ENVIRONMENTAL AND SOCIETAL INFORMATION – HUMAN RESOURCES Reporting system and methodology

Changes in scopes The Group Polish companies were sold on 13 November 2017. The impact of this sale on non-financial figures is thus complete in 2018. Framatome joined the Group on 1 January 2018. Further details on the environmental 3.9.2.2 data The environmental data in this document are based on methodological sheets. This is the Group’s standard for reporting in force in 2018. All of the indicators relating to consumption and emissions are linked to the electricity and heat generation and marketing data, and to other processes related to these activities. If data are missing, particularly during the last days of the year, estimates are made on the basis of the best information available at that date. Dalkia’s environmental indicators in relation to energy are consolidated over a sliding year, from 1 December N-1 to 30 November N. Other indicators are reported over year N. Further details on the indicators relating to water withdrawn and water returned Indicators on cooling water include water withdrawn and water returned to rivers, the sea and water tables. For nuclear power electricity plants located on coastlines and for thermal power plants, the amounts of cooling water withdrawn and water returned are calculated on the basis of the operating time and nominal debit of pumps. The CCGT cooling circuit is open for MECO. All water is thus returned, and no significant consumption is to be reported. On this basis, no amounts have been reported by MECO from 2018 onwards. These indicators are not collected by EDF RE, a subsidiary of EDF Renewables in the United States, or by some Edison sites (only the operating centres managed by Fenice), as their values are negligible at Group level. Further details on air emissions Air emissions from thermal power plants of the EDF group are measured or calculated on the basis of analyses of the fuels or based on standard emissions factors. The Group’s SF 6 emissions are calculated, as a matter of priority, on the basis of a mass balance or, to a lesser extent, using an estimation method approved by Executive Management at the entity in question (for example, application of a leakage rate). GCC power plants outside EDF do not report dust emissions, which do not have a significant impact at the Group scale. MECO does not collect emissions of N 2 O and SF 6 , also without material impact at the scale of the Group. Dalkia Barkantine plant in the United Kingdom is outside of the scope. Indeed, emissions by that plant are negligible at Group level. The Global Warming Potential (GWP) coefficients were updated for 2018 according to the recommendations of ADEME and GIEC (1) . They are 30 for CH 4 , 23,500 for SF 6 and 265 for N 2 O. Scope 1 direct emissions The EDF group’s scope 1 emissions are made up of direct emissions (2) : 1. of CO 2 , N 2 O, CH 4 and SF 6 ; 2. from the vehicle fleet; 3. from buildings; 4. from refrigerant leaks; 5. from hydroelectric dam reservoirs. Historical reported data show a contribution of emissions from points 2, 3, 4 and 5 above of about 1.04% of the total of scope 1. Given the absence of these emissions at the reporting date, their amounts are estimated based on this historical contribution.

Scope 3 indirect emissions Every year, EDF establishes a greenhouse gas emissions report for the scope of the Group. It covers all of the companies in the non-financial reporting scope. Within this scope, the direct and indirect emissions (scopes 1, 2 and 3) are calculated according to the principles of the GHG Protocol Corporate Standard. The 2017 GHG report enabled us to identify significant information items adopted for the 2018 fiscal year. In 2017, the three items representing the highest contributions to GHG emissions were: direct emissions of CO 2 of 50.5 million tonnes (34% of total emissions), indirect emissions associated with the combustion of gas sold to our end-customers (30% of total emissions), and indirect emissions associated with electricity purchased to serve our end customers (10% of total emissions). Further details on conventional waste The conventional waste data were obtained on the basis of data available on the closing date for the quantities removed and the disposal channels. It should be noted that the reported data are not comprehensive concerning conventional industrial waste from EDF Renewables and from certain operational sites belonging to Edison (Fenice assets), as these data cannot, at this stage, be reported within the Group’s reporting deadlines. Dalkia reports on the most significant sites. Construction and decommissioning waste is included in this report, if its management falls under the responsibility of the EDF group. On the other hand, waste managed by service providers is not accounted for. Regarding Enedis, waste reporting is done on a rolling-year basis, from 1 November N-1 to 31 October N. Details on radioactive waste Concerning EDF Indicators pertaining to “Very Low Level radioactive Waste (VLLW) from operations and from decommissioning” take into account: the actual volume of the VLLW directly evacuated from the Industrial Gathering, ■ Storing, and Stockpiling Centre (Centre industriel de regroupement, d’entreposage et de stockage – CIRES) from the production sites, which corresponds: to the volume of waste produced in the year for operating sites, ■ to the volume of waste shipped in the year for sites being ■ decommissioned; the actual volume of VLLW waste packages sent to CIRES from Centraco (after ■ upgrading) connected to processing by incineration and by merging EDF metallic waste. The volume to be attributed to sites in operation and sites being decommissioned is determined in proportion to the tonnages delivered by the sites in operation and by the sites being decommissioned. Indicators pertaining to “Short Lived Low and Intermediate Level radioactive Waste (short lived LLW and ILW) from activity and from decommissioning” take the following into account: the actual volume of the short-lived LLW and ILW waste directly evacuated to ■ the Aube Storage Centre (CSA) from the production sites, which corresponds: to the volume of waste produced in the year for operating sites, ■ to the volume of waste shipped in the year for sites being ■ decommissioned; the actual volume of LLW and ILW waste packages sent to the CSA from ■ Centraco (after upgrading) connected to treatment by incineration and by merging with EDF waste. The volume to be attributed to sites in operation and sites being decommissioned is determined in proportion to the tonnages delivered by the sites in operation and by the sites being decommissioned. Since 2016, the reduction in the volume contributed by treatment before storage (by ANDRA) has also applied to VLLW and also to packages sent by Centraco, where applicable. It includes the reduction in volume resulting from treatment before storage (the case of super-compacted waste). For the indicator “Long-Lived High- and Intermediate-Level solid radioactive Waste”, the packaging of the waste is taken into account in the calculation. Given the technical constraints linked to processing operations, the packages are produced approximately ten years after the fuel has effectively generated waste. The indicator is thus an estimate that relies on the long existence of current
