WordPress Carbon Footprint is a simple plugin for WordPress which works out and displays the carbon footprint of your blog. It works out how many words and images are on your blog and then calculates how many sheets of paper it would take to print a copy of your blog. It finally works out how much carbon is in those sheets of paper and displays all this information for you or your readers so you can show off how much carbon you?re offsetting by hosting your content online.
<ul>
<li>The script searches through every post and every page on your blog, counting the total number of words and images in each post.</li>
<li>It then works out how many pages the text would take up assuming a standard of 794 words per page. This was worked out by taking the most widely used fonts, font sizes, the word processor being used and other print options.</li>
<li>It also works out how many pages the images would take up, again based on DPI, margins and other factors.</li>
<li>The most widely used paper is around 120gsm (grams per square meter) and standard A4 paper is 210x297mm. This means that we can approximate that there is 0.0074844g of carbon per sheet of paper which we multiply by our number of pages to give the total amount carbon saved by the blog vs it being printed out on paper.</li>

WordPress Carbon Footprint

🌍 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 <a href="https://www.websitecarbon.com" rel="nofollow ugc">Website Carbon Calculator API</a>, 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.
<h3>Privacy Policy</h3>
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.
<h3>External Services</h3>
This plugin connects to external APIs to analyze website sustainability metrics. These services are required for carbon footprint calculation and green hosting verification.
<h3>The Green Web Foundation API</h3>
<ul>
<li>Purpose: Verifies whether a website is hosted on infrastructure powered by renewable energy.</li>
<li>Data Sent: The domain name or URL being audited (e.g., <code>example.com</code>).</li>
<li>When Sent: Each time a user runs a sustainability audit or checks green hosting status.</li>
<li>Service Provider: The Green Web Foundation (non-profit)</li>
<li>Terms of Service: https://www.thegreenwebfoundation.org/about/</li>
<li>Privacy Policy: https://www.thegreenwebfoundation.org/privacy-statement/</li>
</ul>
<h3>Website Carbon API</h3>
<ul>
<li>Purpose: Estimates CO₂ emissions, energy consumption, and environmental impact of web pages.</li>
<li>Data Sent: The public URL being analyzed and basic page metrics (e.g., page size in bytes).</li>
<li>When Sent: Each time a carbon calculation is performed via the plugin dashboard or report generation.</li>
<li>Service Provider: Wholegrain Digital / Website Carbon</li>
<li>Terms of Service: https://www.websitecarbon.com/terms/</li>
<li>Privacy Policy: https://www.websitecarbon.com/privacy/</li>

🔒 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.
