Description

Try it out for free => https://tastewp.org/plugins/website-carbon-calculator

The internet consumes a lot of electricity. 1021 TWh per year to be precise. To give you some perspective, that’s more than the entire United Kingdom.

From data centers to transmission networks to the billions of connected devices that we hold in our hands, it is all consuming electricity, and in turn producing carbon emissions equal to or greater than the global aviation industry. Yikes!

The WordPress Carbon Calculator empowers website owners to assess and minimize their carbon footprint. Drawing inspiration from the acclaimed Website Carbon Calculator algorithm 2.0 and leveraging The Green Web Foundation’s co2.js, this user-friendly tool allows you to calculate the CO₂ impact and performance of any page on your website directly from your WordPress admin panel.

You can choose to activate it on selected post types and taxonomies, with full support for custom post types and custom taxonomies.

Key Features:

  • Precision Carbon Calculations: Built upon the Website Carbon Calculator algorithm 2.0 and powered by The Green Web Foundation’s co2.js, delivering accurate CO₂ impact calculations with the latest environmental data.
  • Intuitive Interface: Offers a user-friendly interface within your WordPress admin area, simplifying access to environmental and performance data.
  • Front-End Presentation: Displays the computed CO₂ impact or the Google Page Speed Performance score on your website’s front end, engaging and educating your visitors.
  • Data from Google Page Speed: Utilizes Google Page Speed to gather loaded data, providing comprehensive performance metrics for informed decisions.

Roadmap

  • Translations
  • WebPageTest, GTmetrix and Yellow Lab Tools support
  • Ecoindex.fr algorithm support

Frequently Asked Questions

How does the plugin calculate the CO₂ impact?

The plugin uses the Website Carbon Calculator algorithm 2.0 and The Green Web Foundation’s co2.js to provide accurate CO₂ impact calculations based on the latest environmental data.

Can I display the CO₂ impact on my website’s front end?

Yes, the plugin allows you to showcase the computed CO₂ impact prominently on your website’s front end to engage and educate your visitors.

You can use the following PHP snippet on any page to display the CO₂ impact:

<?php if($calculated_carbon = get_calculated_carbon() ): ?>
This page emits <?=round($calculated_carbon,2)?>g eq. CO₂
<?php endif; ?>

This will output the calculated CO₂ emissions in grams.
