Plastic Footprint Calculator
Track how much plastic you use in daily life and convert it into carbon emissions, ocean pollution equivalents, and recycling benefits.
500 ml PET water or soda bottle (~20 g).
Thin HDPE grocery bag (~5 g).
Clamshell or meal container made from PP or PET (~30 g).
Air pillows, bubble wrap, tape per package (~120 g).
Combined weight of one straw or utensil set (~2 g).
Percent of your plastic waste that is actually recycled.
Weekly plastic use
359 g
Annual plastic footprint
18.67 kg
Annual CO₂ emissions
112.01 kg CO₂e
Equivalent to 277.25 miles of driving.
Recycling savings
8.96 kg CO₂e avoided
Assumes recycling saves 40% of production emissions.
Potential ocean pollution
933.4 bottles worth of plastic
How to Use This Calculator
Estimate your weekly usage
For each plastic item, enter how many you typically use or receive every week.
Adjust weights if needed
Use the provided averages or replace them with actual packaging weights from your household.
Set your recycling rate
Enter the percentage of plastics you properly recycle to see how much CO₂ you avoid.
Formula
Annual Plastic (kg) = Σ(Weekly Units × Weight × 52) ÷ 1000
Annual Emissions = Annual Plastic × 6 kg CO₂e/kg
Recycling Savings = Emissions × Recycling Rate × 0.4
Example: 5 bottles/week × 20 g × 52 = 5,200 g = 5.2 kg plastic. Emissions = 5.2 × 6 = 31.2 kg CO₂e.
Adjust the 6 kg CO₂e factor if you have supplier-specific lifecycle data.
About the Plastic Footprint Calculator
Plastic pollution is a global concern—from production emissions to microplastics in oceans. This calculator gives you a quantified snapshot of your household’s plastic use and highlights the benefits of recycling and reduction.

Frequently Asked Questions
Do bioplastics count?
Bioplastics often have similar end-of-life challenges. Include them unless you have specific composting or emission data to differentiate.
Is 6 kg CO₂/kg accurate for all plastics?
It’s an average cradle-to-grave figure. Adjust the factor if you know the polymer type or recycling method used.
What about microplastics from clothes?
This tool focuses on solid items. Include synthetic clothing by estimating grams shed per wash if you have that data.
How can I reduce my footprint quickly?
Switch to reusable bottles and bags, request minimal packaging for online orders, and choose restaurants that use compostable take-out containers.
