Snam's choices in a changing world

I	In line with last year's first edition,
the "2023 Sustainability Profile" aims
	to outline Snam's strategy in regards

to the sustainability challenges the Group faces in the context of an increasingly complex and multifactorial energy, geopolitical, economic, environmental and social scenar- io. But it also serves another purpose: the publication of this report marks the relaunch of Snam's commitment to the area under the auspices of its new ambition, geared towards developing "energy infrastructure for a sustainable future".

We at Snam, strengthened by our positioning at European level as the only system operator active along the entire value chain - from transportation to dispatching, from storage to regasification - aim to position ourselves as a point of reference and example of sustainability in the field of the construction and management of energy infrastructures in Italy and Europe.

If 2022 was a turning point for the global energy system, then the most recent year - although continuing to highlight the energy market's volatility and the fragility of the social and economic equilibrium connected to it - have demonstrated the positive effects of the wide-ranging actions that Snam has undertaken. It has also shown the strategic importance of the Group's short, medium and long-term objectives, which the new Strategic Plan to 2027 has extended with the addition of new challenging targets. These range from reaching Net Zero by 2050 for the entire value chain to achieving a positive

SUSTAINABILITY PROFILE

impact by 2027 in regards to the ecosystems affected by the presence of the managed in- frastructures.

Despite the unstable context, emphasised by the exacerbation of the multiple challenges on the geopolitical, economic, environmental and social fronts that the international community faces on a daily basis, 2023 was a period of great operational achievements for Snam. The first part of the year saw the arrival and commissioning at Piombino of the first of the two FSRUs purchased to accelerate the country's decoupling from Rus- sian gas supplies. In the Ravenna area, in par- allel, work has started to accommodate the second regasification vessel, which will be in operation by the first half of 2025. Filled in record time, the storage facilities - due partly to counterflow services - ensured security of supply and flexibility for shippers, while the positive environmental impact assessments secured during the year will allow several sites to operate overpressure, further boosting the system's resilience.

In other words, 2023 represented a turning point for Snam, well summed up by its "am- bition": to be providers of "energy infrastructure for a sustainable future", so that the development of our traditional infrastructure itself becomes an added value for energy transition businesses. We continue to pursue all of the Group's objectives, from those related to energy security to those related to decarbonisation and the transition, in the joint interest of Italy and Europe and, above all, with a view to building cooperation and working alongside all our stakeholders, public or private, and with people always at the core - whether they work for Snam or belong to the areas we serve.

Sustainable strategy

In all its activities, in Italy and abroad, Snam pursues a sustainable and socially responsible growth model, aimed at creating value for the company and for the communities in which it operates.

SUSTAINABILITY PROFILE

The sustainability framework is divided into 7 strategic pillars. For each pillar, the Group has defined a clear ambition with a

2030 outlook:

Biodiversity and

Carbon 34 regeneration Neutrality

Sustainability strategy

Sustainability is profoundly integrated into the new 2023-2027 Strategic Plan, in which it takes on the role of an enabling and wide-ranging strategic lever to guide the Group in its investment decisions, and day- to-day activities, as well as in the development of corporate businesses, contributing to long-term value creation.

To this end, Snam has defined a sustainability framework which, integrated into the Group's strategy, reflects its goal of achieving a fair and balanced transition to a low-carbon economy, based on multi-mole-

cule infrastructure, decarbonisation, biodi- versity, innovation and digitalisation, while also considerate of Snam's people and local communities.

On the one hand, Snam intends to enable a safe and credible energy transition, directing huge investments in the creation of future -proof infrastructures; on the other, it wants to be a company whose approach to sustainability is as comprehensive as possi- ble, ensuring fair, inclusive and safe working conditions for its employees, collaborating with local communities and actively working to reduce emissions.

the Plan period, net of public funding. Part of this will go to the Ravenna CCS project, operated as a 50:50 joint venture with Eni, under which the permanent storage of 16 million tonnes of CO2 per year is expected to be achieved by 2030, thereby making an important contribution to decarbonising "hard- to-abate" industries.

Together with CCS, hydrogen represents an option for achieving decarbonisation targets and realising the energy transition. Snam works on this across three areas: 1) consolidating gas transportation and storage assets that are also hydrogen ready, 2) encouraging the districting of production and consumption through the hydrogen valley mechanism and 3) working with R&D towards enabling technologies.

