Part 1 — Get set up

Step 1: Create your free account

1. Go to Get Started and choose the path that fits you — Personal (everyday life and work) or Business (professionals, teams, and companies).
2. Create your account with your email address. Every account starts on the free Lead tier — no card required.
3. Confirm your email. Open the message from CarbonGuru and set your password. (Check spam if it hasn’t arrived in a few minutes.)

✅ Checkpoint: You’re logged in to CarbonGuru on the free Lead tier.

Step 2: Install the browser extension

The extension is how you measure and offset anything in your browser — click a button or select text on any product, catalog, shopping cart, receipt, or webmail message. Install it from your browser’s official store:

1. Open the store link for your browser (above).
2. Click “Add” / “Get” / “Install” and approve the permissions prompt. On Chrome, Brave, Arc, Firefox, and Edge that’s it — the CarbonGuru icon appears in your toolbar.

Enabling CarbonGuru in Safari (macOS, iPhone & iPad)

Safari delivers the extension inside a small CarbonGuru app from the App Store. After you install that app, switch the extension on:

On a Mac:

1. Install CarbonGuru from the Mac App Store and open the app once so Safari registers the extension.
2. Open Safari → Settings (⌘,) → Extensions.
3. Tick CarbonGuru to turn it on, and allow the website permissions it requests.
4. Click the CarbonGuru icon in Safari’s toolbar and sign in.

On iPhone & iPad:

1. Install CarbonGuru from the App Store.
2. Open Settings → Apps → Safari → Extensions (on iOS/iPadOS 17 and earlier: Settings → Safari → Extensions).
3. Tap CarbonGuru, turn it On, and set the site permissions to Allow.
4. In Safari, tap the ᴀA button in the address bar → Manage Extensions to confirm CarbonGuru is enabled, then open it and sign in.

✅ Checkpoint: The CarbonGuru icon appears in your browser toolbar (on Safari, after you enable it in Settings).

---

Step 3: Sign in and pin the extension

1. Click the CarbonGuru icon in your toolbar. (Chrome/Edge: click the puzzle-piece icon 🧩 and pin CarbonGuru so it’s always visible. Firefox: right-click the toolbar → Customize to pin it.)
2. Sign in with the account you created in Step 1.

✅ Checkpoint: The extension shows you’re signed in and ready.

Step 4: Run your first analysis

Open any product page, shopping cart, or order confirmation and try one of these:

• Click the CarbonGuru button that appears on supported product and cart pages.
• Select any text on a page (a product name, a line item, a receipt) and send it to CarbonGuru.
• Open the extension and paste a product URL or a description.

CarbonGuru returns three paired metrics for everything it analyzes: the carbon footprint (kg CO₂e), the social cost (the real-world damage in dollars), and the offset cost (usually just pennies per kilogram to balance it).

✅ Checkpoint: You’ve analyzed your first item and can see its footprint.

---

Step 5: Review your footprints and offset them

1. Open My Carbon Footprints to see every product and cart you’ve analyzed, with full footprint breakdowns.
2. Add offsets or removals to your cart directly from any footprint — in the extension, by email, or on the site.
3. Check out in one step. Verified carbon credits are retired for you automatically, sourced through CNaught, Frontier, and Stripe Climate with leading registries (Gold Standard, Verra, Puro.earth, Isometric).

✅ Checkpoint: You’ve measured, seen, and acted on a footprint. That’s the whole loop.

Part 2 — Activate your plan

Every tier can do everything below its own line, plus what it unlocks. Work through the checklist for your plan — each item links to how-to instructions. Not sure which tier you’re on, or want more? See Plans & Pricing.

Analyses run on a monthly rolling window and also reset early once your cumulative offset/removal purchases reach your tier’s threshold — so regular offsetting keeps your allowance topped up.

✅ Lead — Free

Personal · 30 analyses / month · resets at $2 in purchases

✅ Plus — $5/mo

Personal · 200 analyses / month · resets at $5 in purchases

Everything in Lead ✓ — plus turn on:

✅ Pro — $10/mo Most Popular

Personal & Business · 500 analyses / month · resets at $10 in purchases

Everything in Plus ✓ — plus turn on:

✅ Prime — $20/mo

Business · 1,250 analyses / month · resets at $20 in purchases

Everything in Pro ✓ — plus:

Part 3 — Feature how-tos

Connect Gmail

CarbonGuru can scan your inbox for order confirmations and measure them automatically — no need to visit each cart page. It uses Google OAuth with read-only access.

1. Open the Gmail & Email Settings page.
2. Click Connect Gmail Account and authorize CarbonGuru in the Google popup.
3. Your receipts are found and processed automatically. (On Pro and above, new receipts are scanned as they arrive.)

Email forwarding (any inbox)

Prefer not to connect Gmail, or use another provider? Forward receipts from any account.

1. On the Gmail & Email Settings page, generate your unique token (format CG-XXXXXXXX).
2. Forward order receipts to email_processing@carbonguru.io with your token in the subject line.
3. CarbonGuru analyzes the receipt and adds it to your dashboard.

File import & export

Import (Plus and above): Upload an accounting or finance file and CarbonGuru detects the format, runs the analysis, and returns your file with carbon columns added.

1. From your account, choose to upload a file (CSV, Excel, PDF, or documents; business accounting/invoice formats on Pro).
2. Download the enriched file, or view the results on your dashboard.

Export (Plus and above): Turn any completed analysis session into a shareable file — CSV, XLSX, JSON, or PDF — from the session view in your account. Your mapped data stays saved, so you can regenerate an export any time, even after the original file is gone.

Connect your AI agent

CarbonGuru works directly inside AI assistants that support connectors (like Claude) and as a custom GPT. Analyze products, search your history, get offset quotes, and — on Pro and above — automate imports and offsetting through chat.

1. In your assistant, add the CarbonGuru connector using https://carbonguru.io/mcp.
2. Authorize with your CarbonGuru account when prompted.
3. Ask your assistant to analyze a product, scan a receipt, or offset a footprint — it runs the real CarbonGuru tools and returns real numbers.

Troubleshooting & support

The extension isn’t in my toolbar

• Chrome/Edge: click the puzzle-piece icon 🧩 and pin CarbonGuru.
• Firefox: open about:addons, confirm CarbonGuru is enabled, then right-click the toolbar → Customize to add it.
• Safari: open Safari → Settings → Extensions and switch CarbonGuru on. If it isn’t listed, open the CarbonGuru app once from your Applications folder.

Extension updates

Because CarbonGuru is installed from the stores, it updates automatically — there’s nothing to download or reinstall.

I forgot my password

Use the password reset link, enter your email, and follow the link you receive.

Gmail says connected but isn’t scanning

• Disconnect and reconnect on the Gmail & Email Settings page.
• Confirm CarbonGuru still has read access at Google Account permissions.
• Large inboxes can take a little while for the first scan.

Still stuck?

Email support@carbonguru.io with your username, your browser and OS, and a short description of the problem and what you’ve tried.
