This episode – our half century – features two very different conversations, but both land on the same core question: how do companies actually make Scope 3 decisions in the real world when cost, speed, suppliers, engineering, data quality, and commercial pressure all collide?

In this episode of the Scope 3 Podcast, Ollie, Tom and Dexter unpack a rapidly shifting landscape – from regulation and standards to the reality of making Scope 3 actually work in practice.

Ollie (broken rib et al), Tom and Dexter open episode 48 with a discussion on new developments from the California Air Resources Board around the Corporate Climate Data Accountability Act.

This episode pulls together two sides of the same story – the people asking for change in supply chains, and the people actually being asked to deliver it.

Fresh from his time on the slopes, Dexter is back with his fellow hosts Ollie and Tom to explore how businesses are moving from measurement to real transformation across their value chains.

This time on the Scope 3 Podcast, it’s just Ollie and Tom (Dexter’s off skiing in style), and we dive into two very different – but equally practical – conversations:

• What real supplier engagement looks like when you stop talking about it and actually do it

• And how soil carbon measurement is evolving beyond theory and pilots into something that could scale globally

This episode was recorded live at the Scope 3 Peer Group Strategy Days in London.

More than 350 peers came together for three days of practical sessions, honest reflection and working groups focused on real delivery. The mood this year was clear: less theory, more action.

In this episode of the Scope 3 Podcast, Ollie, Tom and Dexter take stock of where Scope 3 really is right now – what’s changed, what hasn’t, and why many organisations feel a growing pressure to move from counting emissions to actually cutting them.

Ollie, Tom and Dexter are getting back into the swing of it for the new year – and setting the context for what’s shaping Scope 3 work right now.

This episode has a bit of everything: hard-won progress, honest challenges, and something of a new format.
