About this tool
Log the single-use plastic you avoid each week and see the weight, CO2e and money you save over a year.
The Plastic Reduction Tracker converts the single-use items you refuse each week into grams of plastic, kilograms of CO2e and money saved, then projects the habit across a full year. It uses average item masses — a 500 ml PET bottle is about 9.9 g, a carry bag about 5.5 g — and a cradle-to-grave factor of roughly 6 kg CO2e per kg of virgin plastic covering both production and end-of-life. It is built for anyone running a personal, family or office plastic-free challenge who wants a number instead of a vague feeling.

Every avoided item is priced in grams, so small swaps and big ones are compared honestly.
The same log produces a CO2e figure and a rupee saving, which makes the case to a sceptic.
A sorted table shows which single item contributes most of your avoided weight.
A standard 500 ml PET water bottle weighs about 9.9 g empty, and the cap and label add roughly 2 g more. Refusing six of them a week works out to around 3.1 kg of plastic a year — close to a sixth of the global average per-person single-use footprint.
About 6 kg of CO2e per kilogram of virgin plastic avoided. Roughly half comes from extracting and converting the resin and half from incineration at end-of-life, since plastic is about 80% carbon by mass. Recycled or landfilled plastic scores lower, so treat the figure as a planning estimate.
Anything designed to be used once and discarded: bottles, carry bags, straws, cutlery, cups and lids, sachets, cling film and takeaway containers. India's 2022 rules ban several of these categories outright, including straws, cutlery and thin carry bags below 120 microns.
It uses typical Indian retail prices for the item you would otherwise buy — around ₹20 for a bottle of water, ₹8 for a takeaway cup. It does not subtract the cost of the reusable alternative, so a ₹600 steel bottle pays for itself once you have skipped about thirty bought bottles.
