CarbonGuru bởi CarbonGuru

Know your carbon footprint. Act on it instantly.

CarbonGuru calculates the carbon footprint of any goods, services, or business activities you provide information about — product pages, shopping carts, email receipts, or pasted text. No spreadsheets, no guesswork. Just click the extension and get a clear CO₂e estimate in seconds, with the option to offset or fund carbon removals right from the results.

HOW IT WORKS

1. Analyze any product, service, or activity
Click the CarbonGuru button on any product page or shopping cart. The extension reads the page and sends it to our servers for analysis. It also works with Gmail purchase receipts and pasted text — anything that describes goods, services, or business activities.

2. Get a full lifecycle estimate
CarbonGuru uses AI to identify what you purchased, then applies established environmental science (EIO — Environmentally-Extended Input-Output analysis) to calculate the carbon footprint across the full product lifecycle: raw materials, manufacturing, packaging, shipping, and delivery to you. Results represent the cumulative footprint up to the point the item is in your hands, reported in kg CO₂e — the standard unit for comparing climate impact.

3. Offset securely
Every result comes with the option to purchase verified carbon offsets or carbon removals through leading providers CNaught and Stripe Climate. CarbonGuru facilitates the purchase securely on your behalf. Offset projects prevent or reduce emissions elsewhere (renewable energy, forest protection). Removal projects actively pull CO₂ from the atmosphere (direct air capture, biochar). All projects are certified by recognized standards like Verra, Gold Standard, and Puro.earth.

WHAT THE EXTENSION DOES

• Calculates carbon footprints for products, services, and business activities
• Works on thousands of online retailers — Amazon, REI, Walmart, Target, and more
• Scans Gmail purchase receipts for past orders
• Tracks your cumulative carbon footprint on a personal dashboard
• Lets you offset or fund carbon removals with one click
• Shows what drives each item's impact (industry classification, lifecycle context)

THE SCIENCE BEHIND IT

CarbonGuru's estimates are grounded in a well-known scientific method called EIO (Environmentally-Extended Input-Output) analysis. EIO models the entire economy as a web of industries — each one buying from others — and traces emissions through every link in the chain. This gives you a credible, full lifecycle footprint estimate even without access to factory data or supplier lists.

AI handles the messy part: reading product titles, receipt text, and web pages to figure out exactly what you bought and map it to the right category. The science handles the rest. AI provides speed and clarity; established environmental models provide accuracy and consistency.

WHAT WE COLLECT

The extension only sends data when you click the CarbonGuru button — it does not passively monitor your browsing. We collect the page content and URL of the product or cart you're analyzing, plus your account email. We do not store full page content after analysis.

OFFSETS & REMOVALS

CarbonGuru facilitates carbon offset and removal purchases through CNaught and Stripe Climate, leading verified carbon credit providers. Every purchase includes a certificate with project details, registry links, and retirement records. You choose between offset portfolios (lower cost, emission reduction projects) and removal portfolios (higher cost, direct CO₂ removal from the atmosphere).

Free to install. Free to analyze. Pay only if you choose to offset.
