PARIS, September 28, 2010 /PRNewswire/ -- Digital Realty Trust, Inc. , the world's largest wholesale data centre provider, has adopted EDF's Certificats Equilibre scheme at its Paris data centre. The facility in the French capital has now funded 8,921,000 kWh of renewable energy within the national electricity network. Introduced in coordination with clients at the data centre, the scheme enables Digital Realty Trust to participate in the development of responsible energy sources within one of its key European markets.

As a company we have a firm belief in the value of green initiatives. Working with both our customers and EDF, we are pleased to contribute to the use of renewable energy within the French market, commented Bernard Geoghegan, Senior Vice President of International Operations for Digital Realty Trust. Throughout our portfolio we have achieved top accreditations in the LEED and BREEAM green building certification schemes, and have an ongoing participation in the Green Grid. Through that contribution we have helped raise the standards for green data centres in the wider market, and are currently working on new technologies to further reduce the environmental impact of data centres.

Our space in Digital Realty Trust's data centre gives us a strong presence in this important French market and has allowed us to directly support the development of controlled and responsible energy sources, says Mathieu Louvrier, Director of Business Continuity and Recovery Services at IBM France. The Certificats Équilibre scheme enables us to contribute to France's national objectives for the use of renewable energy, and to reinforce our own commitment to greener data centres.

For each certificate purchased within EDF's Certificats Equilibre scheme, EDF guarantees to place 1 MWh (1000 kWh) of electricity, which has been produced using renewable energy sources, into the French electricity network. Equilibre certificates are certified by the independent body Observ'ER.
