Fershad Irani
Web Sustainability Consultant

Hey, I'm Fershad. I am a web sustainability consultant working with the Green Web Foundation towards a fossil free internet by 2030.

What I do

I work with the Green Web Foundation on open source projects, prototypes, and writing all with the aim to make web sustainability approachable and accessible to more developers. Some key projects I've been involved with include CO2.js, adding carbon emissions into the Firefox Profiler, and Are my third parties green?

Are my third parties green?

I built aremythirdpartiesgreen.com to help give some visibility to the sustainability of third-party requests on the web. Use it to test your own site, and find out if the external resources being used are hosted on green infrastructure.


I write every so often on my blog about topics relating to digital sustainability and performance. I also write notes and other thoughts at https://qt.fershad.com.
