Content Delivery Network (CDN) services provider Akamai has launched a major initiative to reduce its GHG emissions. Most notable is its commitment to an absolute, not relative, reduction.
Akamai's May 2016 announcement: "Today we are committing, by 2020, to reduce our absolute greenhouse gas emissions below 2015 levels by sourcing renewable energy for 50 percent of our network operations."
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 often DC to begin with, and super-efficient LED lighting is also DC. All this seems to make DC power distribution an attractive option for ICT facilities, but there have been vigorous arguments for and against. Recent events, beginning a 380-V DC standard for ICT power distribution in 2011, suggest the tide is turning in favor of DC distribution.

I had just finished updating my field report on personal solar for devices with my Grand Canyon experiences when I colleague sent me similar information about the Middle East. The Huffington Post reports that, "In Sanliurfa, Turkey, shepherds haul out personal solar panels to charge their phones...Fifty-nine percent of adults own smartphones in Turkey..." These personal solar panels look a little heftier than the one I was using, but they have to be donkey-compatible. Check out all the pictures on the Huffington Post article, courtesy of Getty Images.
I don't go into the backcountry device-free. A smartphone, with backcountry GPS software, and a digital camera are always with me. Planning for an 11-day rafting/hiking trip through the Grand Canyon in April raised the issue of how to power my gear. I decided to go solar to minimize battery consumption. A February week in the Mojave desert (right) gave me a chance to sort out candidate devices and to configure a compact but workable system. Here are reports from the Mojave and Grand Canyon trips.

The data center community has been very focused on reducing energy cost with "free cooling" - disposing of waste heat using natural cooling sources such as cold air and cold water. Even use of seasonal ice for datacenter cooling has been considered! Now, an article from Brazil offers a a unique perspective on a bias implicit in this focus.
A colleague in the financial services sector asked me about the integration of Green ICT into a taxonomy for sustainability certification.
My experience with taxonomies, particularly as founder of a business information company, has given me a crucial insight. Thoughtful construction up-front is the most beneficial, and the most neglected, aspect of taxonomy applications With that in mind, here are two key considerations for a successful Green ICT taxonomy implementation.
Apple recently issued a "Green Bond". What is this new kind of debt instrument and how might it propel Green ICT?
Most Green ICT efforts focus on hardware. That make sense, because hardware lifecycles encompass everything from environmentally responsible sourcing of its raw materials through energy efficiency of its use to sustainable disposal at its end-of-life. Special utility software such as desktop power-saving plays a central role in Green ICT, but less attention has been given to the application and system software in the gear, itself.
Vertatique has covered much innovation in Green ICT technology and practices. Now, we get to look at green ICT financing as Apple issues a Green Bond.
Apple announced the $1.5 billion debt instrument in a February 2016 filing with the Securities and Exchange Commission (SEC), the the American regulatory agency for such matters. Apple's SEC filing contains interesting about the concept of a Green bond and the company's planned use of proceeds. We will exerpt it here, because this information is buried in a very lengthy technical document.
GSICT is the first IEEE International Workshop on Green Standardizations and Industry Issues for ICT and Relevant Technologies, held in conjunction with IEEE Global Communications Conference (GLOBECOM). GSICT was organized by Dr. Jinsong Wu of the University of Chile.
