What do we mean by Green?

Why now? (broad factors) Economic crisis New government funding Obama plan promotes green technology Greener broadband access can win more government funding, rebates and tax incentives Social responsibility Be the leading corporate citizen in your market Competitive advantage “ Outgreen” your competition Outgreening becomes a survival strategy Green Telecom @ CTIA Conference - March 31, 2009

Economic crisis

New government funding

Obama plan promotes green technology

“ Outgreen” your competition

Outgreening becomes a survival strategy

Why now? (industry drivers)* Green Telecom @ CTIA Conference - March 31, 2009 Studies show the Information and Communications Technologies (ICT) sector can play a key role in greenhouse gas reduction: ICT-enabled solutions could cut annual CO 2 emissions in the U.S. by up to 22 percent in 2020. A 7% increase in broadband adoption could result in $6.4 billion per year in mileage savings from unnecessary driving and 3.2 billion fewer pounds of carbon emissions in the U.S. Substituting video conferencing for 10% of business air travel would reduce carbon emissions in the U.S. by some 35 million tons annually. Widespread use of broadband has the potential to reduce carbon emissions by more than 1 billion metric tons. *All claims and numbers on this page from March 2009 ATIS Report On Environmental Sustainability.

Studies show the Information and Communications Technologies (ICT) sector can play a key role in greenhouse gas reduction:

ICT-enabled solutions could cut annual CO 2 emissions in the U.S. by up to 22 percent in 2020.

A 7% increase in broadband adoption could result in $6.4 billion per year in mileage savings from unnecessary driving and 3.2 billion fewer pounds of carbon emissions in the U.S.

Substituting video conferencing for 10% of business air travel would reduce carbon emissions in the U.S. by some 35 million tons annually.

Widespread use of broadband has the potential to reduce carbon emissions by more than 1 billion metric tons.

Why now? (network drivers)* Largest single OPEX in network = power Accounts for more than 50% of mobile operator's OPEX Area of greatest need and OPEX reduction potential Base station (PA) the dominant power consumer (>70% of site power) 4G will require greater energy efficiency Larger data volumes at higher speeds More efficient data transmission technologies will require more power 4G = opportunity to implement green technologies Emerging economies India, Africa, other countries building new infrastructure They are struggling with availability and reliability of power grids Green Telecom @ CTIA Conference - March 31, 2009 *All claims and numbers on this page from January 2009 Unstrung Insider report.
