On 1 December 2023, Istat releases on its data warehouse – National accounts theme, the 2008-2021 time series for the Environmental accounts/NAMEA air emissions sub-theme, and provisional data for 2022 on greenhouse gas (GHG) emissions.
From this edition onwards, the conversion of greenhouse gases to CO2 equivalents is based on the Global Warming Potential (GWP) of the IPCC Fifth Assessment Report – AR5, referred to a 100-year time horizon.
The 2008-2021 time series concern air emissions of 24 pollutants by economic activities, classified in 64 industries and households (3 consumption functions). The provisional 2022 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.
In 2022, GHG emissions from the Italian economy amount to 429 million tonnes of CO2 equivalent, 0,1% more than in 2021, attenuating the downward trend observed since 2008 (-27.0% over the period 2008-2022).
GHG emissions from industries increase by 0.7% in 2022, mainly due to the contribution of producers of electricity, gas, steam and air conditioning and transport industries, which increase by 6.4 % and 4.4% respectively compared to the previous year, against a general decrease in other economic activities. Households, on the other hand, reduce emissions by 1.3% overall, due to the combined effect of a 12.4% decrease in emissions from heating and a 8.1% increase in emissions from transport.
