...and overflowing data streams
Streaming services and, in particular, applications such as videos and games, now account for the majority of energy consumption. In one second, 80,000 YouTube videos are watched, and every minute, 400 hours of additional video footage is uploaded to YouTube
. The hours spent watching Netflix have also risen sharply – from 266,000 to 694,000 hours per minute. It is estimated that streaming services account for 80 percent of the volume of data on the internet, of which one third is adult content.
With the Internet of Things (IoT), all manner of devices, from refrigerators to printing presses are being connected that will constantly exchange information – and this is also reflected in the energy balance. According to a study conducted by Gartner, the number of globally interconnected devices will quadruple from almost 5 billion (as at 2015) to 20 billion in 2020. Cisco, global market leader in IT and networking, is even speaking of a tenfold increase. They all form the pillars for Industry 4.0, whose implementation is also on the agenda in the printing industry.
The treasure diggers of the internet
The trend towards accessing IT resources from the cloud naturally also entails increased energy consumption. Today, data is no longer stored and processed on one's own computer, but in central data centers. As a result, the volume of data transported online has increased enormously. Online shopping, of course, also has its impact and the energy-intensive mining for cryptocurrencies further increases demand for electricity.
The Shift Project
predicts that CO2 emissions from ICT will rise to 8 percent by 2025, which will correspond to the current CO2 emissions of all vehicles. An interesting video
about it. It shows that a single click is negligible, but in total, it nevertheless has an impact.
Printing and paper industry: Putting figures in perspective
And what do all these figures have to do with the printing industry? A comparison with the printing and paper industry shows that ICT has become one of the largest consumers of electricity and that, despite all the ICT industry's efforts toward sustainability, the CO2 footprint is not diminishing. The speculation that digital communication is per se more environmentally friendly than printed communication is untenable. Here, we as the paper and printing industry are called upon to put the figures into perspective.
In North America and Europe, for example, more than 60 percent of the energy used in paper production comes from renewable energy sources. The ICT sector is still a long way from achieving this goal. It goes without saying that paper must also be printed on and transported to the recipient. The rule of thumb here is that 80 percent of the CO2 footprint of printed matter is accounted for by paper production, the rest by manufacturing and shipping.
As a result of progressive process optimization and declining paper consumption, the industry will sooner or later consume less electricity. In its International Energy Outlook for 2016, the US Energy Agency predicts that the share of energy consumption in the paper industry in OECD countries will fall from 6 to around 4 percent in the industrial sector by 2040 – this corresponds to an industry-related drop of 30 percent.
What happens to 65 million tons of electronic waste?
And then there is also the recycling rate. Here, paper, cardboard and corrugated board are in pole position with over 70 percent – digital waste, in particular, is far behind. According to Eurostat, the collection rate for e-waste in 2016 was just over 40 percent. More recent figures are unfortunately not yet available. It is not always clear what happens with such waste. E-waste is partly exported as hazardous waste and ends up in landfill in developing countries.
It is estimated that less than 16 percent of the 65 million tons of electric waste produced worldwide is recycled. But it is not entirely clear why, because it contains true treasures in the form of precious metals and rare earths that are just waiting to be recycled. Paper, on the other hand, has been going through a well-established recycling system for many years.
The myth is not tenable
When it comes to sustainability, there is no need for paper and printing industry to hide, even though there is still a lot to do in our sector. The fact that paper is made from renewable raw materials also plays into the hands of the industry, especially in the current discussion about the use of plastics. This is precisely why it is so important to inform customers, but also end consumers, about the climate-relevant effects of the various channels.
The figures published by the environmental protection organization Greenpeace
do not give a particularly positive picture of sustainability in the ICT sector. The paper and printing industry currently accounts for 1 percent of global C02 emissions (World Resources Institute), ICT for 10 percent. The myth that digital is by definition more sustainable than print is not tenable.
