Overview
The EU Code of Conduct for Energy Efficiency in Data Centres (EU Data Centre CoC) was launched by the European Commission’s Joint Research Centre (JRC) in 2008 in response to the rapid growth in electricity consumption from data centres across Europe. The initiative aims to encourage data centre operators and owners to reduce energy demand in a cost-effective manner without compromising operational reliability or mission-critical performance.
The Code of Conduct is voluntary rather than legally binding. Organisations can participate either as “Participants” — operators managing data centre facilities — or as “Endorsers,” such as equipment vendors, consultants, or industry associations supporting the initiative and promoting its principles.
The framework focuses on improving awareness of energy use within data centres and promoting recognised efficiency best practices. These practices span areas including cooling systems, power distribution, IT equipment management, airflow optimisation, monitoring, and organisational governance. The initiative also supports broader EU sustainability objectives by helping reduce greenhouse gas emissions and improving infrastructure efficiency.
Key provisions
The EU Data Centre Code of Conduct is centered on a set of operational and management practices intended to improve energy efficiency across data centre facilities. Key provisions include:
Energy monitoring and reporting: Participants are expected to measure and report data centre energy consumption and efficiency metrics to support benchmarking and performance improvement.
Implementation of efficiency best practices: The framework provides guidance on reducing energy use across cooling systems, airflow management, IT equipment, and electrical infrastructure.
Minimum recommended efficiency measures: Participants are encouraged to adopt a baseline set of recognised operational and technical efficiency practices where feasible.
Continuous energy performance improvement: Organisations are expected to regularly assess operations and pursue ongoing reductions in energy consumption and associated emissions.
Management and governance processes: The guidelines encourage organisations to integrate energy efficiency into operational planning, procurement, maintenance, and organisational governance.
Current Status
The EU Code of Conduct for Energy Efficiency in Data Centres remains an active voluntary initiative administered by the European Commission’s Joint Research Centre. The framework continues to be updated annually through revised Best Practice Guidelines, with the latest editions published in 2024 and 2025. Although voluntary, the initiative has become increasingly influential within the EU regulatory landscape. The Code’s best practice framework is referenced in EU sustainable finance and energy efficiency legislation, including the EU Taxonomy Delegated Act and the recast Energy Efficiency Directive. The initiative also continues to attract participation from data centre operators, cloud providers, vendors, and consultants seeking to demonstrate alignment with recognised energy efficiency standards.
