On 17th June, the Harvey Nash Newcastle team attended TechNExt, the North East’s flagship technology festival, bringing together thousands of attendees across five days to celebrate the region’s thriving tech scene.

As part of the festival the team took to the TechNExt Sustainability Hub alongside David Savage, Group Technology Evangelist, to showcase the fifth instalment of the Tech Flix docuseries, ‘Data’s Untold Story: The AI Energy Crisis’, a thought-provoking documentary exploring the growing tension between innovation, data and sustainability.

Held in Blyth, the session welcomed attendees with an introduction by Michael Day, Associate Consultant, who set the scene for what is becoming an increasingly urgent issue: the exponential growth of data versus the energy required to sustain it. The documentary was then presented to the audience, which explores the mounting challenge of energy consumption in technology and data and what that means for our digital future.

Following the screening, a panel of industry leaders took to the stage to reflect on the film’s themes and share their own perspectives. The panel featured:

  • Joanne Todd, CIO, St John Ambulance
  • Jayne Routledge, Digital, Data and Technology Director, Everyturn Mental Health
  • Paul Fitton, Director of Digital and Innovation Northern Powergrid
  • Stuart Redshaw, IT Manager, Tombola

Moderated by David Savage, the panel tackled some of the film’s most pressing questions: What is the true cost of storing our ever-growing digital data, and how do we maintain long-term sustainability strategies when the average tenure of a senior leader is just over three years? - as reported in the Nash Squared/Harvey Nash Digital Leadership Report 2025.

Key themes from the discussion included:

  • Return on impact: Rather than focusing solely on traditional ROI, panellists stressed the importance of understanding the broader impact of sustainability projects, both environmentally and socially. Jane Routledge highlighted the challenge of aligning the board with long-term sustainability goals, advocating for a shift in how value is measured and communicated.
  • Leadership turnover and continuity: A recurring theme from both the film and the panel was the issue of leadership churn. With digital leaders often in post for less than four years, the panel questioned how organisations could maintain momentum and accountability for long-term net-zero goals.
  • Shared responsibility in the digital supply chain: The panel also discussed the role of major cloud and tech providers, such as Microsoft and AWS, in the sustainability equation. It's not just about individual business actions; suppliers too must take accountability for the energy their platforms consume.
  • The ethics of AI and data consumption: As AI becomes more integrated into business operations, ethical concerns around its environmental impact surfaced. Questions from the floor explored whether issues like AI governance and energy usage were being properly discussed at board level, the general consensus was that they’re not, but they should be.
  • Should data consumption be taxed? One particularly provocative idea raised by the audience was the introduction of a “gigabyte tax” on data consumption, similar to a carbon tax. While the idea was ultimately deemed unworkable (due to the risk of rising end-user costs), it sparked important dialogue around how governments and regulators might incentivise more sustainable tech practices.

While the session didn’t promise clear-cut answers, what it offered was arguably more important: a space for debate, reflection and collective responsibility. From practical strategies to philosophical challenges, the panel opened new ways of thinking about tech’s role in sustainability.

As Nash Squared/Harvey Nash’s Tech Flix series continues to tour the UK, events like this provide a critical platform to drive forward the conversation - not just about what the problems are, but about who is responsible and how we move forward together.
