After a much-needed Summer break, The Scope 3 Podcast is back, and Ollie and Tom are coming in strong with an episode all about what good looks like when it comes to supply chain sustainability.

As usual, it’s a double-header, with two brilliant conversations that dig into the real dynamics behind buyer-supplier relationships, what it takes to decarbonise, and why so many companies are still stuck at the starting line.

First up, Ollie sits down with Andrew Baer, Head of Sustainable Procurement at S&P Global, and Don Gregori, COO of First Factory, one of S&P’s long-standing tech partners. What unfolds is a genuine, thoughtful conversation about how these two very different companies found common ground and built a relationship rooted in trust, transparency, and mutual progress. Don’s honesty about the early resistance to sustainability requirements, and how First Factory became carbon neutral in under a year, makes this a must-listen for anyone navigating supplier engagement.

Then, Tom takes over for a chat with Simon Geale and Jamie Ganderton from Proxima, the procurement consultancy working at the sharp end of Scope 3. They share what they’re seeing across the market, why most procurement teams still don’t have a real plan, and what needs to change – fast – to move from strategy to action. Drawing on insight from over 300 companies who’ve taken their Scope 3 Maturity Benchmark, they break down what separates the leaders from the laggards, and why embedding carbon into procurement decision-making is no longer optional.

In both conversations, one theme keeps rising to the surface: progress doesn’t happen without people. Real people, having real conversations, asking good questions, and building the kind of relationships that make room for progress – not just pressure.

If you're in procurement, sustainability, or anywhere near a Scope 3 target, this episode is packed with lessons, stories, and a few uncomfortable truths, but also a lot of hope.
