conditioning (18.8%). 2021 GHG emissions caused by industries increased by 6.4% compared the previous year.

Households are responsible for the remaining 25.1% of emissions, mainly due to their own heating and transport activities. Household emissions increased by 5.7% compared to 2020.

Data are also released on IstatData , the Istat’s new aggregate data dissemination platform that will gradually replace the I.Stat data access system. Until the data transfer is completed, the two systems will coexist.
