Carbon Sight turns your camera into a carbon-footprint scanner. Point it at a product, a meal, a receipt, a label, or a barcode. In about three seconds you get a real, cited carbon number — plus visceral context like "that's 20 single-use water bottles" or "3 kitchen trash bags of decomposing food waste" so it actually means something. WHY IT'S DIFFERENT Most carbon calculators are black boxes. Carbon Sight isn't. Every score you see traces back to a specific published life-cycle assessment, government emissions inventory, or peer-reviewed study — Nature, Science, IPCC, The Lancet, EPA, USDA. The methodology is public. The sources are cited. You can click through and read them yourself. We built it because we were sick of vibes-based sustainability claims. If you're going to change what you buy, you deserve real numbers. HOW IT WORKS Take a photo of packaging, a menu, a receipt, or anything with a carbon footprint. AI vision identifies it in seconds. Or type it — "iPhone 15 Pro," "Beyond Burger," "Diet Coke 12oz can" — anything. Get a score in kg CO2e with a confidence range and grade against similar products. See the sources — every LCA and paper used to compute it, with clickable citations. Compare lower-impact alternatives. WHAT WE MODEL Food and drinks. Consumer electronics. Clothing and footwear. Packaging (aluminum, glass, PET, paper, corrugated cardboard). Household goods, cleaning products, cosmetics. Full receipts and grocery hauls. 10,000+ pre-scored catalog items.
