Given 6,029,145 users, the app will eliminate a total of 1,984,660.364 tonnes of CO2 emissions (including transportation emissions), and 57,028,608 tonnes of water. This environmental impact is the same as taking 1,984,660 cars off the road for one year and will save the equivalent of 17,380.85 people drinking water over the same period (McGill, 2020). The estimation of environmental impact was calculated by multiplying the rate of CO2 emissions per ton of household waste by the estimated volume of food waste reduction. The water usage was calculated by multiplying the average water wasted per tonne of food waste (128 tonnes) with the total volume of food saved (Gooch et al., 2019).

Since the food that consumers buy is being used completely, consumers will require less food to be bought from grocery stores, resulting in less food production emissions. With 6,029,145 users, there will be 445,536 tonnes less food required, reducing transportation emissions by 35,642,880 to 40,098,240 tonnes of CO2 per year—assuming that each truck holds an average of 25 tonnes of food and the average trip for food transportation to Canada is 2500 km (Development and Peace, 2017).
