The "C" in Green ICT is Communications. Green America reports that, "The four largest companies – AT&T, Verizon, Sprint and T-Mobile – collectively use more than 30 million MWh of electric power each year. AT&T and Verizon, the two leading US companies in the industry, have a combined electricity usage that could power 2.6 million homes for a year...A large portion of this energy (90%) powers wireless access networks, towers and other infrastructure allowing cell phone users to access data and connect nationwide." Here's how telecoms are doing from a Green ICT perspective.

Following release of the 2017 Green Power Leadership Awards, EPA released its 2018 Green Power Partner rankings.

ICT companies show less dominence of the top slots than they did five years ago. This is true in both US and Global rankings.

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.

ICT companies appear to be boosting their use of renewable energy. Indicators include the Vestas 2012 Corporate Renewable Energy Index (CREX) and Apple's recent announcement about progress toward its 100% renewable goal.

We've often noted how different sustainability rating yield different results. That's why we make the effort to contrast them in visual formats like the table below, comparing recent Computerworld and Newsweek rankings. The two agree on Fujitsu and HP, but don't always converge after that.

CME Group Index Services publishes the Dow Jones Sustainability Indexes. Which ICT companies perform best on the 2011 Indexes?

A coalition of Chinese NGOs allied with the Institute of Public and Environmental Affairs (IPE) periodically ranks tech companies on their environmental and human rights performance in China. The fourth such ranking contains some surprises.

"The Global 100 Most Sustainable Corporations in the World is an annual project initiated by Corporate Knights, the magazine for clean capitalism…with three strategic partners to identify…the global corporations which have been most proactive in managing environmental, social and governance (ESG) issues.  Launched in 2005, the annual Global 100 is announced each year during the World Economic Forum in Davos." ICT companies do not populate the top of this list like they do some others.

Newsweek has released its Green Rankings 2009. It provides a rank for each the 500 largest US companies and a "Green Score" normalized to a 100-1 scale. How did companies in industries of interest stack up?
