Automatically check the sustainability of a website with The Green Web add-on.

With the Green Web add-on, you can see the green (or not so green) status of a website at glance, based on what kind of energy is used to power the servers it runs on. Is the site running on green power? Hurray! Smiley face! Is the site is still running on grey power, from fossil fuels? Boo! You'll see a sad face. Why not ask them to switch? But wait! There's more! If you search with Google, Yahoo, Bing or Ecosia, you'll see which sites in results run on renewable power - green links get smiley faces in the results. Also, if you're on a page with links to external sites, you can see if the external site is hosted on green servers too. Links to green sites have a checked green underline on them. The Green Web Foundation maintains an open database listing which datacentres around the world run on green power. We use this to present this information in this browser extension. Both the platform, and the browser extension are open source, so if want, you can see what's happening under the hood when you use the service. In fact, all the source code for all our projects is published on Github, so you can see how they *all* work. We welcome feature requests and contributions to the project. - You can find more information on Release notes: 2.3.0 | 30 June 2020 - Updated icons with transparency to better fit dark mode. 2.2.0 | 13 June 2020 - Add an ethical filtering option, when you enable this option, on search pages results that normally will get a grey smiley as they run on non-green infrastructure will now be filtered out from the webpage, so they are hidden from view.

There's no information on the criteria on which it draws its conclusion. Read Nichol Brummer's review, I completely agree with it. We don't know if it's even neutral or something, google and facebook green but not ecosia search? Right... Also, you only have "green" sites, but no way of knowing if a certain site is gray because they have no data on it or because it's actually "not green". Meh. No way of knowing if this thing is accurate.

If you want to have a green smiley, your host must be registered in their own database:

Try to only use the websites that are hosted green. I had the idea to make such an extension myself but discovered it already existed! I've also done a bit research on what websites are hosted green but I don't understand why for example Facebook is hosted green. Yes, they're building all their new servers with renewable energy but seeing online they will be fully renewable around 2021 which is awesome. Does this extension look to what servers it's connected to see if that specific server is ... Show more
