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.


Circular Economy: the A2A’s "modus operandi"

A2A has always been careful to minimize the use of virgin material. The Environment BU plays a fundamental role in this area: through the collection, transport and treatment services for urban and special waste, it carries out, with appropriate treatments, the material to be returned to the cycle thus reducing the demand for virgin raw materials. In 2020, for example, the amount of plastic waste recovered increased by 73% compared to 2019. This made it possible to save 50,000 m3 of water and 47,000 tonnes of carbon dioxide, compared to the production of a similar virgin raw material from oil. We have thus reached the target of 1 million tonnes of waste treated in our treatment and recovery plants.

But for A2A, the approach to circularity is not resolved solely with the waste management sector, in Networks & District Heating BU, prevention is implemented through the evaluation of material removed from network maintenance and the consequent reuse of materials that are still suitable and functional. In the Generation and Trading BU with the production of gypsums – flue gas desulphurization at the Monfalcone plant – with chemical and physical characteristics required by the technical standards of the sector – to be used directly in cement plants as raw materials.

The Energy Transition: the A2A’s path

For several years A2A has been engaged in the transition from fossil fuels to renewable sources. The Group is implementing several initiatives to contribute to this transition, focusing mainly on the growth of renewables and supporting the flexibility needs of the electricity system. In 2020, the Group's overall electricity production saw a contribution from renewable sources of 33% (+ 6 p.p compared to 2019), thanks in part to the acquisition of biomass-fired plants and the simultaneous reduction in the use of coal, which was definitively abandoned for cogeneration production and will be eliminated in the coming years.

(*)Excluding the share of renewable production from waste

In 2020 CO2 emissions decreased due to lower use of fossil fuels and increased production from renewable sources. This last one has allowed the decrease of the Group’s emission factor of 10% compared to 2019 (310 g/kWh), further improving the emissive trajectory in line with the SBTi target. Overall, in 2020, the use of waste-to-energy, production from renewable sources and cogeneration made it possible to avoid the production of 4 million tonnes of CO2 (+14% compared to 2019) and save 1,2 million TOE of primary energy.

Science Based Target Initiative (SBTi) approved A2A CO2 emission reduction targets

On March 2, 2020, SBTi declared A2A's direct and indirect CO2 emission reduction targets (Scope 1-2) aligned with the reductions required to keep global warming below 2°C (Paris Agreement – COP 21).

With the update of the new Strategic Plan, A2A has updated its CO2 reduction target for 2030, keeping it basically in line with the commitment communicated to the Science-Based Targets initiative. In fact, the Group expects to achieve an emission factor close to 226 gCO2/kWh, which gives it greater confidence in achieving the Science-based target (emission factor by 2030 equal to 230 gCO2/kWh).

The Group's commitment to combating climate change is demonstrated by the near-zeroing of Scope 2 emissions, four years ahead of schedule.

Still to date, the Group is the only multiutility at italian level recognized target alignment by SBTi.
