PREMESSA
Nell’ambito degli strumenti e delle politiche per fronteggiare i cambiamenti climatici, un ruolo fondamentale è svolto dal monitoraggio delle emissioni dei gas climalteranti.
A garantire questa funzione, in Italia, è l’ISPRA (ex APAT) su incarico del Ministero dell’Ambiente e della Tutela del Territorio e del Mare, attraverso le indicazioni del Decreto Legislativo n. 51 del 7 marzo 2008 e, più di recente, del Decreto Legislativo n. 30 del 13 marzo 2013, che prevedono l’istituzione di un Sistema Nazionale, National System, relativo all’inventario delle emissioni dei gas-serra.
L’ISPRA, infatti, realizza ogni anno l’inventario nazionale delle emissioni in atmosfera, che è strumento indispensabile di verifica degli impegni assunti a livello internazionale sulla protezione dell’ambiente atmosferico, come la Convenzione Quadro sui Cambiamenti Climatici (UNFCCC), il Protocollo di Kyoto, la Convenzione di Ginevra sull’inquinamento atmosferico transfrontaliero (UNECE-CLRTAP), le Direttive europee sulla limitazione delle emissioni.
In più, ogni Paese che partecipa alla Convenzione sui Cambiamenti Climatici, oltre a fornire annualmente l’inventario nazionale delle emissioni dei gas-serra secondo i formati richiesti, deve documentare in uno specifico documento, il National Inventory Report, le metodologie di stima utilizzate unitamente ad una spiegazione degli andamenti osservati.
Il National Inventory Report facilita i processi internazionali di verifica cui le stime ufficiali di emissione dei gas serra sono sottoposte. In particolare, viene esaminata la rispondenza alle proprietà di trasparenza, consistenza, comparabilità, completezza e accuratezza nella realizzazione, qualità richieste esplicitamente dalla Convenzione suddetta. L’inventario delle emissioni è sottoposto ogni anno ad un esame (review) da parte di un organismo nominato dal Segretariato della Convenzione che analizza tutto il materiale presentato dal Paese e ne verifica in dettaglio le qualità su enunciate. Senza tali requisiti, l’Italia sarebbe esclusa dalla partecipazione ai meccanismi flessibili previsti dallo stesso Protocollo, come il mercato delle quote di emissioni, l’implementazione di progetti con i Paesi in via di sviluppo (CDM) e l’implementazione di progetti congiunti con i Paesi ad economia in transizione (JI).
Questo processo di review diviene tanto più importante a mano a mano che i dati prendono in considerazione la fase conclusiva del primo periodo di impegno (2008-2012) del Protocollo di Kyoto, alla fine del quale sarà accertata la rispondenza tra gli impegni di riduzione assunti dai Paesi industrializzati e le rispettive emissioni di gas-serra.
Il rapporto “Italian Greenhouse Gas Inventory 1990-2011. National Inventory Report 2013” descrive la comunicazione annuale italiana dell’inventario delle emissioni dei gas serra dal 1990 al 2011.
Il documento è uno strumento fondamentale per la pianificazione e l’attuazione di efficaci politiche ambientali e fornisce alle istituzioni centrali e periferiche un adeguato contributo conoscitivo sulle problematiche inerenti ai cambiamenti climatici a livello settoriale. Le stime che esso contiene e le metodologie utilizzate dovrebbero essere considerate come riferimento per tutte le valutazioni relative agli obiettivi di riduzione delle emissioni, sia quelle a livello nazionale, sia quelle predisposte a livello regionale e locale, come quelle contenute nei Piani di azione per l’energia sostenibile previsti dal “Patto dei Sindaci”.

EXECUTIVE SUMMARY
ES.1. Background information on greenhouse gas inventories and climate change
The United Nations Framework Convention on Climate Change (FCCC) was ratified by Italy in the year 1994 through law no.65 of 15/01/1994.
The Kyoto Protocol, adopted in December 1997, has established emission reduction objectives for Annex B Parties (i.e. industrialised countries and countries with economy in transition): in particular, the European Union as a whole is committed to an 8% reduction within the period 2008-2012, in comparison with base year levels. For Italy, the EU burden sharing agreement, set out in Annex II to Decision 2002/358/EC and in accordance with Article 4 of the Kyoto Protocol, has established a reduction objective of 6.5% in the commitment period, in comparison with 1990 levels.
