For the first episode of Green I/O, I interviewed Fershad Irani a web performance expert and restless advocate for a low carbon web in his newsletter "Optimized". He helps environmentally conscious companies ensure their websites are fast, optimised for performance, and have a low carbon impact. Based in Taipei after graduating in Sydney, Fershad also contributes to open-source projects like OpenSpaceData and is an active member of the climateaction.tech community, where I discovered his work. He has recently launched 'Are my third parties green?' a much-needed tool to give some visibility to the sustainability of third-party requests on the web.
