Émissions de gaz à effet de serre [ENGLISH]

This graph shows annual and monthly trends in CO2 emissions linked to electricity generation.

The data can be of various kinds:

• Data from RTE meters and distribution network operators. In order to draw up global consumption or production balances, we need to have an aggregated view of all metering data on the transmission and distribution perimeters. These data are only available on the 15th of each month for the month just ended. Although updates are possible for at least 12 months, the consolidated data is very robust from the first date of availability.
• Provisional data, derived from telemetry set up by network operators at various points on the power grid, supplemented by estimates for non-telemetered production or consumption. Provisional data provide an initial overview, available very quickly after each deadline; they are not of the same quality as metering data (estimates taken into account, less accurate measurement than metering data, etc.). Graph elements based on provisional data are indicated by a specific pictogram on the portal.

Greenhouse gas emissions are calculated from generation values by energy source and normative emission coefficients established by ADEME. 

The graph shows the greenhouse gas emissions associated with electricity consumption in France. 

- Electricity consumption in France may be supplied by generation located in France. In this case, greenhouse gas emissions are deducted from the emission coefficients for each of the sectors concerned. 

- Electricity consumption in France may be supplied by energy imported from abroad, in which case emissions are calculated using the average emission rates of the countries from which the energy is imported. 

Two calculations are presented: 

- direct emissions, taking into account emission rates that reflect only emissions linked to the operation of production units,

- life-cycle emissions, which take into account all emissions linked to all stages in the life cycle of production units.
