Climate change

In 2017, total direct and indirect greenhouse gas emissions (GHG) scope 1-2-3, amounted to approximately 1.75 million tonnes

The total energy produced by renewable source plants increased by 24% compared with 2016

Natural gas covers 96.6% 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 2017, several interventions were carried out resulting in the recovery of 4.1 million cubic metres of natural gas (representing approximately 71,500 tonnes of CO2eq avoided)  and various technologies were implemented to reduce natural gas emissions from the pneumatic equipment;
  • use of electricity from renewable sources, in 2017, Snam increased the consumption of electricity produced from renewable sources, which passed from 28% in 2016 to 35% in 2017, thus avoiding emissions into the atmosphere of approx. 11,040 tonnes of CO2eq (7,860 tonnes of CO2eq with respect to those of 2016). The emissions avoided correspond to approximately 35% of total indirect Scope 2 emissions;
  • 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. In 2017, we were confirmed in the exclusive A list of the CDP.

Total direct ghg emissions - scope1 (ktCO2eq)

 
  • Direct CO2 emissions from combustion : approximately 0.69 million tonnes;
  • CO2eq emissions from methane emissions: approximately 0.80 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)

 

 


Snam calculates indirect CO2eq emissions in accordance with best practices that calls for the calculation through two different approaches: the Market Based (MB) approach, which gives a null CO2eq emission factor for the energy consumption from renewable sources, and the Location Based (LB) approach, which instead considers an average CO2eq emission factor of the national electricity grid.With the MB approach, emissions amounted to 28,758 tonnes (+2.0% compared to 2016), while the same emissions evaluated with the LB approach amount to 31,738 tonnes (+9.2% compared to 2016).
In particular, the MB approach highlights the contribution to the reduction of emissions from the use of energy produced from renewable sources.

Snam plants - Emissions Trading (at 31.12.2017)

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.
