PART OF YOUR WORKFLOW
For life every day, and business everywhere
Automated offsetting with agent-integrated data
Calculate the footprint of a single product, or a full quarter of purchasing across the whole company — then act on it. Cover your own operations, your supply chain: as much or as little of each as you choose.
Analyze business purchases, orders, and spend
Estimate the carbon footprint across your supply chain: products, services, vendor purchases, procurement records, expense data, shopping carts, order histories, and shipments — before or after checkout. Import your vendor spend and CarbonGuru turns those dollars into carbon.
Measure the tools you build and run on
Know the impact of the tech stack behind your products — model APIs, cloud compute, SaaS subscriptions — and the systems that keep operations running.
Import files and business documents
Upload CSVs, Excel files, PDFs, invoices, receipts, and statements to turn unstructured activity into carbon-footprint records.
Put your AI agent to work
Connect Claude, ChatGPT, or your own agent to any linked source and get per-item and total footprint, climate cost, and one-step offsetting for the whole set.
Automate email and document analysis
Use email scanning, browser analysis, and scheduled imports to build repeatable carbon intelligence workflows across teams.
Find high-impact categories and better alternatives
Identify which products, vendors, departments, activities, or purchase categories contribute the most to footprint totals, then compare suppliers, SKUs, services, or alternatives using carbon impact alongside cost and operational criteria.
Offset or remove emissions at any scale
Take verified climate action on individual transactions, vendor groups, shipments, or departments — or set a monthly offset that scales as you ship.
Create transparent records of action
Track analyses, actions, offsets, removals, methods, and project-backed climate activity for internal review, stakeholder communication, or customer-facing reporting.

How CarbonGuru works
CarbonGuru covers almost anything bought, sold, or processed in the global economy, and at almost any scale — from a single t-shirt to a university’s annual operations.
Fast, accurate analysis
Detailed estimates in seconds, from everyday sources: product pages, shopping carts, email receipts, documents, and plain text — on Amazon, local boutiques, webmail, and more.
Lifecycle analysis, grounded in established science
AI identifies what you purchased, then Environmentally-Extended Input-Output (EIO) analysis calculates the footprint across the full lifecycle — raw materials, manufacturing, packaging, shipping, and delivery. Every estimate is the cumulative footprint up to the point the item is in your hands.
Works everywhere, in any language
From Amazon to local boutiques, email receipts to product pages and business documents — automatically, in nearly 120 languages, with detailed economic and environmental models for over 140 countries.
How we calculate →
Clarity you can use
Understand the climate impact of what you buy and do, in depth, without needing to be an expert. Every footprint comes with the context that makes it meaningful — not just a bare number.
A standard, global unit
Results are reported in kg CO₂e — the internationally recognized measure — alongside a real-world climate-impact cost, so the figure is easy to understand anywhere in the world.
Relatable comparisons, built in
CarbonGuru provides relatable comparisons for many items automatically, from common cost-of-living indexes.
Review, track, and stay transparent
A running dashboard tracks your footprints and the actions you take — right from the result, no extra steps or tools. Every figure shows its method and sector classification, so the authority is on the page, not hidden.

Short video walkthroughs in the browser, inbox, and with your AI agent.
Immediate, verified action
Turn awareness into impact with vetted offsets and removals you can fund immediately — reviewed and acted on right from the result, with the credit purchased and retired for you automatically.
Carbon Offsets
Prevent or reduce emissions elsewhere — nature-based (avoided deforestation, reforestation, regenerative agriculture), community (clean cookstoves, renewable energy), and industrial avoidance (methane capture, landfill gas).
Carbon Removals
Actively draw CO₂ back out of the atmosphere — biochar sequestration, enhanced rock weathering, direct air capture, and ocean-based CDR.
Verified, traceable projects
Credits are sourced through CNaught, Frontier, and Stripe Climate — working with leading registries including Gold Standard, Verra (VCS), Puro.earth, and Isometric, with independent third-party auditing, transparent monitoring, and rigorous additionality testing. Every credit is traceable to a specific project and place.
Personalized, and at any scale
Fund the exact action you choose, tailored to what you analyzed. Quantities scale from a single item (under 1 kg CO₂e) to bulk, per-tonne actions — act on one purchase, offset an entire shipment, or remove carbon for a group of suppliers, immediately from the result.

CarbonGuru’s Purpose
Real impact, within reach — for anyone.
Whether it’s your regular grocery run or your company’s monthly shipping, see the carbon footprint of what you buy, make, and do — and act on it directly, for as little as pennies per kilogram of carbon.
Offsetting is one of the most practical ways to make a difference — affordable enough to do as you go, and effective enough to make your overall impact a positive one.
¢ / kg
Genuinely affordable
Offsetting costs only pennies per kilogram of CO₂ — usually a few percent of what you paid. It’s affordable enough to balance impact as you go.
A new phone, or a container shipment — the math works the same at both scales.
net +
Go all the way to positive
Balancing is just the start. For a little more, you can go net-positive — and by funding removals, help build the capacity to draw carbon down for years to come.
A genuinely positive footprint, or a carbon-balanced operation — your choice of how far.
1 → all
Your action helps everyone
We all share one atmosphere, so the good you do reaches far beyond you. Offsetting is rare that way: a single decision whose benefit belongs to everyone.
Cleaner air for your family, your customers, your community — all at once.
See your impact, act on it, and watch it add up — for everyone.
