At the end of winter term in 2014, Lotfi Belkhir was approached by a student taking his Total Sustainability and Management course who asked, “What does software sustainability mean?”
The Entrepreneurship and Innovation Associate Professor at the W Booth School of Engineering Practice and Technology didn’t have an answer.
Belkhir teaches students to think creatively about sustainability tools that can be applied to their entrepreneurial ventures. But his tools, at the time, mainly applied to hardware startups, not software.
The student’s question sparked Belkhir’s latest research on the global emissions footprint of information and communications technology (ICT).
Belkhir, along with Ahmed Elmeligi, a recent W Booth grad and co-founder of the startup, HiNT (Healthcare Innovation in NeuroTechnology), studied the carbon footprint of consumer devices such as smartphones, laptops, tablets, desktops as well as data centres and communication networks as early as 2005. Their findings were recently published in the 2018 Journal of Cleaner Production.
Not only did they discover that software is driving the consumption of ICT, they also found that ICT has a greater impact on emissions than we thought and most emissions come from production and operation.
“We found that the ICT industry as a whole was growing but it was incremental,” Belkhir explains. “Today it sits at about 1.5%. If trends continue, ICT will account for as much as 14% for the total global footprint by 2040, or about half of the entire transportation sector worldwide.”
“For every text message, for every phone call, every video you upload or download, there’s a data centre making this happen. Telecommunications networks and data centres consume a lot of energy to serve you and most data centres continue to be powered by electricity generated by fossil fuels. It’s the energy consumption we don’t see.”
Among all the devices, trends suggest that by 2020, the most damaging devices to the environment are smartphones. While smartphones consume little energy to operate, 85% of their emissions impact comes from production.
A smartphone’s chip and motherboard require the most amount of energy to produce as they are made up of precious metals that are mined at a high cost.
Smartphones also have a short life which drives further production of new models and an extraordinary amount of waste.
“Anyone can acquire a smartphone, and telecommunications companies make it easy for people to acquire a new one every two years. We found that by 2020 the energy consumption of a smartphone is going to be more than that of PCs and laptops.”
Belkir has made policy recommendations based on his findings.
“Communication and data centres have to go under renewable energy now. The good news is Google and Facebook data centres are going to run on renewable energy. But there needs to be a policy in place so that all data centres follow suit. Also, it’s not sustainable to have a two-year subsidized plan for smartphones.”
With his latest research, Belkhir hopes to help students in his Total Sustainability and Management course expand their worldview.
“When they start the course, many students don’t know what sustainability means. When the course ends their worldview has changed and they realize what they want to do and why they want to do it.”
