CarbonGuru
Carbon Footprint Calculator
Free
Know the carbon footprint. See the climate impact. Act instantly.
CarbonGuru brings real-time climate action to the places you already buy, read, and work — in your browser, inbox, files, documents, email, and alongside your AI agents.
Use the Safari extension to analyze product pages, shopping carts, online orders, Gmail messages, email receipts, pasted text, URLs, and business activity. CarbonGuru estimates the carbon footprint in kg CO₂e, shows the climate impact, and lets you act immediately with verified offsets or carbon removal.
Start free with 30 footprints every month, including AI agent access. Offsets and removals unlock more — act more, impact more.
HOW IT WORKS
1. See your footprints — know the climate impact
Click the CarbonGuru button on a product page, shopping cart, receipt, Gmail message, webmail page, order confirmation, supplier page, or any website with product, service, or activity information. You can also paste text, analyze URLs, upload documents, or use CarbonGuru through supported AI agents.
2. Get a lifecycle carbon estimate
CarbonGuru uses AI to understand what you provide, then applies established environmental science including LCA and EIO analysis to estimate the carbon footprint. Results are reported in kg CO₂e and represent the cumulative footprint up to the point the item is in your hands: raw materials, manufacturing, packaging, shipping, and delivery.
3. Act with offsets and removal
See the footprint, then act where you are — in the extension, by email, on CarbonGuru, or through your AI agent. Fund verified carbon offsets or carbon removal directly from the result. Offsets prevent or reduce emissions; removal projects actively pull CO₂ from the atmosphere.

PLANS AND ACCESS
Free to install and free to start. The free plan includes 30 footprints every month with AI agent access. Paid plans add comprehensive analysis, impact tracking, file uploads, automated email scanning, business imports, and automated carbon management. Offsets and removals unlock more footprints — positive action rewards more positive action.
THE SCIENCE BEHIND IT
CarbonGuru estimates are grounded in established environmental science. AI maps what you provide to environmental and economic models. EIO analysis traces emissions through the supply chain; lifecycle analysis estimates the cumulative footprint including materials, production, packaging, shipping, and delivery.
VERIFIED ACTION
Offset and removal options come from trusted providers including CNaught, Frontier, and Stripe Climate, certified by Gold Standard, Verra, Puro.earth, and Isometric. Every credit is traceable to a specific project and place.
WHAT WE COLLECT
The extension only sends data when you ask CarbonGuru to analyze something — it does not passively monitor your browsing. CarbonGuru may receive the page content and URL of what you analyze, plus your account email. We do not store full page content after analysis. See our full privacy policy at carbonguru.io/privacy-policy.
Free to install. Free to start. Pay only if you choose to offset, fund removal, or upgrade.
