According to one estimate, in 2022 around 5.3 billion people worldwide have access to the Internet [1]. Every single search query, every streamed video and every type of cloud computing, executed billions of times, is responsible for ever-increasing global demand for energy and thus also for increasing CO₂ emissions. The lion's share of the digital footprint is caused by video streaming due to large data sizes of videos. By comparison, using a search engine or sending text-only emails has a negligible impact. In light of constant technological progress, increased efficiency, changing consumer habits and the substitution and summation effects, it is difficult to estimate exactly how large the global CO₂ emissions are. Various studies estimate them to be between 2.3 - 3.7 percent of global CO₂ emissions, which is equivalent to the emissions of the entire aviation industry [2]. On an individual level, it is possible to estimate more precisely how high the CO₂ emissions are and how they can be reduced by simple means.
Simple means to reduce emissions in everyday digital life:

Reduce streaming: Video streaming causes 75 percent of global data traffic [3]. Production of the device (smartphone, laptop, TV), internet network energy consumption, several involved data centres and servers/routers, energy consumption use of device during streaming itself. By comparison downloading is much less energy-intensive.

Play songs as audio files rather than streaming them as a video on YouTube or watch the video at a lower resolution [4].

Use devices longer: The average useful life of a smartphone in Switzerland is just two years, that of a television five years [5].

Dispose of old devices correctly.

Empty your e-mail box regularly to reduce data storage.

Store data locally, use the cloud as little as possible (applies to private individuals, for companies with server structure "on premise" rather vice versa)

Use WLAN networks instead of mobile networks.

Use a renewable energy mix (photovoltaic, hydropower, wind, biomass).
