## Summary

Nat Bullard, co-founder of Halcyon and former BloombergNEF executive, joins host Shayle Kann to analyze key trends from his 2025 annual energy slide deck. They discuss how reduced marine and industrial aerosol emissions have inadvertently accelerated global warming by removing a cooling effect, and examine the US's status as the world's largest net energy exporter alongside China's potential peak in oil demand. The conversation also covers the divergence between stagnant ESG rhetoric and actual asset growth, and identifies an oversupply of carbon removal startups relative to voluntary credit issuance.
