1. Data reflected in the table is as of March 31, 2015.
* Increase is attributed to current transition from older sites to newer ones.
** Normalized value for a BOMA BESt certified building according to 2012 water benchmarking pilot report by Real Pac
*** Value normalized against total number of permanent, temporary, short-term and contract employees as of March 31, 2013 (9,065), and represents air and rail travel
**** Value normalized against total number of permanent, temporary, short-term and contract employees as of March 31, 2014 (9,136), and represents air and rail travel
***** Value normalized against total number of permanent, temporary, short-term and contract employees as of March 31, 2015 (7,700), and represents air and rail travel
****** Data does not include e-waste and scrap metal recycled by the Transmission Division
