About this Event
Net zero targets are easy to set. Delivering them is the hard part.
The Big Zero Show brings together the energy managers, sustainability leads, procurement teams and decision-makers who are actually doing the work — and gives them a day to share what is working, what isn't, and what they would do differently.
On Tuesday 23 March 2027 we're back in London at the University of Chicago Booth School of Business for a full day of honest, practical sessions. No glossy promises. Just people who have been through it, telling you how it really went.
What to expect
- Two content streams. Pathway to Net Zero covers the lessons from organisations on the journey — the quick wins, the hard lessons, and how to make progress inside complex organisations. Net Zero Index looks at the bigger forces shaping your strategy: energy policy, procurement, green supply and new technology.
- Real case studies. Last year's speakers included sustainability leaders from the NHS, hospitality, retirement housing, rail infrastructure and the energy sector, covering everything from EV charging hubs across London to Scope 3 in a mega project.
- The topics on your desk right now. Scope 3 data, easy wins for net zero, corporate PPAs, batteries and energy buying, greenwashing and credible claims, and the 2027 policy landscape.
- Time to talk. Networking breaks and lunch built around conversations with peers who face the same challenges you do.
