Videos are one of the largest assets that can be loaded on a webpage, and as such are one of the largest contributors to slow performance and high carbon emissions.
In fact, adding a Youtube embed to a page using the latest default WordPress theme, increased the page transfer size from 21 kb to 973 kb, and loaded an additional 27 resources. That’s an increase in transfer size of 4533%. Adding a Vimeo video increased the transfer from 21 kb to 276 kb, an increase in transfer size of 1214%, and loaded an additional 7 resources.
The Lazy Embed plugin defers the loading of any resource required for playing the video until the video is requested to be played. It does this by adding a srcdoc attribute to the iframe which shows in place of the normal iframe content.
Currently the following third parties are supported
<ul>
<li>Youtube</li>
<li>Vimeo</li>
<li>Dailymotion</li>
</ul>

Lazy Embed

Improves the performance and reduces the emissions of your website by only loading embeds (youtube, vimeo, etc) when they are clicked.

🌍 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>
</ul>
🔒 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.
