CO2 Scanner for Third-Party Resources on Websites
"94% of sites use third-party resources, accounting for 45% of website requests. Ensuring these requests are as small as possible, and hosted on green web hosts would be a huge step towards a more sustainable web.
Are my third parties green? allows users to scan the third-party resources used on a web page. The tool checks for green hosting, effective caching, and presents information about transfer size and estimated CO2 produced per download."
