6:By some accounts, the information and communications technology industry already is responsible for 2% to 3% of the world's greenhouse gas emissions, and data centers alone are on track to outpace the airline industry in the next decade when it comes to polluting the Earth.

193:While estimates indicate that the combined ICT industry is responsible for about 2% of the world's carbon emissions, telecom carriers are responsible for about .4%, said Susan Schramm, head of marketing for North America for Nokia Siemens Networks. "Of that .4%, radio base stations are the largest contributor to the problem," she said


16:Telcos in Canada, Europe and parts of Asia are ahead of their U.S. counterparts when it comes to implementing programs to reduce carbon dioxide emissions, mostly because of the Kyoto Protocol, a United Nations' agreement that requires participating countries to reduce their emissions of CO2 and five other greenhouse gases to a collective average of 5% below 1990 levels by 2012.


25:Bell Canada, BT, Nippon Telegraph & Telephone and other European telcos have calculated and published their carbon footprints and have set goals for reducing them. These companies have publicly reported their emissions in corporate social responsibility reports and through the Carbon Disclosure Project, an independent organization that requests carbon disclosures from the world's largest companies.


49:In the U.S., Qwest and Verizon have publicly disclosed their carbon footprints, but AT&T and Sprint have not. Both AT&T and Sprint said they recently have completed assessments of their carbon emissions and are now working on reduction goals.


60:As part of a commitment to going green, AT&T has invested about $14 million to take specific actions to improve efficiencies based on the results of comprehensive energy audits of the company's highest energy-consuming facilities, Lake said. "As a result, we realized 42 million kilowatt hours of energy savings just last year, so we are expanding the audits," she said.

ユーバースIP-STBでも省エネ 949:AT&T Inc. has joined the government's Energy Star program, which means that the company's Internet Protocol television set-top boxes have now been rated energy efficient. As an Energy Star program participant, AT&T U-verse TV will furnish customers with Motorola and Cisco Systems Inc. receivers that meet the new Energy Star energy efficiency criteria.


66:Sprint expects to publish its carbon footprint and goals before the end of the year, said Amy Hargroves, manager of corporate social responsibility for Sprint. The company is participating in the Environmental Protection Agency's Climate Leaders program, which, like the Carbon Disclosure Project, aims to help companies figure their carbon footprints and set goals for reducing them.

74:For example, 75% of the energy used at Sprint's 200-acre headquarters facility in Overland Park, Kan., is generated by wind. That makes Sprint the 15th-largest purchaser of renewable energy in the U.S. and puts the company on the EPA's Power Partners list.

BetterWorld Telecom

89:BetterWorld has created a paperless back office, and its internal systems are hosted in a wind-powered facility through hosting provider Sustainable Hosting. In addition, the company donates 3% of its revenue annually. "Our goal is to be donating $1 million a year by 2012," said Matthew Bauer, president and co-founder of BetterWorld.


102:Globally, BT gets credit for being one of the most aggressive in reducing its carbon footprint. The company's 2006 CO2 footprint measurement in the United Kingdom was .64 million metric tons of carbon emissions - a reduction of 60% from its 1996 total of 1.6 million metric tons. BT has pledged an 80% reduction of its 1996 total by 2016.

106:BT has employed a variety of strategies to reduce its carbon footprint, including cutting travel and increasing telecommuting, increasing energy efficiency in power and lighting systems and in networking equipment, and using renewable sources of energy to power its facilities. In the U.K., nearly all of BT's electricity now comes from renewable sources and combined heat and power plants.

340:And the operator is now on a mission to reduce its carbon emissions intensity by 80 percent globally by 2020. The operator has already cut emissions in the U.K. by 60 percent between 1996 and 2008. BT plans to meet the new target through improved energy efficiency, on-site renewable generation, and by buying low-carbon electricity. For example, BT aims to get 25 percent of its U.K. electricity from dedicated wind turbines by 2016. That would make a difference, considering that BT currently uses up 0.7 percent of the U.K.'s electricity supply.


