About this extension

GreenCheck is a browser extension that identifies websites running on green energy and does analysis on the site’s carbon emissions.

Read the publisher’s full description

🌱 Key Features Instantly spot which websites are powered by green energy with a leaf icon (🌱). See details about the hosting provider and access a dropdown with public documentation on their green energy claims. Uses The Green Web Foundation’s verified dataset, ensuring reliable information on providers that actively reduce, avoid, or offset emissions from electricity use. Already on a website? Open the extension’s popup to check if it’s running on green energy. View the hosting provider, energy status, and supporting information—all in one place. Run a Carbon Analysis to calculate the emissions from reloading a page. Get an easy-to-read rating (A+ to F) comparing its carbon footprint against others. 🌱 About Us GreenCheck was founded in Scotland in June 2024 to make the invisible energy impact of the web easier to understand. Our mission: help people make more informed choices about the websites they visit and the energy sources powering them. We also care deeply about your privacy—your browsing history and personal data remain completely private. 🌱 Changelog July 2024 – v0.1.0: Beta release for early feedback. January 2025 – v0.2.0: New checkbox logo + dependency updates. September 2025 – v0.3.0: Faster performance + removed license key requirement.
