Environmental GRI Performance Indicators
EN19 – Emissions of ozone-depleting substances by weight.
We have eliminated ozone depleting substances from most of our operations and have had no reportable releases.
While we do continue to use halocarbon-containing equipment (in some vehicles, drinking water fountains, refrigeration, and air conditioning systems), as well as Halon-containing equipment (fire extinguishers) at some facilities, we no longer have any infrastructure containing a significant quantity of ozone depleting substances.
Our Performance
Liquids Pipelines finalized and implemented in 2006 an Ozone-depleting Substances Environmental Management Plan for its Canadian operations. The plan includes phase-out of Halon-containing fire extinguishing equipment and a commitment to find alternatives to minimize our use of other ozone-depleting substances. We review the plan every three years and update it as necessary to reflect changes in the applicable legislation. In 2007, all Canadian employees received Ozone-depleting Substances and Environmental Management Plan training. We also decommissioned our Norman Wells System’s fixed Halon fire suppression system, the last fixed Halon system in Enbridge’s Canadian operations.