112:Simply using conferencing and collaboration to replace travel and allow telecommuting saved BT nearly 100,000 metric tons of carbon in 2006, said Kevin Moss, head of corporate responsibility operations for BT. Today, almost 80% of BT's work force works at home at least part of the time.

177:"If [information and communications technology] represents 2% of global emissions, you've got another 98% coming from non-ICT sectors and from each of us as citizens of the globe," said Chris Kimm, vice president of sales and engineering for Verizon Business Premier Accounts. "We can help reduce that 98% by offering smart applications that facilitate energy efficiency." Kimm points to services such as collaboration, telepresence and electronic delivery of goods such as music and movies that would otherwise require packaging and shipping as examples of services telcos should be marketing as green. "ICT won't reverse climate change; it's no silver bullet," Kimm said. "But it is a piece of the solution."


125:"Communications companies spend about .8 to 1% of their revenue on energy," said Laddie Suk, global partner for innovation and transformation solutions for BusinessEdge Solutions, a consulting company. "That may not sound like a lot, but for a large operator, this can be hundreds of millions of dollars," he said. "Even a 10% cut in that is a significant savings."


131:Telcos are just beginning to use software systems to do real-time monitoring and management of energy consumption in their facilities. Using element management systems to reduce air-cycle times in cooling systems, manage generators and monitor battery usage, for example, can save telcos 15% to 35% on energy costs,


157:the U.S. California already has enacted a law mandating that the state's greenhouse gas emissions be reduced to 1990 levels by 2020


165:"The presidential candidates on both sides are proposing some kind of carbon cap, and many people feel it is inevitable that we will have carbon constraints in place soon in the United States," said Chris Lloyd, executive director of public policy and corporate responsibility for Verizon. "Quite frankly, the voluntary approach hasn't worked, and one would think that there will have to be a mandatory program to force companies to change their behavior. We view that as a tremendous business opportunity."


199:In an effort to help telcos reduce CO2 emissions, NSN introduced its compact Flexi Base Station, which China Mobile Group Beijing is using in the National Olympic Stadium. "We've also announced a road map to reduce the energy use of a typical GSM base station to 650 watts by 2010, which is a 20% reduction over 2000 levels," Schramm said. "We've pledged to reduce the energy use of CDMA base stations by 40%."


229:The Climate Savers Computing Initiative, a group started by Intel and Google, already has joined forces to develop Energy Star ratings for data center gear, and Ceuppens said he has approached these groups about extending the ratings to networking products.


239:Marc Benowitz, director and for Alcatel-Lucent, agrees that an apples-to-apples rating system for energy consumption is needed. The rating could be used to determine how many megabits per second, per watt a given piece of equipment is delivering - a kind of "miles per gallon" estimate for networking gear, he said.

アルカテルルーセントは規格化に積極的 244:Alcatel-Lucent is working with standards bodies such as the European Telecommunications Standards Institute and industry forums such as the Alliance for Telecommunications Industry Solutions to promote a common ground for energy metrics,


251:test solution vendor Ixia will demonstrate a proof-of-concept system called IXGreen, which is aimed at testing energy efficiency for equipment in data and switching centers. The test solution works by assigning a "green index" value to gear based on the amount of power consumed and heat dissipated when it is stressed under various traffic loads, said Vic Alston, senior vice president of product development for Ixia. Rather than develop its own test metrics, Ixia is using metrics from industry groups such as The Green Grid, which like CSCI is working on issues related to energy consumption in data centers


442:Verizon has set a target for new optical, switch, router, and other gear to be 20 percent more efficient by January 2009. Qwest Communications International Inc. (NYSE: Q - message board) and AT&T Inc. (NYSE: T - message board) reportedly support the concept of such standards.

ノーテル、シスコ戦争を起こしたTolly Report

302:The Tolly reports can be directly accessed by visiting the Internet: &link(レポート,


省エネとUCを武器にする 518:As a result, Nortel built its networking product line around a couple big priorities: energy efficiency and unified communications (UC). With cost, environmental, and (looming) political pressure building around energy efficiency, that's a no-brainer.

