Since the original post, published 17 April 2025, I’ve received feedback from carbon industry participants on the possibility of a global-level benchmark price. Put simply, this feedback endorsed key points in the original post – that, for the reasons set out in the post, there does not exist a credible global-level benchmark carbon price. Moreover, to remedy this situation, industry participants raised the concept of co-creation – that the stronger the signal from the public sector on the benefits and use cases of such a benchmark, the greater the likelihood that the private sector could provide and administer it. Go to the end to continue reading.

In this post, I argue that, to strengthen climate risk metrics, the pricing of carbon should be transparent and consistent. I suggest that lessons can be learned from existing commodities and interest rate markets in the role a benchmark price (for carbon) could play to provide that transparency and consistency. Further, I propose that a benchmark incorporating existing explicit and implicit carbon prices could be sufficiently credible to allow widespread adoption. I then propose a high-level methodology for such a benchmark.
