Smartphones? The most polluting devices by 2020

This is what emerges from a study conducted by the Canadian University McMaster, in particular by two professors who analyzed the production chain capable of bringing a mobile phone from the production phase to the palm of our hand.

"For every text message, every call, every video has a data center that consumes a lot of energy and continues to be powered by electricity generated from fossil fuels," explains Lotfi Belkhir, author of the study. "The technological industry - he says - will be responsible for 14% of the total greenhouse gases by 2040 ".

This problem is faced by technology companies like Google and Facebook, which are working to create data centers based on alternative energy. However, the major commitment is undoubtedly that of Apple, which over the years has led its data centers to be powered with 100% renewable energy, receiving praise from many environmental associations, such as Greenpeace.

All this, however, is still not enough.

Also according to the study by two Canadian professors, the greenhouse gases produced by smartphones come from the production cycle.

A source of pollution is represented by the process of extracting the rare metals used to make the internal chips and motherboards. Furthermore, the limited battery life and favorable rate plans push users to change models more often and generate a significant amount of technological waste. This is why - the two professors specify - "by 2020 the energy consumption of a smartphone will be higher than that of PCs and laptops".
