Frequently Asked Questions

How is website carbon footprint calculated?

We calculate carbon emissions based on the data transfer size, server energy efficiency, and grid carbon intensity. The formula considers the energy needed to transmit data across the internet and serve your page from data centers.

What's a good carbon score for my website?

A clean website typically emits less than 0.5g CO₂ per page view. Anything under 1g is considered good, while 2g+ indicates significant room for improvement. The average web page produces approximately 1.76g CO₂ per page view.

How accurate is the carbon calculation?

Our calculator provides an estimate based on established methodologies. While no carbon calculation is 100% precise, our model follows industry standards and provides a reliable benchmark for comparison and improvement tracking.

How can I reduce my website's carbon footprint?

The most effective ways include optimizing images, removing unnecessary scripts, using efficient coding practices, implementing caching strategies, and choosing green hosting providers. Our tool provides specific recommendations based on your website's analysis.

Does green hosting make a significant difference?

Yes! Hosting on servers powered by renewable energy can reduce your website's carbon footprint by 30-50%. Our tool can identify if your site is using green hosting or provide recommendations for green hosting providers.
