Frequently Asked Questions
How do websites generate carbon emissions?
Every page view requires data transfer and server processing, which consumes electricity. Data centers, network infrastructure, and end-user devices all contribute. The average web page produces about 0.5g CO2 per view.
How can I reduce my website's carbon footprint?
Optimize images (WebP/AVIF), enable compression, minimize JavaScript, use efficient caching, choose green hosting providers, reduce third-party scripts, and implement lazy loading for offscreen content.
Does page size affect carbon emissions?
Yes, directly. Smaller pages transfer less data, consuming less energy at every step. A 1MB page produces roughly twice the emissions of a 500KB page. Image optimization alone can cut emissions by 50% or more.
