Direct greenhouse gas emissions from the UK telecoms sector equate to around 0.1-0.3% of the UK total. Most operators have set targets to reach net zero across their direct emissions in the next 10-20 years, with the move to electric vehicles an obvious win.

Network upgrades to 5G and fibre have the potential to cut emissions from electricity by a factor of 10, and consolidation offers further decarbonisation upside.

The industry could enable emissions savings in other sectors equivalent up to 30x its own by averting the need to travel and through IoT applications, with the latter requiring careful commercial assessment given the financial constraints in the industry.

The combination of 5G, AI, IoT and big data were evangelised at MWC as generating massive scope for the transformation of multiple industries. 

That much is probably true, but it is the tech and consultancy companies who will likely receive the benefits, with connectivity revenue likely to be modest.

For the operators, 5G brings more capacity much needed for hungry smartphone users, and perhaps the opportunity to transform themselves into a leaner operating model.