Subsequently, on 1st June 2002, Italy ratified the Kyoto Protocol through law no.120 of 01/06/2002. The ratification law prescribed also the preparation of a National Action Plan to reduce greenhouse gas emissions, which was adopted by the Interministerial Committee for Economic Planning (CIPE) on 19th December 2002 (deliberation n. 123 of 19/12/2002).
The Kyoto Protocol finally entered into force in February 2005.
As a Party to the Convention and the Kyoto Protocol, Italy is committed to develop, publish and regularly update national emission inventories of greenhouse gases (GHGs) as well as formulate and implement programmes to reduce these emissions.
In order to establish compliance with national and international commitments, the national GHG emission inventory is compiled and communicated annually by the Institute for Environmental Protection and Research (ISPRA) to the competent institutions, after endorsement by the Ministry for the Environment, Land and Sea. The submission is carried out through compilation of the Common Reporting Format (CRF), according to the guidelines provided by the United Nations Framework Convention on Climate Change and the European Union’s Greenhouse Gas Monitoring Mechanism. As a whole, an annual GHG inventory submission shall consist of a national inventory report (NIR) and the common reporting format (CRF) tables as specified in the Guidelines on reporting and review of greenhouse gas inventories from Parties included in Annex I to the Convention, implementing decisions 3/CP.5 and 6/CP.5, doc. FCCC/SBSTA/2002/L.5/Add.1.
Detailed information on emission figures and estimation procedures, including all the basic data needed to carry out the final estimates, is to be provided to improve the transparency, consistency, comparability, accuracy and completeness of the inventory provided.
The national inventory is updated annually in order to reflect revisions and improvements in the methodology and use of the best information available. Adjustments are applied retrospectively to earlier years, which accounts for any difference in previously published data.
This report is compiled according to the guidelines on reporting as specified in the document FCCC/SBSTA/2002/L.5. It provides an analysis of the Italian GHG emission inventory communicated to the Secretariat of the Climate Change Convention and to the European Commission in the framework of the Greenhouse Gas Monitoring Mechanism in the year 2013, including the update for the year 2011 and the revision of the entire time series 1990-2010.
The assigned amount for Italy, pursuant to Article 3, paragraphs 7 and 8 and calculated in accordance with the annex to decision 13/CMP.1, has been established together with the commitment period reserve (CPR), required in accordance with paragraph 18 of decision 15 CMP.1, during the last in country review in 2007.
The calculated figures are reported in the document FCCC/IRR/2007/ITA and amount to 2,416,277,898 tonnes CO2 eq. for the assigned amount and 2,174,650,108 tonnes of CO2 eq. for the CPR. The CPR is calculated on the basis of the assigned amount and it has not changed from the previous submission.
Emission estimates comprise the six direct greenhouse gases under the Kyoto Protocol (carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulphur hexafluoride) which contribute directly to climate change owing to their positive radiative forcing effect and four indirect greenhouse gases (nitrogen oxides, carbon monoxide, non-methane volatile organic compounds, sulphur dioxide).
This report, the CRF files and other related documents are available on website at the address http://www.sinanet.isprambiente.it/it/sia-ispra/serie-storiche-emissioni.
The official inventory submissions can also be found at the UNFCCC website http://unfccc.int/national_reports/annex_i_ghg_inventories/national_inventories_submissions/items/7383.ph
ES.2. Summary of national emission and removal related trends
Total greenhouse gas emissions, in CO2 equivalent, excluding emissions and removals of CO2 from land use, land use change and forestry, decreased by 5.8% between 1990 and 2011 (from 519 to 489 millions of CO2
equivalent tons), whereas the national Kyoto target is a reduction of 6.5%, as compared to the base year levels, by the period 2008-2012.
The most important greenhouse gas, CO2, which accounted for 84.7% of total emissions in CO2 equivalent in 2011, showed a decrease by 4.7% between 1990 and 2011. In the energy sector, specifically, CO2 emissions in 2011 reduced of 2.8% as compared those in 1990.
