PREMESSA

Nell’ambito degli strumenti e delle politiche per fronteggiare i cambiamenti climatici, un ruolo fondamentale è svolto dal monitoraggio delle emissioni dei gas-serra.

A garantire la predisposizione e l’aggiornamento annuale dell’inventario dei gas-serra secondo i formati richiesti, in Italia, è l’ISPRA 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.

In più, come è previsto dalla Convenzione-quadro sui cambiamenti climatici per tutti i Paesi industrializzati, l’ISPRA documenta in uno specifico rapporto, 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 a economia in transizione (JI).

Il presente documento rappresenta, inoltre, un riferimento fondamentale per la pianificazione e l’attuazione di tutte le politiche ambientali da parte delle istituzioni centrali e periferiche. Accanto all’inventario dei gas- serra, l’ISPRA realizza ogni anno l’inventario nazionale delle emissioni in atmosfera, richiesto dalla Convenzione di Ginevra sull’inquinamento atmosferico transfrontaliero (UNECE-CLRTAP) e dalle Direttive europee sulla limitazione delle emissioni. In più, tutto il territorio nazionale è attualmente coperto da inventari regionali sostanzialmente coerenti con l’inventario nazionale, realizzati principalmente dalle Agenzie Regionali e Provinciali per la Protezione dell’Ambiente.

Nonostante i progressi compiuti, l’attività di preparazione degli inventari affronta continuamente nuove sfide

legate alla necessità di considerare nuove sorgenti e nuovi inquinanti e di armonizzare gli inventari prodotti

per diverse finalità di policy. Il contesto internazionale al quale fa riferimento la preparazione dell’inventario

nazionale costituisce una garanzia di qualità dei dati, per l’autorevolezza dei riferimenti metodologici,

l’efficacia del processo internazionale di review e la flessibilità nell’adattamento alle nuove circostanze.

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 1 ^st 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 19 ^th December 2002 (deliberation n. 123 of 19/12/2002). The Kyoto Protocol finally entered into force in February 2005. The first commitment period ended in 2012, with an extension, for fulfilling commitments, to 18 ^th November 2015, the so called true-up period. The evaluation of the Kyoto Protocol, together with the commitments fulfilled by each Party, has been finalized by the UNFCCC Secretariat.

A new global agreement was reached in Paris in December 2015, for the period after 2020. The agreement aims to strengthen the global response to the threat of climate change by holding the increase in the global temperature to well below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels, recognizing that this would significantly reduce the risks and impact of climate change. On 5 ^th October 2016, the threshold for entry into force of the Paris Agreement was achieved and the Paris Agreement entered into force on 4 ^th November 2016.

To fulfil the gap 2013-2020, the ‘Doha Amendment to the Kyoto Protocol’ was adopted on 8 ^th December 2012.

The EU and its Member States have committed to this second phase of the Kyoto Protocol and established to reduce their collective emissions to 20% below their levels in 1990 or other chosen base years; this is also reflected in the Doha Amendment . The target will be fulfilled jointly with Iceland.

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, decision 24/CP.19, in FCCC/CP/2013/10/Add.3.

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 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 2000, including the update for the year 2018 and the revision of the entire

time series 1990-2017.

(18)

Concerning the reporting and accounting requirements, under the KP CP2 each Party is required to submit a report, the initial report, to facilitate the calculation of its assigned amount and to demonstrate its capacity to account for its emissions and assigned amount (UNFCC Decision 2/CMP.8). The ratification decision allows a joint initial report of the EU, its Member States and Iceland, to be prepared by the European Commission, and individual initial reports of each Member States and Iceland. In its initial report, Italy describes the national assigned amount as well as the commitment period reserve.

The election of LULUCF activities under Article 3, paragraph 4, of the Kyoto Protocol for the commitment period 2013-2020 is also indicated in the same document; Italy has elected cropland and grazing land management activities.

