Hello World,

When it comes to climate change, the ongoing digitalisation process can be used as an important tool to reduce our greenhouse gas (GHG) emissions.

However, we are not currently taking advantage of the full potential that digitalisation has to offer. On the contrary, our energy consumption due to an increasing number of networks, user devices, and data centres is starting to outweigh the positive outcomes. Changing this tendency is therefore critical to our planet’s sustainability. Here are some important facts to consider:

  • Our digital energy consumption is increasing globally by about 9% per year.

  • The share of GHG emissions attributable to the digital era will reach 4% in 2020 and will likely double to 8% by 2025.4

  • By 2023, Luxembourg will have 6 204 000 devices, including computers, phones, televisions, cars, all connected to networks. This represents more than 9 connected devices per resident (compared to 5 devices in 2018).5

  • In 2018, digital data use in Luxembourg generated between 9-16 tons of CO­2 every hour and is continuously increasing.6


But take heart! Sustainable, digital positive development is still possible.

A stabilisation process of this exponential growth is possible without hindering the positive developments and innovative power of the overall digitalisation process.

Some facts

Websites are responsible for 12-17% of global internet traffic.7

Luxembourg currently has over 100 000 registered websites.8 We can only guess at how many of these websites remain active.

Generally speaking, the average weight of a website has increased of late, from 1.6 Mb in 2014, to 3 Mb in 2017, to over 4 Mb in 2020.9 Images, videos and visuals are the main driving factors for this increase.

However, “lazy” coding and inefficient website programming have a role in this weight increase too (a more thorough study into the development of the Luxembourgish website would be beneficial ; let us know if you’re interested in such a study).

Some good news

Up to 80% of any single website can be optimised to generate less data traffic.