All this follows in the wake of a long-term strategy whose main objectives, which converge with energy security aims, include delivery of the so-called SoutH2 Corridor, one of the corridors identified by the European Union for importing green hydrogen. Snam is working on this in collaboration with other European TSOs, with the aim of transporting green hydrogen produced in the southern

Energy efficiency

Through Renovit, an Italian platform launched by Snam and CDP Equity, certified as a B Corp and having become a Benefit Company in 2023, to promote the energy efficiency of companies, condominiums, the tertiary sector and public administra- tion, Snam plays a leading role in the energy services sector, having developed over the years a solid basis of energy performance contracts and energy requalification projects for the various stakeholders indicated. Specifically, in 2023 Renovit avoided around 57,000 tonnes of CO2 emissions and, with 300 million euros of investments to 2027, will further extend its portfolio of customers in the public and industrial sectors with the aim of exceeding 130,000 tonnes of avoided emissions over the plan's timeframe.

Furthermore, thanks to the investment plan mentioned above, Snam aims to reach a value of registered contracts by 2027 worth approximately 3 billion euros, of which more than 60% in the public sector and with long- term contracts.

Biomethane

Through its subsidiary Bioenerys, Snam plays a dual role in the biomethane business: on the one hand, it facilitates the interconnection of plants to the grid; on the other, it develops and builds plants for the treatment of municipal solid waste and agricultural raw materials.

In 2023, Bioenerys had biomethane and biogas capacity of around 41MW - 16MW in the waste sector and 25MW in the agricultural sector, and intends to reach a total capacity of 80MW and production of approximately 135 million cubic metres per year by 2027.

In 2023, Snam avoided the emission of 45.9

thousand tonnes of CO2; its target is to exceed 300 thousand by 2027.

Hydrogen and CCS

Established in 2022, the Decarbonisation Projects function manages Snam's Carbon Capture and Storage (CCS) and hydrogen projects, with the aim of accelerating their development and deployment as key levers in ensuring the achievement of European and global decarbonisation goals.

Snam intends to take the lead in the development of the infrastructure for transporting and storing CO2, for which about 350 million euros of investment is earmarked over

Mediterranean to Italy and Central Europe, potentially covering 40% of the import target set by the REPower EU Plan from 2030.

N.B. the data refer to the entire Snam Group, unless otherwise indicated. (1)Emissions avoided through the activities related to the biomethane and energy efficiency businesses. It calculates the CO2e emissions avoided by Renovit's energy saving measures on residential, industrial, tertiary and public administration buildings and the CO2e emissions avoided by using biomethane produced by Bioenerys instead of fossil gas. The latter contribution is evaluated by multiplying the biomethane volumes (scm) by its lower heating value (LHV or PCI, GJ/1000 scm) and the emission factor of natural fossil gas (from Ispra, tCO2/TJ), indicating the emissions that would have occurred with the use of fossil gas (compared to the use of biomethane). (2)Biomethane production by Bioenerys. The figure corresponds to gross biomethane production (compared to net production used in previous years). The scope of the indicator for 2023 refers to the following companies: Bioenerys Ambiente S.r.l., Bioenerys Agri S.r.l. and Iniziative Biometano (the latter removed from the portfolio as of October 2023). 3) Cumulative figure for the period 2023-2027 net of contributions, dilution and goodwill due to Eni. CapEx invested according to i) the business plan agreed between Snam and Eni, referring to the development of the storage facilities of the Ravenna CCS Project during phases 1+2 (experimental phase and industrial phase), and ii) the business plan developed solely by Snam, referring to the development of the onshore transportation system of Ravenna CCS via pipeline.

N.B. the data refer to the entire Snam Group, unless otherwise indicated. (1)The target was renamed. In previous years it was "Percentage level of reliability of gas supply". The perimeter of the target refers to Snam Rete Gas. The target is calculated as: (Volume of gas injected into the transmission network - Allocated transportation capacity made unavailable) / Volume of gas injected into the transmission network. (2) Certification of the suitability of existing network materials for the transportation of H2, in accordance with the applicable requirements given in report P0027355-1-H2, defined according to the methodology described in RINA document GUI.16 'Guide for Technology Qualification Processes' dated 15.12.2016 and based on ASME standard B31.12 'Hydrogen Piping and Pipelines' (2019 edition).

