Annual Cost of Food Waste vs Weekly Food Waste
Formula
## How to Calculate Food Waste Impact About 30-40% of food in the US is wasted, with enormous environmental and financial costs. ### Formula **Annual Cost = Weekly Waste * 52 * Cost per lb** ### Environmental Impact per Pound of Wasted Food - **CO2**: ~3.8 lbs CO2e (includes production, transport, and landfill methane) - **Water**: ~108 gallons (virtual water used in production) - **Land**: ~2.5 sq ft of farmland The average American wastes about 219 lbs of food per year.
Exemplo Resolvido
A 3-person household wasting 5 lbs of food per week at $2.50/lb average.
- 01Annual waste: 5 * 52 = 260 lbs
- 02Annual cost: 260 * $2.50 = $650
- 03CO2: 260 * 3.8 / 2,204.6 = 0.45 metric tons
- 04Water wasted: 260 * 108 = 28,080 gallons
