Frequently asked questions

How does a website produce carbon emissions?
Every page view requires energy — servers processing requests, networks transmitting data, and devices rendering content. The electricity powering these systems often comes from fossil fuels. Heavier pages use more energy.
What is a good carbon footprint for a website?
Under 0.5g CO2 per page view is clean. The average website produces about 1.76g per view. Lightweight, well-optimized sites can achieve under 0.2g. The biggest factor is page weight — smaller pages = less energy.
How do I reduce my website's carbon?
Optimize images (WebP, compress), minify code, enable caching, use a CDN, choose green hosting powered by renewable energy, and remove unnecessary third-party scripts. Lighter pages are better for the planet and for users.
Does green hosting make a difference?
Yes. Hosting providers powered by renewable energy (wind, solar, hydro) produce significantly less carbon. Check The Green Web Foundation directory to find certified green hosts. Hetzner, for example, uses 100% renewable energy.
