Estimate WooCommerce order emissions and review carbon reports with dashboards, trends, exports, and product insights.

== Description ==

VerdantCart Carbon Reports helps WooCommerce stores estimate carbon emissions from orders and review reporting data over time.

It turns completed WooCommerce orders into period-based carbon reporting snapshots, helping merchants understand trends, identify higher-impact products, and export reports for internal sustainability review.

The plugin calculates estimated emissions for eligible WooCommerce orders, aggregates reporting data by period, and displays results in dashboards for both store-level and customer-level reporting.

Main reporting features include:

* Estimated carbon emissions per WooCommerce order
* Monthly, weekly, and yearly reporting views
* Store-level and customer-level dashboards
* Trend comparison against previous periods
* Product hotspot reporting
* CSV and PDF exports
* Sustainability insights
* Snapshot-based reporting for stable historical results

VerdantCart Carbon Reports is useful for:

* WooCommerce stores that want visibility into estimated order emissions
* Merchants preparing internal sustainability summaries
* Brands monitoring emission trends over time
* Store owners who need exportable reporting data

This plugin provides operational sustainability reporting based on WooCommerce order data. It is not a certified ESG report, GHG Protocol report, legal compliance document, or verified carbon audit.

== Features ==

* Estimate emissions for WooCommerce orders
* View reporting by month, week, and year
* Review store-level reporting data
* Review customer-level reporting data
* Compare reporting periods
* Identify higher-impact products with hotspot reporting
* Use snapshot-based reporting for stable results
* Export reports as CSV or PDF
* View sustainability insights
* Run backfill for historical WooCommerce orders

== Installation ==

1. Upload the plugin folder to the `/wp-content/plugins/` directory, or install the plugin through the WordPress Plugins screen.
2. Activate the plugin through the **Plugins** screen in WordPress.
3. Make sure **WooCommerce** is installed and activated.
4. Open **VerdantCart Carbon Reports** from the WordPress admin menu.
5. Create a completed order or run **Backfill** to generate historical reporting data.

== Usage ==

After activation, open VerdantCart from the WordPress admin menu to view carbon reporting for your WooCommerce store.

The plugin can:

* Estimate emissions for eligible WooCommerce orders
* Aggregate reporting data by month, week, and year
* Display store-wide reporting and customer-facing dashboard data
* Highlight higher-impact products
* Export reports for further use

For stores with existing completed orders, use the Backfill screen once to build historical reporting data.

The customer-facing dashboard can be added to a WordPress page from the plugin setup flow or by using the dashboard shortcode.

== How It Works ==

VerdantCart Carbon Reports estimates emissions using internal calculation rules applied to WooCommerce order data.

Reporting data is stored inside your WordPress installation and organized into aggregated snapshots used by dashboards, comparisons, insights, hotspots, and exports.

The plugin uses snapshot-based reporting so historical reporting periods remain stable instead of being recalculated during normal dashboard page loads.

== Data & Privacy ==

All core calculations are performed locally in your WordPress installation.

The plugin does not require sending WooCommerce order data to an external service for its core reporting features.

== Requirements ==

* WordPress 6.4 or higher
* PHP 8.0 or higher
* WooCommerce 8.0 or higher

== Frequently Asked Questions ==

= Why does my dashboard show "No snapshot available"? =

That reporting period does not yet have generated snapshot data. Create a completed order or run the **Backfill** tool to generate reporting data.

= How are emissions calculated? =

Emissions are estimated using internal calculation rules applied to WooCommerce order data.

= Can I export reports? =

Yes. The plugin supports CSV and print-ready PDF exports.

= Which reporting periods are supported? =

The plugin supports month, week, and year reporting views.

= Does this plugin require WooCommerce? =

Yes. WooCommerce must be installed and active.

= Does the plugin send order data to an external service? =

No. Core reporting calculations are performed locally inside your WordPress installation.

= Is this a certified ESG or carbon audit report? =

No. VerdantCart Carbon Reports provides operational sustainability summaries and estimated emissions reporting. It is not a certified ESG report, GHG Protocol report, legal compliance document, or verified carbon audit.

== Changelog ==

= 1.2.4 =
* New: In-plugin launch announcement for VerdantCart AI Pro v1.4.1 — appears at the top of wp-admin until 2026-07-04, dismissible per user, with one-click access to VerdantCart AI Pro information and the latest Scope 3 emissions guide.
* Hidden automatically for users who already have Pro active (via Freemius detection), so existing Pro customers see no noise.
* No changes to core reporting features — all dashboards, exports, snapshots, and insights continue to work exactly as in v1.2.3.

= 1.2.3 =
* Corrected Pro pricing display in admin upsell cards: now correctly shows $19/month and $179/year (Save 21% — over 2 months free).
* Added support contact: support@verdantcart.ai is now displayed in all upgrade prompts so users can reach the team directly.
* Improved Pro upgrade CTAs across admin: emphasized the 14-day free trial (no credit card required) instead of generic "Upgrade to Pro" buttons.
* Added subtle Pro discovery hint at the top of free plugin admin pages — informational, brand-colored, with one-click dismiss (auto-reappears after 30 days).
* Side-by-side layout on the Advanced sub-menu: "Included in Pro" and "License Management" cards now sit next to each other on wide screens, reducing scroll.
* Refined upsell messaging to clarify trial benefits and reduce friction at the moment of decision.
* No functional changes to core carbon reporting features — all reports, exports, and analytics work as before.

= 1.2.2 =
* Enhanced VerdantCart AI Pro experience and upgrade workflow.
* Added detailed feature descriptions and a Free vs Pro comparison table.
* Improved license management interface and validation experience.

= 1.2.1 =
* Fixed: undefined method `VCARB_Export_Audit::table()` causing a fatal error on CSV and PDF export requests.
* Fixed: trend label "X%lower" / "X%higher" missing a space between the value and the word in CSV exports and PDF exports. Now correctly renders "X% lower" / "X% higher".
* Added: 11 new `apply_filters()` extension points so an external plugin can inject business name, logo URL, brand color, footer note, disclaimer, and per-format export metadata into the Sustainability Summary, PDF report view, and CSV exports without forking.
* Added: optional Pro-rendered brand block (logo + business name + brand color divider) above the Sustainability Summary header when a consumer of `verdantcart_report_logo_url` / `verdantcart_report_business_name` is registered. The page renders unchanged when no consumer is present.
* Improved: removed all remaining legacy `AmatorCarbon`/`amatorcarbon_*` references (admin slugs, helper aliases, filter dispatches, AJAX actions, meta key fallbacks, option fallbacks, uninstall cleanup). Internal prefix is now uniformly `vcarb`/`VCARB_`.
* Improved: simplified `verify_insights_nonce` to a single-action check now that the legacy nonce alias is no longer needed.