Emission estimates comprise the seven direct greenhouse gases under the Kyoto Protocol (carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulphur hexafluoride, nitrogen trifluoride) 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 https://unfccc.int/ghg- inventories-annex-i-parties/2020.

ES.2. Summary of national emission and removal related trends

Total greenhouse gas emissions, in CO 2 equivalent, excluding emissions and removals from land use, land use change and forestry, decreased by 17.2% between 1990 and 2018 (from 516 to 428 millions of CO 2

equivalent tons).

The most important greenhouse gas, CO 2 , which accounted for 81.4% of total emissions in CO 2 equivalent in 2018, showed a decrease by 20.5% between 1990 and 2018. CH 4 and N 2 O emissions were equal to 10.1%

and 4.1%, respectively, of the total CO 2 equivalent greenhouse gas emissions in 2018. Both gases showed a decrease from 1990 to 2018, equal to 10.8% and 32.0% for CH 4 and N 2 O, respectively.

Other greenhouse gases, HFCs, PFCs, SF 6 and NF 3 , ranged from 0.01% to 3.9% of total emissions.

Table ES.1 illustrates the national trend of greenhouse gases for 1990-2018, expressed in CO 2 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 2018, of 80.5%.

Emissions from this sector decreased by 18.7% from 1990 to 2018. Substances with decrease rates were CO 2 , whose levels reduced by 18.5% from 1990 to 2018 and accounts for 96.5% of the total in the energy sector, and CH 4 which showed a reduction of 34.4% but its share out of the sectoral total is only 2.2%; N 2 O, also, showed an increase of 0.4% from 1990 to 2018, accounting for 1.3%. Specifically, in terms of total CO 2

equivalent, an increase in emissions was observed in the other sectors, about 5.8%, from 1990 to 2018; in 2018 this sector accounted for 24.2% of total energy sector emissions.

For the industrial processes sector, emissions showed a decrease of 14.2% from 1990 to 2018. Specifically, by substance, CO 2 emissions account for 44.0% and showed a decrease by 48.0%, CH 4 decreased by 65.9%, but it accounts only for 0.1%, while N 2 O, whose levels share 1.9% of total industrial emissions, decreased by 90.6%. 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 mineral and metal production emissions. A considerable increase was observed in F-gases emissions (more than 300%), whose level on total sectoral emissions is 53.9%. 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 years.

For agriculture, emissions refer mainly to CH 4 and N 2 O levels, which account for 63.8% and 34.8% of the sectoral total, respectively; CO 2 , on the other hand, shares only 1.4% of the total. The decrease observed in the total emissions (-13.0%) is mostly due to the decrease of CH 4 emissions from enteric fermentation (- 8.4%), which account for 47.1% of sectoral emissions and to the decrease of N 2 O from agricultural soils (- 17.5%), which accounts for 27.6% of sectoral emissions.

As regards land use, land-use change and forestry, from 1990 to 2018 total removals in CO 2 equivalent considerably increased; CO 2 accounts for almost the total emissions and removals of the sector (98.3%).

Finally, emissions from the waste sector increased by 5.7% from 1990 to 2018, mainly due to an increase in the emissions from solid waste disposal on land (12.3%), which account for 74.9% of waste emissions. The most important greenhouse gas in this sector is CH 4 which accounts for 89.2% of the sectoral emissions and shows an increase of 5.5% from 1990 to 2018. N 2 O emission levels increased by 41.9%, whereas CO 2

decreased by 82.1%; these gases account for 10.3% and 0.5% in the sector, respectively.

Table ES.2 provides an overview of the CO 2 equivalent emission trends by IPCC source category.

Sommario (Italian)

Nel documento “Italian Greenhouse Gas Inventory 1990-2018. National Inventory Report 2020” si descrive la comunicazione annuale italiana dell’inventario delle emissioni dei gas serra in accordo a quanto previsto nell’ambito della Convenzione Quadro sui Cambiamenti Climatici delle Nazioni Unite (UNFCCC), del protocollo di Kyoto. Tale comunicazione è anche trasmessa all’Unione Europea nell’ambito del Meccanismo di Monitoraggio dei Gas Serra.

