We present a special episode of SmarterMarkets™, bringing you exclusive interviews from the IETA North America Climate Summit 2025.

SmarterMarkets™ returned to the IETA North America Climate Summit to explore the challenges and opportunities defining the next phase of carbon market development.

This year’s conference examined emerging carbon pricing systems worldwide and the “how” and “when” of driving long-term growth — from the growing role of nature- and technology-based removals to the outcomes of the voluntary market’s focus on integrity and how businesses account for carbon.

In partnership with IETA, we spoke with a cross section of delegates about where they see progress, what challenges remain, and the developments they’re watching most closely as markets evolve.

We’ve compiled 10 of those conversations into this Special Episode of SmarterMarkets™. Our guests, in order of appearance, are:
