The company made the announcement as it released its first combined financial and corporate responsibility report, which revealed that Verizon reduced its carbon intensity by 30 percent from 2009 to 2011. This means the company needs another 20 percentage point decrease to reach its 2020 goal.
Environmental Leader will review the report in detail soon.
Verizon’s carbon efficiency metric, unveiled in 2011, divides the company’s carbon emissions in metric tons by the amount of data that it transports, in terabytes. The carbon emissions used in the metric include electricity, building fuels and vehicle fuels.
The company says this metric allows it to accurately quantify the impact of all its environmental initiatives for the first time. Tests using the metric showed a 15 percent improvement in the company’s carbon efficiency from 2009 to 2010.
Last year the company announced a goal of increasing its carbon efficiency by 15 percent from 2010 to 2011, and Verizon says it achieved this aim, with a reduction of just under 17 percent.
Also in 2011, the company announced that it had implemented Polargy’s PolarPlex containment system across nearly 1 million square feet of data centers, achieving a 7.7 percent improvement in energy efficiency.
