Plan a plastic reduction: start from your current annual plastic use and model what percentage cuts save in kilograms, CO2e and items.
Estimates: savings assume the reduction is sustained and reusable replacements are used often enough to pay back their own footprint.
Plastic saved (kg/year)
How to use this tool
Use the Plastic Footprint tool first if you do not know your annual kilograms.
Try 25%, 50% or 75% and see what each actually saves — ambitious targets need concrete swaps.
A yearly saving can feel abstract; the monthly line makes it tangible.
Match the saving to real changes: a reusable bottle, bags and containers cover most household single-use plastic.
Formula & worked example
Cutting 30 kg a year by 50% saves 15 kg of plastic and about 45 kg CO2e a year, or roughly 1.3 kg less every month.
Limitations — read this before you rely on it
Savings assume the reduction is real and sustained, and that reusable replacements are used often enough that their own footprint does not cancel the saving. Production factors are estimates.
Frequently asked questions
That tool estimates your current use from weekly items. This one starts from a known annual total and models reductions against it.
For many households yes, with reusables for bottles, bags, cups and containers — but it needs habits, not just buying reusables once.
Only if rarely used. A reusable bottle or bag used dozens of times quickly beats single-use items on footprint.
Single-use and packaging plastic here. Durable plastic goods you keep for years are a different, much smaller annual flow.
Leave it blank or zero — the kilogram and CO2e savings still calculate, and only the items-avoided line is affected.
