    Abstract

    The indicator includes the emission allowances generated by installations covered by the EU Emissions Trading System (EU ETS), established under Directive 2003/87/EC, and the greenhouse gas emissions from all sectors not included in the ETS scope—namely small- and medium-scale industry, transport, residential and commercial buildings, agriculture, and waste. These are regulated under Decision No. 406/2009/EC (Effort Sharing Decision, ESD) up to 2020, and by the Effort Sharing Regulation (EU) 2018/842 (ESR) from 2021 onward. While non-ETS sector emissions in 2020 remained below the target threshold of 37 MtCO₂eq, in 2022 they exceeded the allowable limit by 5.5 MtCO₂eq, indicating a deviation from the reduction trajectory required to meet ESR targets.

    Description

    The indicator includes the emission allowances up to 2020 generated by installations covered under the EU Emissions Trading System (EU ETS), established by Directive 2003/87/EC, as well as the greenhouse gas emissions from all sectors not included under the ETS scope—specifically small- and medium-sized industry, transport, buildings (residential and commercial), agriculture, and waste. These non-ETS sector emissions are regulated under the Effort Sharing Decision (Decision No. 406/2009/EC) up to 2020, and from 2021 onwards, by the Effort Sharing Regulation (EU) 2018/842 (ESR).

    Purpose

    Monitoring the emissions trajectory of large industrial installations under the EU Emissions Trading System (EU ETS) and tracking national targets for emissions from sectors not covered by the ETS—such as transport, residential and commercial buildings, agriculture, waste, and small to medium-sized industry—is essential for compliance with climate obligations. These non-ETS sector emissions were governed by the Effort Sharing Decision (Decision No. 406/2009/EC) up to 2020, and are currently regulated under the Effort Sharing Regulation (EU) 2018/842 (ESR) from 2021 onward.

    The EU Emissions Trading System (EU ETS), Effort Sharing Regulation, and Related Legislative Developments in the Context of the European Green Deal

    Directive 2009/29/EC amended Directive 2003/87/EC to enhance and expand the EU Emissions Trading System (EU ETS), establishing a single EU-wide emissions cap from 2013 onward. Under this directive, the total quantity of emission allowances available is reduced annually by 1.74%, leading to a 21% decrease in 2020 compared to 2005 levels. The scope of the EU ETS was also expanded to include additional greenhouse gases (GHGs) and economic activities.

    The Effort Sharing Decision (ESD), Decision No. 406/2009/EC, assigned binding national GHG reduction targets for sectors not covered by the ETS—such as transport, buildings, agriculture, waste, and small industries—for the period 2013–2020. Italy was allocated a 13% reduction target by 2020 relative to 2005 levels, with mandatory annual compliance targets during the commitment period.

    Additional legislative updates include:

    Regulation (EU) 2017/2392, which amended Directive 2003/87/EC to preserve the scope of aviation activities under the ETS and to prepare for the global market-based measure under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) from 2021 onwards.

    Directive (EU) 2018/410, which introduced further revisions to Directive 2003/87/EC, aiming to improve cost-effective emissions reductions and incentivize low-carbon investments. It also aligned with Decision (EU) 2015/1814 concerning the Market Stability Reserve.

    In alignment with the European Green Deal, the EU updated its 2030 climate and energy policy framework, committing to:

    A 55% net reduction in GHG emissions by 2030 relative to 1990,

    A minimum 42.5% share of renewable energy in gross final energy consumption (with a political aim of reaching 45%, as per the provisional agreement of 2023),

    An improvement in energy efficiency by at least 36% in final energy consumption and 39% in primary energy consumption compared to the projected baseline (based on the PRIMES 2007 model).

    To achieve these targets, Directive (EU) 2023/959 reformed and extended the EU ETS to new sectors, including road transport and buildings. By 2030:

    ETS-covered sectors must reduce emissions by 62% compared to 2005 levels,

    Non-ETS sectors (under the Effort Sharing Regulation – ESR, Regulation (EU) 2018/842) are required to achieve a 40% reduction at the EU level, with binding national targets.

    For Italy, the ESR target is a 43.7% reduction in emissions by 2030 relative to 2005. Annual targets for 2021–2030 are outlined in Implementing Decision (EU) 2020/2126, which allocates the Annual Emission Allocations (AEAs) per Member State.

    Processing methodology

    For the calculation of the 2020 target for the ESD sectors (regulated by the Effort Sharing Decision), the greenhouse gas emissions for 2005 were set based on the emissions recorded in the 2005 inventory published in 2011 (582.1 Mt CO2eq). From this value, the CO2 emissions from civil aviation (2.2 Mt CO2), emissions from ETS sectors (226 Mt CO2eq), and emissions from plants that entered the ETS system in the 2008-2012 period (5.9 Mt CO2eq) must be subtracted. The resulting value is then subject to a -13% reduction target for 2020, with a linear reduction from 2013 for the annual targets. The emissions calculated for 2005 for the purpose of assigning targets are equal to 348 Mt CO2eq. The calculation of annual allocations from 2013 to 2020 also involves subtracting the contribution from plants that entered the ETS system from 2013 onwards. The level of annual emissions from the ESD sectors is calculated by subtracting emissions from ETS sectors, CO2 emissions from domestic aviation, and NF3 emissions from total greenhouse gas emissions. From 2021 onwards, the level of annual emissions from the ESR sectors (regulated by the Effort Sharing Regulation) is calculated by subtracting emissions from ETS sectors and CO2 emissions from domestic aviation from total greenhouse gas emissions.

    Qualità dell'informazione

    The information regarding greenhouse gas emissions is relevant for ensuring compliance with the emission reduction targets set by Decision 406/2009/EC (Effort Sharing Decision, ESD) until 2020 and by Regulation 2018/842 (Effort Sharing Regulation, ESR) from 2021 onwards. The estimates are calculated in accordance with the transparency, accuracy, consistency, comparability, and completeness requirements established by the methodology defined by the IPCC.

    State assessment/description

    Le emissioni dei settori ETS, per le quali non sono previsti obiettivi nazionali, nel 2022 sono state di 136,3 MtCO2eq, mentre le emissioni dei settori ESR sono state di 274,3 MtCO2eq, con un incremento rispetto al 2021 del 3,7% per ETS e un decremento dell’1,4% per ESR. Per i settori ESR le quote assegnate nel 2022 sono 268,8 MtCO2eq, pertanto le emissioni da essi non sono in linea con quanto richiesto dall’obiettivo, poiché superiori 5,5 MtCO2eq. (Tabella 1 e Figura 1).

    Trend assessment/description

    In 2022, emissions from the ETS sectors showed a 39.7% reduction compared to 2005 levels. Over the same period, emissions from the Effort Sharing sectors decreased by 24.2% (Table 1, Figure 1). This trend is partly due to policies aimed at reducing the impacts of industrial sectors and improving efficiency in the civil sector, as well as the economic crisis that severely affected certain sectors responsible for high levels of greenhouse gas emissions. Additionally, 2020 emissions were heavily influenced by lockdown measures that halted economic activities to contain the SARS-CoV-2 pandemic, while 2021 saw a recovery, followed by another decline in 2022.

    Comments

    The targets set for the ESD sectors in 2020 were largely achieved, while in 2021 and 2022, there was a significant overshoot of the emission limit established for the 2021-2030 period (Table 1, Figure 1). The indicator highlights the national progress made towards a low-carbon economy, showing a reduction in emissions from 2005. However, the country needs to increase its efforts to meet the targets set for the ESR sectors during the 2021-2030 period.
