  • Aligned the A2A's emission targets with Paris Agreement: reduction by 47% of direct CO2 emissions (Scope1) at 2030; reduction by 100% of indirect CO2 emissions Scope2 by 2024; reduction by 20% of indirect CO2 emissions Scope3 by 2030
  • Improved all indicators relating to greenhouse gas emissions, linked to both direct and indirect emissions and the Group's value chain
  • Start of the project of an innovative system for the treatment of combustion fumes of the Brescia Waste-to-energy Plant, aimed at reducing emissions and recovering the residual heat still present in the fumes for the district heating system in Brescia
  • Use of coal at the Lamarmora plant abandoned
  • From January 2020, start of the supply of 100% renewable electricity certified by the "GO" (Guarantee of Origin) for all the A2A Group's sites

Electricity produced by type of source

(*)For non-hazardous waste, a renewable fraction of 51% was assumed (ref. Decree of the Ministry of Economic Development of December 18, 2008). Consequently, the non-renewable fraction was assumed to be 49%
