Directive européenne CSRD sur le reporting extra-financier
Les “activités durables” de l’entreprise sont définies par la taxonomie européenne.
Le premier exercice (pour les entreprises concernées) est à effectuer en 2025 sur les activités de 2024.
Une activité IT “Data hosting” est considérée comme alignée avec la taxonomie si elle est hébergée dans un datacenter qui :
Les hyperscalers devraient publier un pourcentage d’alignement de leurs DC en 2024.

Focus on the new requirements for DC introduced by the�Energy Efficiency Directive (EED)

Recast Energy Efficiency Directive (EED)
Obligations for high energy intensive enterprises (Article 11)
See directive 2023 here
The Directive 2012/27/EU establishes measures to help the EU reach its energy efficiency. It covers mandatory energy audit for large companies from tertiary, industry & transport sectors, smart meters roll out for electricity & gas, energy efficiency obligation scheme, requirements for District Heating & Cooling (DHC) infrastructures, protection of the rights of consumers to receive easy and free access to data on real-time and historical energy consumption information displaying.
The version adopted on September 2023 introduces

Article 32 obliges MS to lay down rules on penalties applicable to infringements.
These penalties shall be “effective, proportionate and dissuasive”. Each MS must notify the Commission of those rules by October 11, 2025
See directive 2023 here
Recast Energy Efficiency Directive (EED)
New obligations specific to data centers owners & operators (Article 12)
Objective: this first delegated regulation sets out the information and key performance indicators (KPI) needed from data centres as well as the first sustainability indicators that can be used for the assessment of the sustainability of data centres.
Scope: This delegated regulation includes six articles that cover subject matter and scope, definitions of terms, introduce the reporting mechanism for the sustainability of data centres, introduce the data centre sustainability indicators, and set out the specifications of the European database.
Content:
The regulation’s four Annexes define:

EED: 1st delegated act adopted on March 2024
Once the Commission has adopted the act, Parliament and Council generally have two months to formulate any objections so theoretically ... ‘some surprises’ may occur within May 13.

1 Energy & sustainability indicators | j | Waste heat reused (“EREUSE” in kWh) following CEN/CENELEC EN 50600-4-6 std or eq. NB1: defining the boundaries of DC is key since only energy reused outside the boundaries of the DC is counted. NB2: if part of the waste heat is reused for cooling the DC that part must be subtracted from the reused waste heat |
k | Average waste heat temperature (“TWH” in C°) shall be measured as the temperature of the fluid used to cool the ICT equipment in the DC computer room averaged over the year, and across every measurement points. | |
l | Average setpoint information technology equipment intake air temperature (“TIN” in C°) measured as the average setpoint temperature in all DC rooms, set as a setpoint command to the cooling system used for the ICT equipment averaged over the year | |
m | Types of refrigerants used in the cooling and air conditioning equipment | |
n | Cooling degree days (“CDD” in degree-days) for the location of the reporting DC during the last calendar year, by using the methodology used by Eurostat and the JRC or equ. and with a base temperature of 21 C° NB: open access sources shall be used to determine the CDD | |

q | Total renewable energy consumption from Power Purchasing Agreements (“ERES- PPA” in kWh) NB: any GO created as a result of such PPA must be included in ERES-PPA. Otherwise, the concerned amount of energy shall be subtracted from the measured ERES-PPA. | |
r | Total renewable energy consumption from on-site renewables (“ERES-OS”, in kW) NB: any GO created as a result of on-site Ren sources must be owned and retired by the reporting DC. Otherwise, the amount of energy in question shall be subtracted from the measured ERES-OS. | |

ICT capacity indicators to be communicated
Annex II of the delegated act
N° | Description | |
2 ICT capacity indicators | a | ICT capacity for servers (“CSERV”) = the sum of the SERT active state performance or eq for all servers as declared in the manufacturer information in accordance with Regulation 2019/424 The active state performance value for the configured server or group of servers in a DC computer room shall be either interpolated from the declared active state performance value for a configuration declared under the Regulation (EU) 2019/424, or provided by a server manufacturer, or provided by a table of values for CPU part numbers created from a large SERT dataset, or estimated from a large dataset of measured values where a “recognized” calculation method exists. |
b | ICT capacity for storage equipment (“CSTOR” in petabytes) shall be the storage capacity, namely the sum of the raw (addressable) capacity of all SSD and HDD storage devices installed in all the storage equipment as declared by the storage device manufacturer. NB: colocation data centre operators may calculate CSTOR by extrapolating the value that corresponds to at least 90% of the installed information technology power demand of all new storage equipment installed in the reporting data centre. | |
See annex II to the delegated act adopted on March 14 2023 here
ICT capacity is measured for servers and data storage products as servers and data storage products are defined in the Commission Regulation (EU) 2019/4244 that laydown ecodesign requirements for servers and data storage products
NB: it does not refer to the Regulation 2021/341 that amends part of the 2019 Directive
25
Focus on SERT metrics related to energy efficiency
For each of load levels, energy efficiency is calculated as follows :
See SERT’s Run and Reporting Rules @https://www.spec.org/sert2/SERT-JVM_Options-2.0.html
NB: contrary to the arithmetic mean, the geometric mean treats relative changes in efficiency equally at each load level.
NB: SERT worklets are not designed to explicitly exercise General Purpose Graphics Processing Units (GPGPUs)
26
Data traffic indicators to be communicated
Annex II of the delegated act
See annex II to the delegated act adopted on March 14 2023 here
Data centre operators may base the monitoring and measurement of these indicators on any adequately reliable sources or combination of sources of data available, including data measured directly by the operator, data reported by data centre customers, or data provided by telecommunication operators and service providers !
N° | Description | |
3 Data traffic indicators | a | Incoming traffic bandwidth (“BIN” in gigabytes per second) shall be measured as the total provisioned bandwidth for incoming traffic to the data centre compute. |
b | Outgoing traffic bandwidth (“BOUT” in Gbs) shall be measured as the total provisioned bandwidth for outgoing traffic from the data centre computer room, aggregated for all the connectivity capacity, and averaged over the year | |
c | Incoming data traffic (“TIN”, in exabytes) shall be measured as the total incoming data to the data centre computer room, aggregated over the course of the reporting year, irrespective of the number of the data centre’s connections. | |
d | Outgoing data traffic (“TOUT”, in exabytes) shall be measured as the total outgoing data from the data centre computer room, aggregated over the course of the reporting year, irrespective of the number of the data centre’s connections. | |
Publicly available information in the EU database �Focus on Annex IV of the delegated act
27
Article 12 of Directive 2023/1791 states that information subject to Union and national law protecting trade and business secrets and confidentiality must not be made publicly available and requires that the European database be publicly available on an aggregated level. KPI communicated pursuant to Article 3 shall also be considered as confidential information
=> Annex IV of the delegated act introduces 5 size categories for the aggregation.
Publicly available information in the EU database �Focus on Annex IV of the delegated act
28
Timeline & specific guidances
The information and KPI shall cover the calendar year immediately preceding the reporting year
NB: This communication shall take place via a national reporting scheme if the Member State where the reporting data centre is located has established such a scheme. Otherwise, the DC operators shall communicate this information and KPI directly to the European database.
