Each user’s carbon emissions are calculated using conservative estimates. Emissions factors are national or provincial averages. Tree Canada used the following sources to ensure calculations are not underestimated.
Note: Carbon footprints reported by the app are conservative estimates and do not capture all factors that contribute to an individual’s complete carbon footprint. The app’s goal is to increase awareness of your footprint, enable you to take action – in the app and beyond – to reduce your footprint, and inspire others to make lifestyle changes to help address climate change.