Ogni Paese che partecipa alla Convenzione, infatti, oltre a fornire annualmente l’inventario nazionale delle emissioni dei gas serra secondo i formati richiesti, deve documentare in un report, il National Inventory Report, la serie storica delle emissioni. La documentazione prevede una spiegazione degli andamenti osservati, una descrizione dell’analisi delle sorgenti principali, key sources, e dell’incertezza ad esse associata, un riferimento alle metodologie di stima e alle fonti dei dati di base e dei fattori di emissione utilizzati per le stime, un’illustrazione del sistema di Quality Assurance/Quality Control a cui è soggetto l’inventario e delle attività di verifica effettuate sui dati.

Il National Inventory Report facilita, inoltre, i processi internazionali di verifica cui le stime di emissione dei gas serra sono sottoposte al fine di esaminarne la rispondenza alle proprietà di trasparenza, consistenza, comparabilità, completezza e accuratezza nella realizzazione, qualità richieste esplicitamente dalla Convenzione suddetta. Nel caso in cui, durante il processo di review, siano identificati eventuali errori nel formato di trasmissione o stime non supportate da adeguata documentazione e giustificazione nella metodologia scelta, il Paese viene invitato ad una revisione delle stime di emissione.

I dati di emissione dei gas-serra, i rapporti National Inventory Report, così come i risultati dei processi di review, sono pubblicati sul sito web del Segretariato della Convenzione sui Cambiamenti Climatici

https://unfccc.int/ghg-inventories-annex-i-parties/2020.

La serie storica nazionale delle emissioni è anche disponibile sul sito web all’indirizzo:

http://www.sinanet.isprambiente.it/it/sia-ispra/serie-storiche-emissioni .

Da un’analisi di sintesi della serie storica dei dati di emissione dal 1990 al 2018, si evidenzia che le

emissioni nazionali totali dei sei gas serra, espresse in CO 2 equivalente, sono diminuite del 17.2% nel 2018

rispetto al 1990. In particolare, le emissioni complessive di CO 2 sono pari all’81.4% del totale e risultano nel

2018 inferiori del 20.5% rispetto al 1990. Le emissioni di metano e di protossido di azoto sono pari a circa il

10.1% e 4.1% del totale, rispettivamente, e presentano andamenti in diminuzione sia per il metano (-10.8%)

che per il protossido di azoto (-32.0%). Gli altri gas serra, HFC, PFC, SF 6 e NF 3, hanno un peso complessivo

sul totale delle emissioni che varia tra lo 0.01% e il 3.9%; le emissioni degli HFC evidenziano una forte

crescita, mentre le emissioni di PFC decrescono e quelle di SF 6 e NF 3 mostrano un incremento. Sebbene tali

variazioni non siano risultate determinanti ai fini del conseguimento degli obiettivi di riduzione delle

emissioni, la significatività del trend degli HFC potrebbe renderli sempre più importanti nei prossimi anni.

1. INTRODUCTION

1.1 Background information on greenhouse gas inventories and climate change

In 1988 the World Meteorological Organisation (WMO) and the United Nations Environment Program (UNEP) established a scientific Intergovernmental Panel on Climate Change (IPCC) in order to evaluate the available scientific information on climate variations, examine the social and economical influence on climate change and formulate suitable strategies for the prevention and the control of climate change.

The first IPCC report in 1990, although considering the high uncertainties in the evaluation of climate change, emphasised the risk of a global warming due to an unbalance in the climate system originated by the increase of anthropogenic emissions of greenhouse gases (GHGs) caused by industrial development and use of fossil fuels. More recently, the scientific knowledge on climate change has firmed up considerably by the IPCC Fourth Assessment Report on global warming which states that “Warming of the climate system is unequivocal (…). There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities (…). Most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations”. Hence the need of reducing those emissions, particularly for the most industrialised countries.