環境戦略への過程 561:Story behind the marketing campaignAt Interop's Energy Camp I also ran into April Dunford, who is Nortel's "Green" guru in the marketing department. She said that Nortel has created a Global Green Council that includes marketing, operations, and facilities. They have taken on green initiatives as a major marketing and promotional push for the company. They want to be seen publicly as a "Green company" by adopting internal policies and building energy-efficiency into their products.

568:Simultaneously, in recent years when Nortel decided to make a strategic push into LAN networking, the executives told the staff to go out and find something that they do better than Cisco. One of the sales engineers had a customer who remarked that Nortel's gear sucks a lot less power than Cisco equipment. The sales engineer took that information back to the company, which started testing this in its labs and quickly verified it to be true. Next, they commissioned Tolly Group to do a lab study and Tolly came up with similar results.

シスコは長期的に負けるか 612:"We're certainly seeing enterprises considering and buying other networking technology besides Cisco. The major beneficiaries are HP &verb(ProCurve?), Nortel and Foundry. However, overall Cisco's market share losses are fairly small - though we have seen a gradual erosion of the market share over a number of years. Based on number of ports sold into business Cisco's share has dropped from the low to mid 60% range in 2002/2003 to the low to mid 50% range in 2006/07. Cisco still clearly defines the market, but if you look at 2007 compared with 2006, Cisco's LAN revenues grew by 12%. HP &verb(ProCurve?) (+40%) , Huawei (+32%), Foundry (+26%) , Nortel (+18%), Alcatel-Lucent (+17%), Enterasys (+17%) and Force10 (+15%) all grew at (slightly) faster rates.

871:The Tolly report compared Nortel's 8800, 8300, 5520-48T-PWR, 4548GT-PWR switches and Nortel Secure Router 4134 with Cisco's Catalyst 6506-E, 4506-E, 3750-E PoE-48, 3560-E PoE-48 switches and Cisco 3845 Integrated Services Router. The report found that Nortel's equipment offers power savings ranging from 3.97% to 42.77% over their Cisco peers depending on the model.

シスコ社の反論 889:Cisco meanwhile responded on its own blog with data centre switching solutions manager, Omar Sultan, pointing out inconsistencies in Nortel's claims, mainly on the fact that the Tolly figures were arrived at when the equipment were simply plugged in and not carrying any traffic.



670:A new report by Insight Research claims that the telecommunications industry has the potential to abate as much as US$1.2 trillion worth in carbon emissions in the next five years by simply repackaging existing services into "green communications."

675:The report, "Communicating Green: Telecommunications Value in Promoting Environmental Improvement, 2008-2013," evaluated the use of existing telecommunications technologies and services applied to five key domains: transportation demand management to improve gasoline consumption; demand side management of electrical power, machine-to-machine communications to improve operational efficiencies; the recycling of electronic devices; and regulatory compliance and audits. To impact the environment positively in each of the domains, specific improvements were quantified in nine solution areas: mobile workforce; field services and personnel; data center operations; telecommuting; facilities/building management; environmental audit and compliance systems; branch and remote office capabilities; environmentally located data centers; and ICT equipment recycling.


989:""The Green Marketing Study"" from DoubleClick?, conducted by Opinion Research, contained a survey of online buyers, 60% of whom said it was ""extremely"" or ""very"" important that companies exercise sensitivity toward the environment.


714:The new group will focus in particular on the reduction of ICT emissions and how ICTs can assist in cutting emissions in other industry sectors such as energy, transportation and buildings.Group on ICTs and Climate Change, which is expected to complete its work by April 2009. The new group follows an earlier announcement by the ITU that it will systematically review all telecoms standards in light of climate change. A key objective of the Focus Group will be to develop internationally agreed methodologies to describe and estimate the impact of ICTs on climate change, both directly and through their application in other industry sectors. Work will start immediately using electronic means, and the group will meet physically for the first time at ITU headquarters in Geneva on 1-3 September 2008 under the chairmanship of David Faulkner of BT.
