The direct emissions of CO2eq stood at around 1.35 million tonnes, a clear reduction compared with 2018 (-10%). CO2 emissions from combustion stood at around 0.656 million tonnes (-9.7% compared with 2018), while CO2eq emissions from methane and HFC emissions stood at around 0.69 million tonnes (-10.4% compared to 2018).

Natural gas emissions stood at 39.2 Mm3, a reduction compared with the figure of 44.4 Mm3 in 2018 (-11,7%).

The In-line gas recompression interventions, interventions with tapping machines, technology that makes it possible to disconnect pipelines in operation for new connections without an interruption to the service, and other initiatives have allowed Snam in 2019 to prevent the emission into the atmosphere of 9.4 million cubic metres of natural gas, equal to around 165,000 tonnes of CO2eq (+16% compared with the figure of 142,000 tonnes of CO2eq in 2018).

As a confirmation of the benefit of the measures taken, emissions of methane per kilometre of network for the transportation activities fell further (-12% compared to 2018 and -15.4% compared to 2017).

The Company’s performance indicators are in line with its methane emission reduction targets. Specifically, in 2019 Snam increased its reduction target for CH4 emissions by 2025, from -25% in 2018 to -40%. The current situation is in line with this target (-19%).

Furthermore, in 2019 Snam recovered the 56% of natural gas emissions during maintenance activities, in line with its target of 33% per year by 2022.
