incidents of high and critical severity monitored

Efficient management of Group infrastructures


  • Completed works on two new treatment plants in the Brescia municipalities: San Paolo and Offlaga (for a total of 14,000 equivalent inhabitants)
  • Start of the sites for the construction of the new plants for the treatment of OFMSW (Organic Fraction of Municipal Solid Waste) and the production of compost and biomethane at Lacchiarella (Mi) and Cavaglià (BI)
  • Acquisition of the Group's first wind farm (8,2 MW), located in Campania, and start of the procedures to authorize the installation of electrochemical storage systems for a portfolio of projects of around 60 MW to be built at sites it owns
  • A2A Calore e Servizi entered into an agreement with the REA DALMINE industrial plant, owned by Greenthesis Group, which provides for a 50% increase in the heat available in the district heating network of the city of Bergamo  
  • Completed, on the Milan electricity network, the plan to improve the resilience of electricity grids against the extreme events related to the climate change replacing more than 10,000 joints

total volume of water released for Minimum Vital Flow compared to 2019

Water used per unit of Energy produced (m3/MWh)


  • Achieved a reduction of the water consumption by the the companies in the A2A Group thanks to the recovery of process water and rainwater, the latter for the irrigation of green areas, the filling of fire fighting tanks and the recycling of washing water
  • Made interventions to recover and save water at the Piacenza power plant: capture of water used by the cooling systems of the offices, initially channelled to the drain, now instead recovered in the industrial water cycle; installation of solenoid valves to prevent the flow of water during the inactivity phases of the plant
  • Established a greater level of control over water withdrawals in water-stressed areas, impacted by: scarcity of fresh water available; possible complexity in water extraction and distribution to users; water quality characteristics
  • Start of the Aquarius Project for early detection of water leaks using a widespread network of non invasive sensors (capable of detecting the "noise" of a leak escaping from a pipe) and a dedicated processing platform

  • Completed work on the new treatment plant in the Brescia municipality of San Paolo, capable of serving 6,000 equivalent inhabitants
  • Completed work on the Offlaga treatment plants with a nominal capacity of 8,000 equivalent inhabitants
  • Upgraded the the San Gervasio treatment plant through the installation of a new modular treatment line with MBR technology with a capacity of 1,200 equivalent inhabitants
  • Start of work on the construction of the Valtrompia district treatment plant, which will make it possible to overcome the problem of European infringements for the municipalities in the area that are not covered by the treatment service

Performance 2020


sites analyzed


sites with potential interference with the system of protected areas


sites where it's possible to carry out an intervention because they correspond to areas subject to protection, of high ecological value and with the possibility of intervention to improve the ecosystems


  • Concluded the analyses of the potential interference of the A2A Group's activities with the system of protected areas, namely with sites belonging to the Natura 2000 Network, IBA (Important Bird and Biodiversity Area) areas
  • Developed a "relevance index" to measure the degree of potential interference that the activities could have on the ecosystems, due to the proximity and peculiarities of the habitats present in the protected areas

Group sites and activities with interference on protected areas

  number of directly interfering sites/networks activities performed interfering area surface/interfering network stretch length type of protected areas

Final destination of municipal waste collected


  • Created the "environmental meter" in Milan that quantifies the positive environmental impact of differentiated waste collection and recycling and recovery activities
  • Assessment of the circularity of the integrated water service as a part of the "RIECCO" project promoted in collaboration with the Sant'Anna School of Advanced Studies of Pisa 
  • Signed a Memorandum of Understanding with Suez, aimed at creating a player of excellence for the management of waste from the Italian production and industrial system