Transportation

Snam transports natural gas throughout Italy via more than 33,000 km of pipelines. Managed by its subsidiary Snam Rete Gas, these provide widespread coverage of the country, ensuring continuity of supply in line with demand across the whole year and leveraging pipeline transportation, which is more efficient and reliable than road trans- port, as well as having less impact on the en- vironment.

The company has 13 compressor plants (which will rise to 14 by 2026 with the new Sulmona power plant) located across the national network that serve to maintain constant gas pressure along its entire route to ensure the regular flow of gas. In addition, it has 48 maintenance centres, 8 districts and a dispatching centre, which controls and oversees the transportation network remotely using a data-driven and risk-based approach, monitoring the health of the assets and scheduling their maintenance on a predictive basis.

SUSTAINABILITY PROFILE

Storage

Through its subsidiary Stogit, Snam manages 9 storage plants, which act in synergy with the other transportation and regasification infrastructures of the Group, contributing to the flexibility and redundancy of the national energy system and promoting the continuity of gas supplies in our country, in any day of the year.

Indeed, storage activity is essential to manage fluctuations in demand linked to seasonal dynamics, representing a strategic solution against unforeseen events or unexpected increases in demand in response to particular weather conditions. In this way, it also ensures the availability of the necessary gas quantities in order to compensate for possible interruptions or reductions in non-European supplies, or to overcome temporary crises in the gas system.

In fact, the storage system stores gas during periods of lower demand (typically in the summer period) and then delivers it at times of peak demand or in the event of a shortage or momentary interruption of imports (typi- cally in the winter period).

In the changing world, Snam's choices

SUSTAINABILITY PROFILE

Regasification

Through its subsidiaries GNL Italia and FSRU Italia, Snam is also involved in the regasi- fication of LNG, i.e. natural gas that, once extracted, is liquefied through a specific cooling process that significantly reduces its volume, ensuring easier transportation by LNG carriers.

Built in 1971, the terminal at Panigaglia (La Spezia) was the first operational regasifi- cation plant in Italy, consisting of 2 storage tanks of 50,000 cubic metres each, vaporisation plants and a landing stage for LNG car- riers. With a view to promoting greater security and diversification of energy supplies, Snam has invested in floating regasification units or FSRUs (Floating Storage and Regasi- fication Units) since 2022.

Specifically, the Golar Tundra floating unit (Piombino), purchased in May 2022, officially entered into commercial operation in July 2023 with the arrival of the first LNG carrier, while the BW Singapore, purchased in De- cember 2023 and expected by the end of the year off the coast of Ravenna, is scheduled to enter into operation in the first half of 2025. Both floating regasification terminals have a maximum storage capacity of about 170 thousand cubic metres of liquefied natural gas and a nominal continuous regasifica- tion capacity of about 5 billion cubic metres per year.

Within the framework of the 2023-2027 Strategic Plan, Snam intends to invest in the connection works between the FSRUs and the network, in the infrastructure investments required for the relocation of the FSRU Go- lar Tundra, and in the commissioning of BW Singapore.

FSRUs are vessels located close to a port area, either at the quayside or offshore, which receive liquefied natural gas in order to store, regasify and then feed it into the national gas transportation network. They are recognised as being safe and having a low environmental impact.

LNG and sustainable mobility

The instability of gas prices, combined with the need to pursue energy independence for Italy, have led Snam to fully exploit the versatility of some of its assets. Through Green- ture, set up in 2017 to drive decarbonisation in mobility via the development of a network of C-LNG (Compressed and Liquefied Natural Gas) roadside refuelling stations, Snam has gradually extended the scope of its commitment to sustainable transport, and in 2022/2023 began creating midstream infrastructure for heavy transport in the shipping and rail sectors. Moreover, by developing infrastructure to support the use of Bio C-LNG and hydrogen, Greenture also intends to foster the energy transition of off-grid industrial and civil users, confirming Snam as a key infrastructure operator for small-scale projects.

As part of the 2023-2027 Strategic Plan, Snam expects to continue developing small- scale LNG infrastructure and expanding the networks of LNG and bio-LNG stations, and, in the future, hydrogen stations; it also expects to adapt regasification terminals to allow them to support small-scale LNG activities and construct micro-liquefaction plants and coastal storage facilities.
