Natural Capital

What is the Natural Capital for A2A?

The Natural Capital is the set of all processes and environmental resources contributing towards the production of services offered by the company.

A2A da sempre attenta all'ambiente

One of the commitments of the A2A Group has always been to combine the quality of services and economic development with environmental protection. In 2018 the CO2 emissions are decreased by 7%, compared to 2017, due to a lower use of fossil fuels. At the same time, the production of energy from renewable sources increased, thus reducing the Group's emission factor (-10% compared to 2017). In addition, NOx, SO2 and dust emissions from all waste-to-energy plants were well below the legal limits set for these pollutants.

In 2018, avoided CO2 emissions amounted to 2.8 million tonnes and energy savings exceeded 1 million toe (tonnes of oil equivalent) and a great contribution made by the Group's ESCO companies (Energy Solutions and Linea Green), which in 2018 contributed to avoiding almost 2 million tonnes of CO2 by means of the interventions carried out.

Brescia towards decarbonisation

In order to improve the environmental aspect of emissions into the atmosphere, some interventions are planned on the district heating system of Brescia, which will make it possible to ensure the need for heat to users without resorting to coal combustion, by the end of 2022.

The implementation phases consist in:

  • the construction of heated water storage tanks (see page 72) to reduce heat requirements at peak loads
  • the construction of a photovoltaic system at the Lamarmora power plant to reduce energy withdrawals for self-consumption
  • the expansion of the DeNOx  of the Lamarmora power plant to halve emissions up to 80 mg/Nm3  to ensure optimal operation until 2022
  • the recovery of heat from industrial sources
  • the implementation of heat recovery technology from flue gas cleaning on all 3 lines of the wasteto-energy plant.

The expected results in terms of impacts on the atmosphere are significant: a 50% reduction in nitrogen oxides, a 40% reduction in dust and a 90% reduction in sulphur oxides; a 105,000-tonne saving in CO2 emissions per year; regarding fossil fuel consumption, a reduction of 15,000 toe/year will be achieved.
