It is time we start to more comprehensively and actively measure the carbon impact of websites.
There are a number of challenges to calculating this impact but I was very enthusiastic when I saw that WebPageTest introduced a carbon control feature. The team at WebPageTest bring some engineering and design skill to communicating the impact of a websites carbon footprint.
I have tried alternatives, two small independent operators, and I had not optimal experiences with previous carbon measuring platforms. It just felt hard to put weight on the numbers. WebPageTest is an established brand that brings some good experience to the table and I am happy with their methodology so far.
More importantly I am convinced they can only go on to improve and calibrate the carbon control tab with more information. Kudos to Catchpoint/WebPageTest!
