We are reducing our footprint

Combating climate change

The governance of this area is overseen by the Board of Directors through the company’s Top Management and the activity of the Committees, thanks to the Risk Management and Control System, which is implemented with the full involvement of the Group’s managers and integrates into its risk/opportunity analyses also the risks arising from climate change and other sustainability issues.

The most important objectives we set ourselves are the following:

promoting actions to mitigate climate-altering gas emissions – CO2 emissions in particular – such as the marked increase in energy production from renewable sources; increasing efficiency of internal energy end-uses; using G.O. (Guarantee of Origin) certified energy; pushing towards electric mobility, offering our customers green energy and 0% CO2 gas, with G.O. certified energy from renewable sources and the offsetting of gas-related emissions through the purchase of certified carbon credits (VER: Verified Emission Reduction);
developing our infrastructures with interventions to increase their adaptability to climate change.

For many years, we have taken part in the CDP questionnaire, monitoring and publishing information on our emissions and the initiatives taken to reduce them. In June 2022, downstream of a project completed in 2021 aimed at identifying, selecting and investigating the most significant climate risks for the main Group companies, the first Acea Group 2021 climate-related disclosure was published in accordance with the recommendations of the Task Force on Climate-related Financial Disclosure. This activity led us to carry out our first climate scenario analyses - involving the Group’s main companies - and allowed us to develop our knowledge of the different aspects associated with climate change and refine our ability to manage risks (both physical and transition) and related opportunities. We therefore decided to continue the project, expanding the analysis perimeter and involving a greater number of Group companies in identifying the related physical and transition risks, and some key functions of the Parent during the phase of prioritising the risks identified.

Carbon Disclosure Project

Again in 2022, Acea participated in the Carbon Disclosure Project (CDP), obtaining a B rating, which positions the company in the Management class. CDP is an independent non-profit organisation that offers investors a system for measuring company policies and performances in connection with Climate Change. The rating, which is established on a scale from D (minimum) to A (maximum), is based on the assessment of actions undertaken in this area. Acea’s good positioning acknowledges its commitment to fighting climate change through a sustainable business model.

Protection of the community

We consider protection of the community to mean a reduction of impacts on the natural environment generated by operating processes and infrastructures, the conservation of water resources and the commitment to safeguarding biodiversity. With this in mind, we operate according to environmental management systems and perform a careful and continual monitoring of meaningful indicators.

Springs and protected areas

Rome is, today one of the few metropoles in the world, that can boast a water resource of excellent quality right from its source.

We take the utmost care to safeguard our water resource.
Just in the territory managed by Acea Ato 2 there are 14 of our main supply sources, located in vast fully protected areas, which we are committed to preserving.

The procurement system in the Lazio area

Data as at 31 December 2022

Central Lazio (ATO 2)

Southern Lazio (ATO 5)

14 main supply sources, all "fully" protected
13,152 km of drinking water network, including aqueducts
Capacity of over 21,000 litres per second

80 procurement sources, of which 75 are active (comprising springs and wells)
6,181 km of drinking water distribution network, including aqueducts

From an efficiency and continual improvement perspective, in recent years we have integrated our environmental monitoring and surveillance operations with satellite systems, which enable us to more precisely identify the areas subject to morphological anomalies by comparing the images captured from space several months apart. In 2022, our upgrading of the said control system via the internalisation of our change detection process, alongside additional inspections, allowed us to detect 63 situations of abuse.

The impact of energy structures on birdlife

Protection of the natural environment is also linked to the energy distribution business. Areti, the Group Company that manages this business, in collaboration with the competent authorities, is committed to mitigating the impact on birdlife of the high and medium voltage overhead lines. Thanks also to the transformation and modernisation of the distribution network, the territorial protection index, calculated as a percentage of the underground high voltage (HV) network of the total HV lines in operation (overhead and underground), has improved and, in 2022, amounted to 49.3% (in 2021, the percentage was 47%).

Efficient use of resources

Acea's efficient use of natural resources translates into various areas of action: the reduction of leaks in the water and energy networks, improved efficiency in internal use the raising of awareness among users and residents and promotion of a circular economy with regard to waste.

