A number of sustainability rankings in the US and Europe let us take a look at how telecom providers perform compared to each other and to broader tech sectors. Sprint-Nextel is best in the United States. Sprint's take-back program was ranked tops in the US in 2012 and was the only carrier in the top quartile of Greenpeace's 2013 Cool IT Leaderboard. France Telecom, KPN and Vodafone have received consistently good marks with global rankings.
Most Green ICT attention focuses on the data center. There is growing evidence that data centers represent a minority of total ICT energy consumption and carbon emissions.
Here we track gear for consumers and small businesses seeking ICT resiliency. This is a wide range of ICT-related gear suitable for areas or situations lacking reliable grid power. Our latest is a portable stove uses twigs for fuel to cook and to charge a smartphone.
A MarketsandMarkets report says, "The global volume of e-waste generated is expected to reach 93.5 million tons in 2016 from 41.5 million tons in 2011 at a CAGR of 17.6% from 2011 to 2016." Three strategies for dealing with an organization's aging ICT gear are scrap, external reuse, and internal reuse. Internal reuse offers a growing number of increasingly sophisticated options while external reuse is revealing some unintended consequences.
The Greenpeace Cool IT Leaderboard assesses the external impacts and internal efforts of 21 global IT companies to mitigate climate change. While the list has grown, several major companies like Apple and Facebook are absent. The Leaderboard originally took the unique approach of identifying by name each company's chief executive in its listings, but backed off in April 2010. Several years of improvements vanished in 2012, largely due to weak scores for political advocacy. Scores continue to be low in 2013, although most companies did improve.
Most ICT gear - core facilities, communications infrastructures, and edge devices - runs on DC power. Converting AC to DC within a building is inefficient, on-site renewable power generation is usually DC to begin with, and super-efficient LED lighting is also DC. So DC power distribution has been a attractive option, but there have been vigorous arguments for and against. Recent events suggest the tide is turning in favor of DC distribution, although skeptics continue to press their case. The growing use of solar-generated electricity might be providing the latest boost DC.

"Were America's Millions of Analog TVs Recycled?" That's the question we began asking five years ago as the United States converted from analog to digital television (DTV), obsoleting the traditional CRT-based sets. The answer now appears to be "no" due to consumer behavior and a declining market for CRT by-products.
GreenTouch published in May 2013 its Green Meter research study. "The analysis indicates that net energy consumption in networks can be reduced significantly—up to 90 percent—by 2020. The study takes into account new technologies, architectures and protocols, as well as the dramatic increases anticipated in communications traffic over the next decade."
I've noted that research labs are examples of ICT faculties that consume considerable energy. I've also noted communications gear giant Cisco's work on Green ICT. These two topics have come together as Cisco turns its attention to energy use in its own labs.
The NCAR-Wyoming Supercomputing Center (NWSC) in Wyoming "provides advanced computing services to scientists studying a broad range of disciplines, including weather, climate, oceanography, air pollution, space weather, computational science, energy production, and carbon sequestration. It also houses a landmark data storage and archival facility that will hold, among other scientific data, unique historical climate records." It has also become of the focus our largest Twitter discussion of the 2013.
