Monitoring and reducing digital carbon footprint is crucial in our modern world, as more and more companies and organizations realize their responsibility for the environment. Purement, as an accurate website carbon emissions calculator, plays an important role in tracking and calculating website CO2 emissions. In this article, we will explain how Purement performs these calculations and how this helps improve environmental impact.

A key element of how Purement works is the client-side capture of resources loaded on a website. This means that the Purement script, which is integrated into the HTML code of a website, actually captures the resources that are downloaded when a page loads. These can be images, scripts, stylesheets, and other files necessary to render a web page.

The key advantage of this client-side capture is that Purement is able to accurately calculate CO2 emissions for each individual page view. Instead of using rough estimates, this method allows us to determine exactly how much emissions each visit to a website actually generates. This allows companies and website operators to get accurate data on what their digital carbon footprint looks like.

In addition, this method allows an analysis of the resources used when loading a website. Purement can determine which specific resources, such as images, scripts or videos, account for what proportion of the total emissions of a page load. This allows website operators to target and optimize those elements that contribute the most to their emissions. By identifying bottlenecks and optimization opportunities, companies can not only reduce their environmental footprint, but also increase website efficiency and improve load times.

This detailed pageview-level analysis enables precise action to be taken to reduce the carbon footprint and helps make digitization more sustainable.

To calculate CO2 emissions, Purement uses CO2.js, a technology developed by The Green Web Foundation. This innovative tool allows us to more accurately understand and quantify the environmental impact of the web. CO2.js is based on extensive data and models that take into account the energy consumption of servers, data transmission and other factors that contribute to the emission of CO2.

Purement's calculation of CO2 emissions is an important step towards sustainability in the digital sector. By being able to accurately measure the actual impact of the internet on the environment, businesses and website operators are able to take targeted action to reduce their digital carbon footprint. Purement makes it possible to promote environmentally conscious actions and helps to make Internet use more sustainable.
