Is net zero even possible without open data with Gavin Starks

Tech Tomorrow

The UK’s 2025 Data Act marks a turning point in how data is shared and governed. Just as common standards in telecoms and banking unlocked innovation, trusted data could be the key to credible climate action. But with carbon reporting fragmented and confidence in the numbers low, can open data really help us reach net zero?

In this episode of Tech Tomorrow, David Elliman speaks with Gavin Starks, founder of Icebreaker One, about why net zero is impossible without shared, reliable data. They draw lessons from open banking—how standards, governance, and collaboration turned a technical challenge into a multi-billion-pound ecosystem—and ask what it would take to do the same for climate.

They also spotlight Icebreaker One’s project Perseus, which is building the data infrastructure to automate SME sustainability reporting and connect emissions data directly with green finance. By cutting friction for small businesses and giving banks numbers they can trust, Perseus shows how shared data can turn compliance into opportunity.