Reduction of leaks and improved efficiency

Water

The Group’s main water companies carry out a constant monitoring of distribution network efficiency and leak detection, by applying a methodology based on water districts, making it possible to optimise the operating pressures and reduce the lost volumes. Overall, in December 2021 Acea Ato 2 created 581 measurement districts of a total 11,500 km of distribution network. The activity consisted of surveys, flow and pressure measurements, map production, user analysis and water balancing, creation of measurement stations, installation of shut-off and regulation devices, mathematical modelling and leak detection activities. Acea Ato 5 also continued its analysis of the network structures, the creation of water districts and remotely controlled flow meters also functional to leak detection and recovery activities; in 2022, the new districts created totalled 100 and concerned 856 km of network. Gori continued to pursue a structured path of activities to optimise the water network in various municipalities. The actions taken provided for distinct phases: supplementary surveying, districting, modelling and execution of pressure control and leak detection interventions. AdF carried out an intense activity of systematic leak detection on its water networks, during the year inspecting around 2,500 km of distribution network, and an additional 430 km of network were then monitored as part of the districting operation. Lastly, Gesesa continued to work on the replacement of some pipelines, implementation of remote monitoring, application of a water leak reduction system and reduction of the operating pressures in the network.

Overall, thanks to the activities put in place by the companies, in 2022 the volumes of water resource lost were down by 6% compared to 2021 and by 14% compared to 2020.

Energy

Management of the Rome and Formello electricity distribution network is characterised by a continuous improvement in performances, with particular attention to energy efficiency. The initiatives to reduce grid losses include the reclassification of medium voltage levels from 8.4 kV to 20 kV and the installation of MV/LV transformers with very low losses; in 2022, the electricity distribution network losses came to around 6,5% of the total energy fed into the grids, in line with the previous year.
The initiatives undertaken were also aimed at improving the resilience of the networks and optimising their management, in the name of technological innovation. To this effect, steady progress is being made as regards the activities envisaged in the Plan to modernise the high-voltage electricity distribution grid (150kV), with the demolition of lines and removal of pylons, the completion or commencement of network reconfiguration and optimisation interventions, leading to a lower environmental impact and an improvement in the service.
As regards energy generation, having completed the modernisation and efficiency enhancement of the hydroelectric power plants, in 2022 Acea concluded its revamping of the Sant’Angelo power station, aimed at optimising the use of available water resources, with the same conditions of installed power licenced under concession.
Moreover, Acea will continue to increase its production of electricity from renewable sources, thereby contributing to the ecological transition.

Cyber Security: innovation and risk analysis

We are committed to overseeing the Group’s IT security, guaranteeing the correct working of all our infrastructures. The Cyber Security Unit is working on the progressive enhancement of skills, technological innovation, processes and organisation, performing a reference role for the security of the Group’s operating companies. More specifically, in 2022 a new strategy, objectives, technologies and processes were defined in the IT, OT and IoT areas. Also going ahead are the cyber risk analysis programme as regards all Acea services, for the identification, measurement and management of risk arising from cyber threats, and the Vulnerability Management Programme, aimed at identifying and mitigating vulnerability. Moreover, we are engaged in awareness and training campaigns for all our people, with a view to enhancing individual competences. Lastly, we have decided to subscribe to the European Programme ECHO (European network of Cybersecurity centres and competence Hub for Innovation and Operations), for the creation of a European network of cybersecurity competence centres, as well as the H2020 ATENA Project concerned with security and resilience of digital infrastructures.

Waste recovery and circular economy

We consider our environmental services business, and waste management in particular, to be a sector with great potential.
We are currently working on waste recovery projects with various applications:

we deal with waste treatment and material recovery
we convert waste into energy via a waste-to-energy process, achieving a notable reduction in the percentage of outgoing waste (24% of all incoming waste);
we generate biogas, at the waste treatment plant in Orvieto and the other composting sites, with an overall energy output of 36.3 GWh;
we treat liquid waste
we produce high quality compost, totalling 36,976 tons in 2022.

The Acea Smart Comp project

Thanks also to the support from the Tuscia University and Enea, we are continuing our “Smart Comp” project, which sees us engaged in developing the effective zero kilometre waste management model based on a widespread and distributed network of mini-plants for organic fraction treatment. The evolution of the project, which allows the local transformation of wet waste into compost, via a process which in about 90 days produces ready-to-use fertiliser, has led the Company to become Organic Waste Free and to patent the control system for electric composters. We are working on applying the solution to the new circular communities and smart apartment buildings concept: for this purpose, we have launched experimental pilot projects for various types of users, including military bases, universities and local markets.

The advantages of the project are both economic – in terms of lower waste collection and treatment costs – and environmental – in view of the containment of CO2 emissions associated with transport logistics.
