🌍 GreenAudit is a technical sustainability toolkit for WordPress — empowering developers, agencies, and eco-conscious site owners to quantify and lower their digital carbon emissions.

Unlike generic carbon calculators, GreenAudit integrates real-time metrics (page weight, energy efficiency, hosting type) with authoritative data from the Website Carbon Calculator API, then generates professional, downloadable PDF audit reports — ideal for compliance, client deliverables, and ESG reporting.

✅ Key Features
– 🔍 One-click carbon footprint analysis per page/post
– 📊 Detailed metrics: CO₂ per page view, energy rating, data transfer
– 📄 Automated PDF reports (using dompdf) — branded, printable, shareable
– ⚙️ Admin dashboard with site-wide sustainability score
– 🌱 Actionable recommendations to reduce impact (e.g., image optimization, caching)
– 🌐 Multilingual-ready (POT included)

💡 Why It Matters
The internet produces ~1.6 billion tonnes of CO₂ yearly — more than most countries. GreenAudit makes sustainability measurable and actionable — aligning with global climate goals and ethical web development.

Built for transparency, security, and scalability — no external tracking, no data collection.

Privacy Policy

GreenAudit does not collect, store, or transmit any personal data by default.

If enabled by the site administrator, the plugin may perform external HTTP requests to public APIs
(e.g., for performance metrics or carbon footprint estimation). These requests may include the
audited URL and basic metadata (e.g., page size, load time), but no personally identifiable
information (PII) or user-tracking data is collected or shared.

The plugin does not set cookies, does not track users across sites, and does not integrate with
third-party analytics or advertising services.

All audit reports (including PDF exports) are generated and stored locally on the site unless
explicitly exported by the administrator.

External Services

This plugin connects to external APIs to analyze website sustainability metrics. These services are required for carbon footprint calculation and green hosting verification.

The Green Web Foundation API

Purpose: Verifies whether a website is hosted on infrastructure powered by renewable energy.
Data Sent: The domain name or URL being audited (e.g., example.com).
When Sent: Each time a user runs a sustainability audit or checks green hosting status.
Service Provider: The Green Web Foundation (non-profit)
Terms of Service: https://www.thegreenwebfoundation.org/about/
Privacy Policy: https://www.thegreenwebfoundation.org/privacy-statement/

Website Carbon API

Purpose: Estimates CO₂ emissions, energy consumption, and environmental impact of web pages.
Data Sent: The public URL being analyzed and basic page metrics (e.g., page size in bytes).
When Sent: Each time a carbon calculation is performed via the plugin dashboard or report generation.
Service Provider: Wholegrain Digital / Website Carbon
Terms of Service: https://www.websitecarbon.com/terms/
Privacy Policy: https://www.websitecarbon.com/privacy/

🔒 Important Notes:
– No personal data, user information, or PII is ever transmitted to these services.
– Only the public URL/domain being audited is sent — identical to what any visitor or crawler would see.
– All API calls are made server-side from your WordPress installation; end-users’ browsers do not connect directly to these services.
– If external connectivity is blocked, the plugin will display a clear error message and skip the external analysis step.
