5G is a technology that is more energy efficient than 4G, 3G and 2G - it allows us to transfer more data for the same amount of power consumption, and therefore allows us to meet our customers' demands in a more environmentally friendly way. Moreover, Proximus already ensures that 100% of our electricity supply comes from green energy, such as solar panels and wind turbines. So, there are no additional CO2 emissions as a result of the launch of 5G, on the contrary.
