The telecoms industry needs to think differently about climate resilience

The telecoms industry has seen significant advancements in recent years, with infrastructure transforming significantly. However, the climate has changed dramatically as well. In 2026, the UK experienced its hottest summer on record, encountering heatwaves, droughts, wildfires, and flash-flood warnings in just the first nine months.

Climate projections indicate such conditions will become increasingly common. This shift necessitates a different approach to resilience, focusing on service continuity rather than individual networks. Telecom operators are already taking steps, such as implementing backup power and cooling, flood protection, and longer-term climate risk planning.

Yet, resilience must be considered within the broader context of the UK's digital infrastructure system. The Telecommunications Security Act has already prompted a more systemic approach to risk identification and disruption preparation. However, climate risks must be addressed with the same operational discipline. Operators' networks are interconnected with other critical infrastructure, such as transport, highlighting the need for systemic resilience.

Extreme weather can strain both telecoms and transportation systems, demonstrating the interconnectedness of dependencies. Collaboration with government, regulators, and other infrastructure industries is crucial. Adaptation must be treated as a strategic national issue, influencing today's infrastructure decisions. Decisions regarding capital investment, network planning, and executive governance must incorporate climate considerations.

Predicting exact future weather conditions is challenging, but we can make informed choices today that remain viable under various future scenarios. Climate risk should be integrated into decision-making language, recognizing its connection to resilience, reliability, efficiency, and investment. Many climate adaptation actions can simultaneously improve efficiency and reduce exposure to energy costs.

Rather than treating climate change, adaptation, and resilience as separate priorities, we should consider how the same infrastructure decisions can address all three. Investing in long-lived infrastructure should prioritize climate resilience, as it is a shared challenge across sectors. Collaborative efforts, including common climate scenarios, cross-sector stress testing, agreed restoration priorities, and clearer protocols, can enhance resilience across industries.
