← Prices that reflect Cost

What did that shop really cost?

Photograph your receipt. We read the products, apply the same lifecycle emission factors as the calculator on the front page, and show the CO₂ damage cost at the bottom of the screen.

1 — The receipt

The photo is read on this device. Nothing is uploaded, and no account is involved.

2 — What we found

Every quantity is editable. Anything marked assumed is a typical pack size, because the receipt line never said how much.

Nothing yet. Scan a receipt, or add a product by hand below.

3 — The carbon price

The same range the front page uses. The higher the price, the stronger the behavioural push — and the more redistribution it demands.

How rough is this? Rough. OCR misreads receipts, shop wording is ambiguous, and a product name rarely tells you the weight. The figure is an order-of-magnitude answer to “what would this basket cost if the damage were in the price”, not a tax assessment. Correct the quantities and it gets a good deal closer.
