Frequently asked questions about digital footprint and sustainable web

What is the "digital footprint" of a website?
It is the CO₂ emissions and energy consumption derived from loading a page. It is estimated based on the transferred size, the electricity used in transmission/server, and the carbon intensity of the electrical grid. Methodology.
What data does the calculator use?
Results from PageSpeed/Lighthouse and estimates from CO2.js compared with Website Carbon. This is how we prioritize actions with real impact on performance and emissions.
How do I quickly reduce my footprint?
Start with eco-friendly WordPress hosting, maintenance and sustainable web design. You will see improvements in CO₂ per visit and in Core Web Vitals.
