About Website Carbon Calculator

The Website Carbon Calculator helps you understand the environmental impact of websites. The internet consumes a significant amount of electricity - more than 416.2TWh per year, which exceeds the entire electricity consumption of the United Kingdom.

From data centers to transmission networks to end-user devices, all components of internet infrastructure consume electricity and produce carbon emissions.

How it works

This tool calculates the carbon emissions of a webpage in two ways:

  • URL Analysis: Enter a website URL to have the tool analyze the page and calculate its carbon footprint in real-time.
  • Manual Calculation: If you know the page size (in bytes) and whether it uses green hosting, you can calculate the carbon footprint directly.

The calculation takes into account:

  • The data transfer size of the page
  • Whether the site is powered by renewable energy
  • Adjustments for returning visitors (cached content)
  • Energy intensity of data transfer
  • Carbon intensity of electricity generation

Use this tool to identify opportunities for making your websites more environmentally friendly by reducing page size, optimizing performance, and considering green hosting solutions.
