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.

BT’s Q3 was robust in financial terms, delivering revenue growth of 3% and EBITDA growth of 1%, both in-line/ahead of analyst expectations.

Strong broadband ARPU and accelerating FTTP performance at Openreach were the highlights, a weakening BT Business and continued Openreach broadband losses were the main concerns.

This year’s guidance should be easily met, next year’s will be trickier given lower price rises due in April, but the long-term plan of a massive cashflow turnaround when the FTTP build ends is still well on-track.

Mobile sector returns are low, particularly for smaller-scale operators, with H3G earning less than its cost of capital. Regulatory initiatives, spectrum auctions and 5G look set to worsen this picture as H3G strives to gain viable scale

Back-book pricing is crucial to the returns of fixed challengers. Regulatory intervention is likely to lead to a waterbed effect in the fixed sector and exacerbate challenges in mobile

New entrant business case in full fibre is limited to de facto monopoly opportunities. There is the potential for BT’s returns to increase markedly if it gets full fibre right but new entrants’ inferior economics are unlikely to offer sufficient investor appeal

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.
