Copper 2030 - Skarn's Copper Insight Series, Episode 3

Sophie Chung, CEO - Skarn Associates, looks at the questions facing the copper market in Skarn's Copper Insight Series.

What happens when carbon data starts moving faster than the workflows built to interpret it? Last week, we looked at why two verified copper PCFs may still not be comparable. This week, we move to the commercial consequence. When supplier PCFs are produced on different bases, someone has to establish what those numbers actually mean before they can support a comparison. That work can move between commercial teams, procurement and sustainability before a defensible answer reaches the customer. As these requests become more frequent, repeated interpretation becomes a real operational challenge. At LME Week 2026, Skarn will launch a global copper PCF benchmark designed to tackle this exact problem. You can sign up for the launch and get free trial access here

Copper 2030 is our new series exploring how carbon comparability, sourcing and supplier information could shape copper markets over the next five years, and what buyers, producers and traders will need from that information.
