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 always careful the environment

One of the commitments of the A2A Group has always been to combine the quality of services and economic development with environmental protection.

In 2019 the CO2 emissions are decreased by 7.2%, compared to 2018, due to a lower use of fossil fuels and, a to an increase of the production of energy from renewable sources. The latter allowed reducing the Group's emission factor (-9% compared to 2018), equal to 347 gCO2/kWh. In addition, NOx, SO2 and dust emissions from all waste-to-energy plants were well below the legal limits set for these pollutants.

In 2019 avoided CO2 emissions amounted to 3.5 million tonnes, 25% more than the value calculated for 2018, thanks to the production of the Group's plants

A2A's CO2 emission reduction objectives approved by science based targets initiative (sbti)

In 2019, A2A revised its CO2 reduction target to 2030 as part of its Sustainability Policy, supported also by the Group's new strategy which envisages significant development in the field of renewables, the optimization of gas-fired combined cycle plants and the reconversion of conventional coal-fired and fuel oil-fired plants.

The new target, approved by the Board of Directors of A2A on September 26, 2019, provides by 2030, for a 46% reduction in direct greenhouse gas emissions per kWh produced compared to 2017 (emission factor at 2030 equal to 230 gCO2/kWh).

Finally, the new target was submitted to the Science-Based Targets initiative (SBTi) - an initiative that stems from the collaboration between the Carbon Disclosure Project (CDP), the United Nations Global Compact (UNGC), the World Resources Institute (WRI) and the World Wide Fund for Nature (WWF) - to verify its alignment with the indications of the Paris Agreement (COP21).

The commitments also include a 100% reduction in Scope2 emissions by 2024, and a 20% reduction in Scope3 by 2030 (more specifically in the “Use of sold products” and “Purchased goods” categories).

The increase in new renewable installed capacity, which is the fundamental lever for containing the emission factor, is provided for in the Business Plan (500 MW by 2024 and 1.6 GW by 2030).

On March 2, 2020, SBTi declared A2A's direct and indirect CO2 emission reduction targets (Scope 1-2) aligned with the reductions required to limit the increase of global warming to 2°C. In addition, A2A's objective of reducing indirect emissions, linked to its value chain (Scope 3), is also in line with SBTI criteria and in line with international best practice.

To date, the Group is the only multiutility at Italian level recognized target alignment by SBTi.
