Politics & Society

The German government recognizes that Germany, as a major industrialized nation, bears a special responsibility in climate issues.

The cabinet has therefore presented a 2030 climate protection program to achieve the climate targets. This includes proposals on topics such as energy refurbishment, the expansion of electromobility and price increases for short-haul air travel.

The digital user behavior of our time leads to enormous amounts of data that require enormous amounts of energy. For example, Facebook alone emits as much CO2 as 30,000 citizens in the European Union combined, while the global CO₂ footprint of the Internet is comparable to that of air travel.

By 2040, emissions from the ICT* sector could account for 14% of total global emissions.

We have developed an app that can actively improve Germany's climate footprint! Once downloaded, CO₂free allows you to delete old, unimportant or duplicate files such as photos and videos with just one swipe. This saves a massive amount of data and thus conserves resources.

In addition, the app makes it possible to offset the "smartphone climate effects" by having CO₂ certificates set aside directly via the program.

The three core functions of the

CO₂ App


Our app scans the files, photos and videos on your smartphone and shows you at a glance how much greenhouse gas they cause


A lot of data on your smartphone is outdated or obsolete - for example, because the perfect selfie often doesn't succeed on the first try. Our app suggests such photos and videos; you can delete them with just one swipe.


With the app, you can ask us to decommission CO₂ certificates to offset your remaining footprint. You also get a climate protection plus, because the app eats less energy than we compensate for each download.

CO₂free also pays attention to a good carbon footprint!


● offset own emissions (app, website, server, etc.)

● use energy-saving tools as much as possible and are on the windcloudserver

● work together with sustainable service providers

● Regularly publish their own CO₂ balance sheet

● have a seal for the website (climate-neutral website)

● Offer new customers free neutralization of 1kg CO₂ when downloading the app.
