Sustainability

Toronto is a city that cares about sustainability and is committed to becoming the model of an energy efficient city of tomorrow.

Toronto has developed a dynamic sustainability strategy that integrates and balances the competing expectations of the present generation without compromising those of future generations.

Toronto has reduced its greenhouse gas emissions by 25% since 1990, with a total reduction goal of 30% by 2020, and 80% by 2050. This reduction is due, mostly, to a 52% reduction of emissions from electricity production, and a 61% reduction from improved waste management practices. Over four years, from 2008-2012, the city reduced its citywide greenhouse gas emissions by 4,000,000 tonnes. (City of Toronto, 2014)

As cities around the world work to define urban energy systems to meet growing demand, Toronto is leading the way with the Clinton Climate Initiative as part of the C40 Program (www.c40cities.org) to solve sustainability and climate issues. The C40 includes a diverse group of cities who have pledged to work together to reduce greenhouse gas emissions.

Toronto's goal to achieve a clean, reliable and affordable energy supply is being met through various other initiatives, including:

  • EnWave's Deep Lake Water Cooling System, the largest of its kind in the world, cooling many major downtown office towers, institutions and hospitals, including City Hall. This revolutionary system reduces the energy needed to cool these buildings by 90%.
  • North America's first urban wind turbine, the largest solar installation in Canada, and the country's first municipally owned tri-generation hydrogen system, located at Exhibition Place. These three energy production facilities all help supply energy needs at Exhibition Place.
  • Toronto's Green Roof initiative, providing economic benefits to the city, particularly in the areas of storm water management and the reduction of heat produced in dense metropolitan areas. To learn more about Toronto's Green Roof initiative, see http://www.toronto.ca/greenroofs/index.htm.
  • The Tower Renewal Project, which combines green technology with neighbourhood revitalization in order to make 1,000 of the city's older towers more energy efficient. This is an important energy conservation initiative as Toronto has the 2nd highest concentration of towers in North America.
