According to Website Carbon, a British CO2 analysis service, each webpage visit causes a CO2 emission of an average of 0.8g. That doesn’t seem like much, but the scale makes it significant.

Because: If all 8 billion people in the world visit a page, it causes a CO2 emission of 6400 tons. That’s equivalent to about 3200 intercontinental flights (round trips) over 8000km in economy class.

Assuming a tree binds about 20kg of CO2 per year on average, it would take 320,000 trees to bind the CO2 emission of a single global page visit. One must not forget that everything is released again when the trees die and rot.

All for a single page, which one might not even know whether it will just be clicked away.

We reduce the CO2 footprint in knowledge communication

We combine various methods to reduce the CO2 emission of a page visit. Obviously with success. Website Carbon finds that websites created with a solution rarely generate more than an initial emission of 0.08g. Compared to the average 0.8g, that’s a reduction of 90 percent.

Our recipe:

Lazy Loading

The most effective strategy of all: loading the contents of a page only when they appear in the visible area of the browser. This technique is old and goes by the lovely name of Lazy Loading. It was originally developed for websites with many images or videos, to speed up page loading. We apply it consistently to all contents of a website. The effect is enormous.

No Database

Most solutions for creating websites, such as WordPress, Joomla, or TYPO3, operate with a database. This means a page visit requires resource-intensive interaction with the database, which consumes additional energy and causes corresponding CO2 emissions. Modern methods no longer rely on a database to create websites. We have long freed ourselves from databases, which brings many advantages. For instance, much better interoperability with Artificial Intelligence. But also much better energy efficiency. And lower CO2 emissions.

Standards-compliant websites, lean and error-free

Errors also need to be processed. The careless use of templates and plugins quickly leads to bloated and faulty code. It cannot be processed efficiently and causes increased CO2 emissions with every page visit. Lean and standards-compliant websites can be accessed quickly and with low emissions.


The consistent modularisation of all web resources, such as CSS or JavaScript resources for the design and programming of a website, makes it possible to use them only when they are really needed. This also applies to fonts. They cause surprisingly high CO2 emissions. If the resources are not needed, they are not loaded and therefore do not cause any CO2 emissions.

We combine these and other methods and have integrated them everywhere by default. So you don't have to worry about anything. And you can do something good without having to do anything.
