Indirect CO_2eq Emissions (Scope 2)

The Indirect CO_2eq energy emissions are due to the procurement of electricity and heat produced by third parties and used by Snam for its activities. Snam calculates indirect CO_2eq emissions through the Market Based (MB) approach, which gives a nil CO_2eq emission factor for energy consumption from renewable sources, and the Location Based (LB) approach, which instead considers an average CO_2eq emission factor of the national electricity grid.

In 2018, total electricity consumption increased by +12% compared with 2017, as a result of two new compression stations (Minerbio and Sergnano) coming into service and greater use of storage plants as a result of the greater amount of gas stored (+9%) and increased ICT consumption (+18%) due to the installation of new equipment.

Emissions (calculated using the MB method) stood at 31,887 tonnes of CO_2eq (+10.9% compared with 2017), a lower rise compared with energy fees. In 2018, Snam increased the consumption of electricity produced from renewable sources, which went from 35.4% in 2017 to 37% in 2018, thus avoiding emissions into the atmosphere of approx. 12,100 tonnes of CO_2eq (11,040 tonnes of CO_2eq with respect to those of 2017). The emissions avoided correspond to approximately 39% of total indirect Scope 2 emissions.
