PART OF YOUR WORKFLOW
For life every day, and business everywhere
Understand and offset directly, without hassle
CarbonGuru instantly calculates the footprints and climate impact for groceries and take-out, kids’ clothes and summer activities, tickets for travel with friends and family — or point CarbonGuru at weekly and monthly purchases that repeat, and schedule offsets that renew every month. Manage the carbon impact of ordinary life with a setting, not a chore.
Shop and compare products — choose with climate visibility
See the carbon footprint of products, shopping carts, wishlists, orders and receipts, before or after you buy. Compare products in and across baskets.
Offset individual purchases and specific sellers, a basket of items, and complete categories
Offset one product, all your shopping carts from the same seller, or a full month of purchases with verified offsets or removals.
Turn every receipt into action
Forward or scan email receipts and get item-level carbon footprints, climate cost, and confirm offset/removal without leaving your inbox.
See your history of action and footprints over time, by source and category
Summarize your footprints, review the items you’ve offset or removed, and visualize your climate action over time.
Have your AI agent analyze for you
Ask Claude, ChatGPT, or another MCP-compatible agent to fetch and footprint products, summarize your history, estimate offsets, and confirm your positive activity.
Make climate action automatic
Tell your agent to set up repeatable workflows for scheduled purchases, receipts, carts, or email activity to make analysis and offsetting automatic instead of manual.
Publish and share footprints and climate action
Turn any footprint or offset into a public page with a shareable link and preview card, as proof of action others can see.
Relatable impact context
Every footprint comes with real-world equivalences and reference-product comparisons that make its climate cost legible without expertise.
Personal and global dashboards
Track your own footprints and offsetting activity over time, alongside aggregate community and global impact views.

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.
