Climate change

alt

In 2016, total direct and indirect greenhouse gas emissions (GHG) scope 1-2-3, amounted to approximately 1.8 million tonnes

alt

The total energy produced by renewable source plants increased by 14% compared with 2015

Natural gas covers 96.2% of Snam’s energy requirements

The international scientific community considers the greenhouse gas emissions responsible for climate change to be in progress. The greenhouse gases emitted by Snam’s operations are:

  • carbon dioxide, produced in combustion processes and directly related to fuel consumption;
  • methane, the main component of natural gas. Natural gas emissions are derived partly from normal plant operations and partly from discharges into the atmosphere caused by maintenance works or leaks.


Snam’s commitment to preventing climate change consists mainly of:

  • developing plant infrastructure to increase natural gas use throughout Italy, offering millions of residents, businesses and production plants the opportunity to use an energy source with a low environmental impact;
  • the use of natural gas as a primary energy source. The use of natural gas instead of oil products or coal is one of the most beneficial and feasible ways of reducing carbon dioxide emissions (CO2) and can make a significant contribution to achieving the objective of reducing greenhouse gas emissions;
  • reducing natural gas emissions from its own plants through continuous monitoring and specialised gas recovery interventions. In 2016, several interventions were carried out resulting in the recovery of 4.5 million cubic metres of natural gas (representing approximately 77,780 tonnes of CO2eq avoided)  and various technologies were implemented to reduce natural gas emissions from the pneumatic equipment;
  • use of electricity from renewable sources, Snam increased the number of plants supplying it with electricity generated from renewable sources, including: the Messina and Terranuova Bracciolini compression stations (Snam Rete Gas); the gas storage concession in Brugherio (Stogit); and the regasification plant in Panigaglia (GNL Italia). Therefore, due also to the use of photovoltaic panels for power generation, the avoidance of approximately 7,630 tonnes of CO2eq ,representing about 27% of Snam Group total indirect emissions (scope 2), was enabled;
  • promotion of energy efficiency  through the installation of photovoltaic panels in building construction;

Besides, Snam participates to Climate Disclosure Project (CDP) questionnaire, CDP beeing one of the world’s most important non-for-profit organization, which assesses companies’ transparency in the disclosure of information on climate change and greenhouse gas emissions, as well as in the management of water resources. From October, we were included in the exclusive A list of the CDP.

Total direct ghg emissions - scope1 (ktCO2eq)

 
  • Direct CO2 emissions from combustion : approximately 0.6 million tonnes;
  • CO2eq emissions from methane emissions: approximately 0.84 million tonnes..

The CO2eq emissions were calculated based on a global warming potential (GWP) of 28 for methane, as indicated in the scientific study of the Intergovernmental Panel on Climate Change (IPCC), “IPCC Fifth Assessment Report”.

indirect ghg emissions - scope 2 (ktCO2eq)

 

 

In 2016, indirect emissions (Scope 2) were recalculated and compared, for previous years as well, according to the most recent best practices, adopting two approaches called Market Base (MB) and Location Base (LB).
In 2016 indirect emissions of CO2eq calculated using the MB approach were equal to 27,390 tonnes (+3.6% compared with 2015), while the same emissions
measured using the LB approach stood at 28,280 tonnes, a 5.1% increase compared with the previous year.

Snam plants - Emissions Trading (at 31.12.2016)

Before the Emissions Trading regulations on climate change came into effect, Snam had already undertaken initiatives to contain emissions using high-yield technologies and natural gas as the main fossil fuel in its plants. Natural gas is used almost exclusively as fuel in the emissions trading plants.