CH4 and N2O emissions were equal to 7.5% and 5.5%, respectively, of the total CO2 equivalent greenhouse gas emissions in 2011. Both gases showed a decrease from 1990 to 2011, equal to 16.4% and 28.1% for CH4
and N2O, respectively.
Other greenhouse gases, HFCs, PFCs and SF6, ranged from 0.1% to 1.9% of total emissions.
Table ES.1 illustrates the national trend of greenhouse gases for 1990-2011, expressed in CO2 equivalent terms, by substance and category.

ES.3. Overview of source and sink category emission estimates and trends
The energy sector is the largest contributor to national total GHG emissions with a share, in 2011, of 82.7%.
Emissions from this sector decreased by about 3.2% from 1990 to 2011. Substances with decrease rates were CO2, whose levels reduced by 2.8% from 1990 to 2011 and accounts for 97.1% of the total in the energy sector, and CH4 which showed a reduction of 25.3% but its share out of the sectoral total is only 1.7%; N2O, on the other hand, showed an increase of 6.8% from 1990 to 2011 but it is not relevant on total emissions, accounting for 1.2%. Specifically, in terms of total CO2 equivalent, an increase in emissions was observed in the transport sector, and in the other sectors, about 14.3% and 9.7%, from 1990 to 2011, respectively; in 2011 these sectors, altogether, account for 50.4% of total emissions.
For the industrial processes sector, emissions showed a decrease of 17.6% from the base year to 2011.
Specifically, by substance, CO2 emissions account for 63.8% and showed a decrease by about 29.0%, CH4
decreased by 46.4%, but it accounts only for 0.2%, while N2O, whose levels share 0.9% of total industrial emissions, decreased by 95.6%. The decrease in emissions is mostly due to a decrease in chemical industry (due to the fully operational abatement technology in the adipic acid industry) and metal production emissions. A considerable increase was observed in F-gases emissions (about 250.5%), whose level on total sectoral emissions is 35.1%. It should be noted that, except for the motivations explained, the economic recession has had a remarkable influence on the production levels of most the industries and consequent emissions in the last two years.
Emissions from the solvent and other product use sector, which refer to CO2 and N2O emissions except for pollutants other than greenhouse gases, decreased by 32.5% from 1990 to 2011. The reduction is mainly to be attributed to a decrease by 34.3% in CO2 emissions, which account for 65.2% of the sector. As regards CO2, emission levels from paint application sector, which accounts for 50.4% of total CO2 emissions from this sector, decreased by 35.6%; emissions from other use of solvents in related activities, such as domestic solvent use other than painting, application of glues and adhesives, printing industries, fat edible and non edible oil extraction, vehicle dewaxing, glass wool enduction, which account for 43.9% of the total, show a decrease of 23.8%. Finally, CO2 emissions from metal degreasing and dry cleaning activities, decreased by 65.1% but they account for only 5.7% of the total.
The level of N2O emissions shows a decrease of 29.0%, accounting for 34.8% of total emissions in the sector in 2011.
For agriculture, emissions refer to CH4 and N2O levels, which account for 43.1% and 56.9% of the sectoral total, respectively. The decrease observed in the total emissions (-17.7%) was mostly due to the decrease of CH4 emissions from enteric fermentation (-12.4%), which account for 32.1% of sectoral emissions and to the decrease of N2O from agricultural soils (-21.1%), which accounts for 45.8% of sectoral emissions.
As regards land use, land-use change and forestry, from 1990 to 2011 total removals in CO2 equivalent increase by 151.7%; CO2 accounts for almost the total emissions and removals of the sector.
Finally, emissions from the waste sector decreased by 10.9% from 1990 to 2011, mainly due to a decrease in the emissions from solid waste disposal on land (-17.8%), which account for 71.5% of waste emissions. The most important greenhouse gas in this sector is CH4 which accounts for 87.5% of the sectoral emissions and shows a decrease of 11.4% from 1990 to 2011. N2O emission levels increased by 5.0%, whereas CO2
decreased by 53.8%; these gases account for 11.2% and 1.3%, respectively.
