ENGIE, a player committed to reducing methane emissions

Fugitive natural gas emissions (mainly methane) from the gas infrastructures controlled and operated by ENGIE are one of the sources of the Group's greenhouse gas (GHG) emissions. 
They are the primary source of direct GHG emissions for the Group's activities as operator of distribution networks, storage facilities or LNG terminals, and the second largest source for its activities as operator of transmission networks, just after the emissions linked to the consumption of gas as the driving force of the transmission network. 

Methane releases generally occur during operations or maintenance (e.g. venting of a pressure-reducing station), venting the gas is a safety procedure for gas infrastructures operation and then vented emissions may be the results of testing this procedure or real implementation of this procedure in case of danger¹. More rarely during commissioning or shutdown operations (e.g. purging of a pipeline), and very exceptionally during operating incidents (e.g. following damage to a pipeline caused by the work of a third-party operator). The other minor sources of GHG emissions from gas infrastructure operators are direct emissions from the entities' vehicle fleets (Scope 1), indirect emissions linked to energy consumption in buildings (Scope 2) and those linked to purchases of goods and services (Scope 3). 

ENGIE's commitments

ENGIE has been committed for several years to reducing its emissions and today, thanks to these efforts, the group's CH₄ emissions are 1.57 Mt CO_{2 eq} in 2021, which represents less than 1% of the Group's total balance of 166 Mt CO_{2 eq}. 

This voluntary commitment has been translated into commitments at the entity level. In 2020, the Group's gas infrastructure managers GRDF, GRTGAZ (including ELENGY) and STORENGY (Storengy France, Storengy UK, Storengy Deutschland) joined the Oil & Gas Methane partnership 2.0 initiative managed by the United Nations Environment Program, which aims to minimize fugitive methane emissions and to share an internationally recognized reporting framework in this area and focus on reduction approach. These commitments are detailed below:

The commitments of these entities are monitored by the United Nations Environment Program (UNEP), which has created an International Methane Emissions Observatory called “An Eye on Methane”.
The observatory has ranked GRDF (Cf.report page 109), GRTGAZ (Cf. report pages 78-79), GRTgaz Deutschland, ELENGY, STORENGY France, UK and Germany  (Cf report pages 93-95) at the highest level of commitment in 2021, namely gold standard. Full details are available in the report:

Figures in details

The following table shows the direct GHG emissions (scope 1) of each of the Group's infrastructure activities worldwide.

In addition to methane emissions, other sources of direct emissions are: emissions from the entities' vehicle fleets, emissions from stationary combustion and CO₂ emissions from gas flaring.

The table below shows the CH₄ emissions of each of the Group's infrastructure activities worldwide.

The table below shows the absolute CH₄ emissions per unit of activity for each type of infrastructure illustrate the unit performance of each activity in this area expressed in g CO₂ per kWh :

Or in % of energy delivered, with a conversion factor of 15.13 kWh/kg for methane:

Concrete actions implemented to reduce our emissions

Here are some concrete actions that are being implemented this year, as part of these commitments to reduce methane emissions: 
 

_{¹ during maintenance operations, a fortuitous shutdown of a site or security tests are required by the French administration. So,  French UGS operators must carry out venting security operations with strictly compliance with gas storage underground gas storage regulation.}
