What is the website carbon assessment?

A website carbon assessment, often facilitated by a website carbon calculator, involves evaluating and estimating the environmental impact of a website in terms of carbon emissions. This assessment takes into account various factors associated with the operation of the website, including the energy consumption of servers, data centers, and the overall infrastructure that supports the site. The goal is to quantify the amount of carbon dioxide (CO2) emissions associated with the website's activities.

By assessing these factors, website owners can gain insights into the environmental impact of their online presence. This information is valuable for making informed decisions on how to reduce the carbon footprint, adopt sustainable practices, and contribute to a more environmentally friendly digital ecosystem. It aligns with the broader goal of promoting sustainability in the tech industry and addressing the environmental challenges associated with internet-related activities. The simple numbers are shown below to clarify how important it is to make a move today.