The first initiative was taken by the European Union (EU) at the end of 1990, when the EU adopted the goal of a stabilisation of carbon dioxide emissions by the year 2000 at the level of 1990 and requested Member States to plan and implement initiatives for environmental protection and energy efficiency. The contents of EU statement were the base for the negotiation of the United Nations Framework Convention on Climate Change (UNFCC) which was approved in New York on 9 ^th May 1992 and signed during the summit of the Earth in Rio the Janeiro in June 1992. Parties to the Convention are committed to develop, publish and regularly update national emission inventories of greenhouse gases (GHGs) as well as formulate and implement programmes addressing anthropogenic GHG emissions. Specifically, Italy ratified the convention through law no.65 of 15/1/1994.

On 11/12/1997, Parties to the Convention adopted the Kyoto Protocol, which establishes emission reduction objectives for Annex B Parties (i.e. industrialised countries and countries with economy in transition) in the period 2008-2012. In particular, the European Union as a whole was 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, established a reduction objective of 6.5% in the commitment period, in comparison with the base 1990 levels.

Italy ratified the Kyoto Protocol on 1 ^st June 2002 through law no.120 of 01/06/2002. The ratification law prescribes also the preparation of a National Action Plan to reduce greenhouse gas emission, which was adopted by the Interministerial Committee for Economic Planning (CIPE) on 19 ^th December 2002 (deliberation n. 123 of 19/12/2002). The Kyoto Protocol finally entered into force on 16 ^th February 2005.

The first commitment period ended in 2012, with an extension, for fulfilling commitments, to 18 ^th November 2015, the so called true-up period. The evaluation of the Kyoto Protocol, together with the commitments fulfilled by each Party, has been finalized by the UNFCCC Secretariat.

A new global agreement was reached in Paris in December 2015, for the period after 2020. The agreement

aims to strengthen the global response to the treat of climate change by holding the increase in the global

temperature to well below 2°C above pre-industrial levels and to pursue efforts to limit the temperature

increase to 1.5 °C above pre-industrial levels, recognizing that this would significantly reduce the risks and

impact of climate change. In order to achieve this long-term temperature goal, Parties aim to reach global

peaking of GHG emissions as soon as possible and undertake rapid reductions so as to achieve a balance

between anthropogenic emissions by sources and removals by sinks in the second half of this century. Each

Party shall prepare, communicate and maintain successive nationally determined contributions that it intends

to achieve. On 5 October 2016, the threshold for entry into force of the Paris Agreement was achieved (at

least 55 Parties to the Convention accounting in total for at least an estimated 55 percent of the total global

greenhouse gas emissions, where “total global greenhouse gas emissions” means the most up-to-date amount

communicated on or before the date of adoption of the Agreement). The Paris Agreement entered into force

on 4 November 2016.

PREMESSA

Nell’ambito degli strumenti e delle politiche per fronteggiare i cambiamenti climatici, un ruolo fondamentale è svolto dal monitoraggio delle emissioni dei gas-serra.

In più, come è previsto dalla Convenzione-quadro sui cambiamenti climatici per tutti i Paesi industrializzati, l’ISPRA documenta in uno specifico rapporto, il National Inventory Report, le metodologie di stima utilizzate, unitamente ad una spiegazione degli andamenti osservati.

Nonostante i progressi compiuti, l’attività di preparazione degli inventari affronta continuamente nuove sfide

legate alla necessità di considerare nuove sorgenti e nuovi inquinanti e di armonizzare gli inventari prodotti

per diverse finalità di policy. Il contesto internazionale al quale fa riferimento la preparazione dell’inventario

nazionale costituisce una garanzia di qualità dei dati, per l’autorevolezza dei riferimenti metodologici,

l’efficacia del processo internazionale di review e la flessibilità nell’adattamento alle nuove circostanze.
