LONDON, June 30 /PRNewswire/ --

- Organization Commits to Cutting Carbon Footprint by Half

Global Crossing (Nasdaq: GLBC), a leading global IP solutions provider, today announced that it is providing Natural England with end-to-end telephony services across 44 sites and 2,500 users in the UK in a drive to help the organization meet its aggressive targets to shrink its carbon footprint and to bring all of its disparate telephony systems together. Global Crossing will install an IP VPN, which will deliver Hosted IP Telephony and managed videoconferencing among other services, including all associated equipment. This will facilitate the migration of all of Natural England's existing equipment onto one platform and promote the use of collaboration services in Natural England's business.

Natural England was formed in October 2006. The organization exists to conserve and enhance the natural environment for its intrinsic value, the well-being and enjoyment of people and the economic prosperity that it brings.

The consolidation enabled by Global Crossing will merge three telephony estates, creating an opportunity for Natural England to take a lead among government agencies on environmental issues. The solution from Global Crossing will demonstrate how next-generation communications services can deliver cost savings and, most importantly, cut carbon footprints.

"On examining how to merge our telephony estates, we conducted in-depth analysis on the best approach, best supplier and benefits we could deliver back to the organization," said Barney Smith, head of knowledge management and Information Services, Natural England. "We estimate that the cost of this installation will be approximately 1 million pounds Sterling, with a potential return of 3.2 million pounds over the next five years. Most of this will come from reduced travel expenditures, while videoconferencing will yield savings of 20,000 man-days and two million miles of car journeys."

Anthony Christie, Global Crossing's managing director for EMEA, said: "We're committed to helping Natural England achieve its mission to cut its carbon footprint by at least 50 percent by 2010. With travel accounting for 68 percent of Natural England's carbon footprint, Global Crossing's collaboration services offer an extremely reliable, robust and cost efficient alternative for communicating face to face, while keeping traffic off the roads and enabling employees to make far better use of their time."

"Our aim is to lead the way and to begin demonstrating cost savings within six months. We feel entirely confident that with Global Crossing and its approach to providing us with end-to-end managed services, we're already well on the road to achieving our goals," concluded Smith.
