Cooling systems (estimated capacity) | Refrigeration capacity (Tons) | 18,500 | 18,821 | 17,744 | N/A | -1,077 | -756 | |
Generators (estimated capacity) | Kilowatt-hours (kWh) | 22,964 | 21,575 | 21,683 | N/A | +108 | -1,281 | |
Storage tanks | Number | 261 | 262 | 250 | N/A | -11 | -12 | |
Capacity (L) | 613,873 | 613,223 | 553,876 | N/A | -59,347 | -59,997 | ||
Consumption | Energy | kWh equivalent/ sq. ft | 32.38 | 33.9 | 32.2 | 36.53 | -0.18 | -1.7 |
Water | Litres / sq. ft. | 61.9 | 79.2 | 78.6 | 89 | -0.6 | +16.7 | |
Emissions | Air emissions | Total kg of CO2 equivalent | 56,874,264 | 53,276,050 | 47,272,681 | N/A | -6,003,369 | -9,601,583 |

Travel emissions* | Total CO2 emissions in kg / employee** | N/A | N/A | 708.7 | Not available | N/A | N/A | |
kg CO2 / rental vehicle | N/A | 94.79 | 107.24 | Not available | 12.45 | N/A | ||
Non-hazardous waste | Diversion rate (%) | 61.6 | 69.6 | 66*** | 90 | -3.6 | +4.4 | |
Hazardous waste | Quantity (mT) | 59.3 | 137.02 | 277.9**** | N/A | +140.88 | +218.6 |
* New data for 2012-2013
** Value normalized against number of permanent full time employees as of March 31 2013 (8,265)
*** Reduction of the diversion rate is due to an increase of waste quantities at the Montreal site. We expect that this is a one-time increase, and not a trend that will continue in future years.
**** Data does not include e-waste and scrap metal collected by the Transmission Division
See the Impact and reporting section for more information about our ongoing efforts to address each of these environmental issues.
