How to Calculate Plastic Reduction Impact

Reducing single-use plastics saves resources and prevents pollution.

Average Item Weights

  • Plastic bag: ~0.02 lbs (8 grams)
  • Plastic bottle: ~0.03 lbs (14 grams)
  • Food container: ~0.03 lbs (15 grams)
  • 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.

    Example Calculation

    Reducing 10 bags, 7 bottles, 5 containers per week by 75%.

    1. 01Total annual: (10 + 7 + 5) * 52 = 1,144 items
    2. 02Items reduced: 1,144 * 75% = 858 items
    3. 03Plastic saved: 858 * 0.025 = 21.5 lbs
    4. 04CO2 saved: 21.5 * 3 / 2,204.6 = 0.029 metric tons
