Your checkout is never modified. * **No code**: the plugin places the display card and reports paid orders for you. Products, offsets, payment, and consent are managed in your CarbonGuru panel. **How it works** 1. One-click connect: sign in to CarbonGuru, accept the merchant terms, and your keys are provisioned automatically — nothing to copy or paste. 2. Your product catalog is analyzed for carbon footprints (within your plan’s allowance; nothing is analyzed or charged without your confirmation). 3. You review each footprint and switch on the products you want live — from your WooCommerce Products list or your CarbonGuru panel. 4. The footprint card appears on your product pages automatically. 5. When an order is paid, the plugin reports its line items; with automatic offsetting on, the order’s carbon is offset and billed to the payment method saved in your CarbonGuru account. **External service disclosure:** this plugin communicates with carbonguru.io. Terms of service: https://carbonguru.io/merchant-terms/ — Privacy policy: https://carbonguru. io/privacy/ * Product pages load the CarbonGuru display card script. The card sends only your embed key and the product page address — never anything your customer types, and no cookies are set. * When an order is paid, the plugin sends the order’s line items (product identifiers and quantities) and an order reference to your CarbonGuru merchant account — no customer names, emails, or addresses. * Offset purchases are billed to the payment method saved in your CarbonGuru account. Retired carbon cannot be un-retired — offset purchases are non-refundable. ## Screenshots [⌊The carbon footprint card on your product pages — shown to shoppers, offset at purchase.⌉⌊The carbon footprint card on your product pages — shown to shoppers, offset at purchase.⌉[ The carbon footprint card on your product pages — shown to shoppers, offset at purchase.

Install and activate the plugin (USD stores; WooCommerce 8.0+; single-site — network activation is unsupported). 2. Open WooCommerce CarbonGuru and connect your CarbonGuru account. 3. Set up payment and activate products in your CarbonGuru panel. 4. Turn on automatic offsetting. Done — every paid order is offset automatically. ## FAQ ### Do my customers pay for the offsets? No. Offsetting is merchant-settled: purchases are billed to the payment method saved in your CarbonGuru account. Your shoppers never see a charge, a fee, or a payment surface, and your cart and checkout are never modified. ### Where do the carbon footprints come from? Each product is individually analyzed by CarbonGuru from your actual product data— not estimated from order totals or category averages. You review every footprint before switching a product on; nothing displays and nothing is offset until you do. ### What does the plugin change on my store? Two things only: it renders the footprint card on product pages for products you’ve switched on, and it reports paid orders to your CarbonGuru account. It adds no scripts to your cart or checkout, sets no cookies for your shoppers, and sends no customer personal data. ### Does it work with my theme? Yes — block and classic themes. You can choose where the card renders relative to the add-to-cart button in the plugin settings. ### What are the requirements? WordPress 6.0+, WooCommerce 8.0+, PHP 7.4+, a store trading in USD (v1), and a CarbonGuru account on the Plus plan or higher. Single-site installs only — network activation is unsupported. ### How do I activate, deactivate, re-analyze, or remove a product’s footprint? Per product, right in your store: hover any product in the WooCommerce Products list for **CarbonGuru: Activate / Deactivate / Re-analyze / Remove** actions, or use the same buttons in the **CarbonGuru** box on the product edit screen. For many at once, tick products and use the **Bulk actions** menu (activate / deactivate / analyze). The CarbonGuru column shows each product’s live/off state and footprint.( Removing is permanent and starts a 30-day cooldown, so it always asks first — to just hide a product, use Deactivate.) You can also manage everything from your CarbonGuru panel; the plugin remote-controls that state rather than keeping a second copy of it. ### Can I turn it off? Any time. Pause automatic offsetting from your CarbonGuru panel, or deactivate the plugin — deactivation disconnects your store server-side: keys are revoked, no further orders are reported, and no new purchases are made. Orders already charged are still fulfilled (retired carbon cannot be un-retired). ### Are offsets refundable? No. Once carbon is retired it cannot be un-retired, so offset purchases are final. You confirm this explicitly before automatic offsetting is ever turned on. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “CarbonGuru Merchant Offset” is open source software.
