公式
How to Calculate Plastic Reduction Impact
Reducing single-use plastics saves resources and prevents pollution.
Average Item Weights
Formula
Items Reduced = Weekly Items * 52 * Reduction %
Weight Saved = Items * Average Weight
Each pound of plastic prevented saves about 3 lbs CO2 and 0.2 gallons of oil.
计算示例
Reducing 10 bags, 7 bottles, 5 containers per week by 75%.
- 01Total annual: (10 + 7 + 5) * 52 = 1,144 items
- 02Items reduced: 1,144 * 75% = 858 items
- 03Plastic saved: 858 * 0.025 = 21.5 lbs
- 04CO2 saved: 21.5 * 3 / 2,204.6 = 0.029 metric tons
