CarbonGuru

Know your carbon footprint. Act on it instantly.

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. CarbonGuru calculates the carbon footprint and climate impact of any goods, services, or business activities you provide information about — product pages, shopping carts, online orders, Gmail messages, email receipts, pasted text, URLs, and uploaded documents. No spreadsheets, no guesswork. Just click the extension and get a clear CO₂e estimate alongside the projected climate damage in dollars, with the option to offset or fund carbon removals right from the results. 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. Same insight, same impact; exactly where you need it. 2. Get a full lifecycle estimate and climate impact assessment CarbonGuru uses AI to understand the item, service, receipt, page, cart, file, or document you provide, then applies established environmental science including LCA and 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. Then CarbonGuru goes a step further: it translates your footprint into a dollar estimate of the long-term climate damage — the real-world cost of those emissions in terms of rising temperatures, extreme weather, crop losses, health impacts, and economic disruption over decades to come. This figure, based on the Social Cost of Carbon used in federal climate policy, puts a concrete price tag on the climate consequences of everyday purchases and business decisions. 3. Act with offsets and removal — close the gap See the footprint, then act where you are — in the extension, by email, on CarbonGuru, or through your AI agent. Every result comes with the option to purchase verified carbon offsets or carbon removals through trusted providers. CarbonGuru facilitates the purchase securely on your behalf. Offset projects prevent or reduce emissions, including renewable energy, forest protection, methane capture, and clean cookstoves. Removal projects actively pull CO₂ from the atmosphere, including direct air capture, biochar, enhanced rock weathering, and other carbon removal methods. All projects are certified by recognized standards like Verra, Gold Standard, Puro.earth, and Isometric. WHAT CARBONGURU DOES • Calculates carbon footprints for products, services, purchases, receipts, orders, documents, and business activities • Shows the long-term climate damage of each item in dollars • Works from product pages, shopping carts, Gmail, webmail, pasted text, URLs, and uploaded files • Supports browser-based analysis, email analysis, CarbonGuru console workflows, and AI agent access • Tracks cumulative carbon footprint and climate impact over time • Lets you offset or fund carbon removal immediately • Shows what drives each item's impact (industry classification, lifecycle context) • Supports personal use, work activity, and small-business carbon management • Works automatically in nearly 120 languages • Uses global economic and environmental models covering over 140 countries PLANS AND ACCESS CarbonGuru is free to install and free to start. The free plan includes 30 footprints every month with AI agent access. Paid plans add comprehensive analysis, activity and impact tracking, file uploads, automated email scanning, business imports, and automated carbon management across daily life, work, and business. Offsets and removals unlock more footprints — positive action rewards more positive action. THE SCIENCE CarbonGuru's estimates are grounded in two well-established scientific frameworks. Carbon footprint calculations use 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. Climate impact calculations use the Social Cost of Carbon (SC-CO₂), the same metric used by the U.S. federal government and international bodies to evaluate the economic damage caused by each additional ton of CO₂. It aggregates projected costs across agriculture, human health, property damage, energy systems, and ecosystem disruption over the lifetime of those emissions. The result is a single dollar figure that represents the real long-term harm of your carbon footprint — making the invisible consequences of emissions concrete and comparable. 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 and economic models provide accuracy and consistency. VERIFIED ACTION CarbonGuru sources offset and removal options through trusted providers, including CNaught, Frontier, and Stripe Climate. Projects are certified by recognized standards and registries including Gold Standard, Verra, Puro.earth, and Isometric, with independent auditing, monitoring, and additionality requirements. Every credit is traceable to a specific project and place, so you can verify how and where your action creates impact. WHAT WE COLLECT The extension only sends data when you click the CarbonGuru button — it does not passively monitor your browsing. Depending on what you choose to analyze, CarbonGuru may receive the page content and URL of the product, cart, receipt, email, document, or text you provide, plus your account email. We do not store full page content after analysis. See our full privacy policy at https://carbonguru.io/privacy-policy. Free to install. Free to start. Pay only if you choose to offset, fund removal, or upgrade for more automation and capacity.
