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.
