Buildings are the largest source of GHG emissions in Toronto today, accounting for 58 per cent of total emissions. The emissions stem from the burning of fossil fuels, primarily natural gas, for heating, cooling and hot water. To reach net zero emissions by 2040, we must eliminate the use of fossil fuels as much as possible and switch to cleaner energy sources such as electricity and renewable energy.

What is a Net Zero Building?

In addition to using electricity and renewable energy as energy sources for heating, cooling and hot water, buildings must also be insulated properly from attic to basement, and have energy efficiency windows and doors.
