Sustainability

From 2006 to 2020, we achieved a 91.8% reduction in our greenhouse gas emissions, the result of careful data analysis and thoughtful planning. 

Here are just some of the ways we’ve lowered our emissions recently:

  • Retrofitted to LED lighting
  • Installed a ventilation-on-demand control system for our kitchen
  • Installed a food-digesting system to maximize our waste diversion rate
  • Upgraded to low-flow plumbing fixtures

And our work is far from done. In the coming years, we’ll be eliminating ozone-depleting refrigerants from our operations, and introducing best-practices training for energy and water conservation—and thinking up innovative ways to decrease our footprint even further!

Emissions

This bar graph shows that the CN Tower has reduced its greenhouse gas emissions by 45,792 metric tons since 2006, the equivalent of taking 9,954 cars off the road for one year.
  • A reduction of 45,792 metric tonnes of GHG emissions since 2006
  • Equivalent to taking 9,954 cars off the road for one year

Water consumption

This bar graph shows that the CN Tower has reduced its water consumption significantly since 2005—with 71 million litres of water conserved since 2015, the equivalent of 28 Olympic swimming pools.
  • A reduction of more than 71 million litres of water since 2015
  • Equivalent to 28 Olympic swimming pools

Hydro 

This bar graph shows that the CN Tower has reduced its electricity consumption by more than 59 million kilowatt hours between 2006 and 2019, the equivalent to 394 million kilometres driven by electric passenger vehicles.
  • A reduction of more than 59 million kilowatt hours since 2006
