The folks at my favorite website performance testing tool, WebPageTest, just introduced Carbon Control, a way to measure your site’s carbon footprint and run no-code experiments to find ways to improve.
One of the big reasons I advocate for simpler, more performant websites is because the web has a huge environmental impact, and improving performance can help reduce it.
The WebPageTest Carbon Control feature provides actual numbers around your site.
It estimates the carbon generate per page visit, and shows how that compares to driving a car or visiting the average website. It also provides a list of best practices (and shows you performed against them).
To try it, head over to WebPageTest.org and paste in the URL for a typical page on your site. Check the Run Carbon Control checkbox, then activate the “Start Test →” button and you’re off to the races!
