Reconciling 5G and sustainability in Brussels
A sensible policy for a regional government
by Miguel Coma
Brussels' regional government is currently revising its radiofrequency radiation exposure limits. This is a pivotal moment, inspired by corporate desires to deploy 5G, the fifth generation of mobile access networks. I propose that we take it as an opportunity to exercise due diligence on 5G's environmental impactsand to challenge our ministers to enact regulations that reduce them.
Against the grain of ecological impacts
While our government has committed to reducing greenhouse gas (GHG) emissions by 5% per year, the digital sector1,2 already produces much more than pre-Covid civil aviation3. Worse, the digital industry increases its emissions by 6% per year.4 Due to exponential increases in data traffic5, this trend will likely continue to accelerate. To compensate for telecom corporations' increases in GHG emissions, other more essential sectors will have to redouble their effortsand their results.
Manufacturing devices and telecom infrastructure require extractions, energy use, water useand generate greenhouse gases and toxic waste. Manufacturing pollutes soil, water and air. It jeopardizes local populations' health6. Tension over mining fuels armed conflicts, particularly in the Democratic Republic of Congo, where mining already is responsible for more murders than any single event since World War II.7
Deployment without an economic foundation
Compared to 4G, 5G can transfer the same amount of data with less energy. However, 5G's high speed encourages increased usage, especially video, which already accounts for 69% of usage5. Ultimately, this results in much higher energy consumption, the famous "rebound effect". Analysts8 and operators9 agree that with 5G, mobile operators' energy use will multiply two to three times by 2025.
Without proof, telecom corporations claim that 5G could enable energy savings in other sectors. In any case, saving energy does not depend on deploying an additional generation of mobile infrastructure.10
To save energy, let's limit deployment of 5G to private, industrial sites11,12,13 and prohibit its deployment in public spaces. Small businesses and consumers are already largely satisfied with 4G. Its possible saturation could be avoided through various levers14. While some telecoms call 5G a springboard to get us out from our current economic crisis, Bouygues Telecom's CEO considers this claim unfounded.15 A gap is therefore widening between some corporation's techno dreams and economic reality.
5G and health
Regarding antennas' electromagnetic radiation (EMR) exposure limits, the Ghent University and Interuniversity Microelectronics Centre (IMEC) 16 recently looked at exposure to 5G emissions during intensive use. Measurements of Switzerland's first large-scale 5G network reveal values compatible with the current Brussels limits of six volts per meter (V/m) 17even when all 5G antennas transmit at full power. This paper demonstrates that industry claims that 5G deployments require higher limits are incorrect.
Further, no environmental agency has assessed 5G's health riskseven though the World Health Organization categorizes mobile networks' EMR emissions as "possibly carcinogenic;"18 and thousands of studies demonstrate links between EMR exposure and autism, cancer, wildlife harm and much, much more. By increasing "electrosmog," 5G will also further impair the 5% of the population19,20 that suffers from electro-hypersensitivity. An increased screen-time may also increase myopia, addiction and anxiety.
Solutions for 5G compatible with the challenges of our century
In this era of both health crises and massive decline in biodiversity21, governments must prioritize limiting EMR exposure risks to living creatures. Switzerland's strict standards have paved the way for it to deploy 5G under more environmentally and health-friendly conditions. Brussels could enact similar conditionsÃŒ ¶ ÃŒ ¶ while maintaining sound economics.
In light of 5G's exposure levels and the sober objectives that the changing climate imposes on us, governments could therefore:
