Diana Rasner

Diana Rasner is Group Lead at CleanTech Group, a research and advisory firm that tracks and analyzes clean technology innovation across global markets. In her role, she focuses on the materials and chemicals sector, examining how critical minerals and specialty chemicals move through complex, often politically charged supply chains to reach the products and industries that depend on them.

On The Grove, the podcast produced by Earth Onward, Rasner joined host as part of an ongoing series exploring CleanTech Group's Global Cleantech 100 report. Her conversation centered on the materials and chemicals section of the report, offering a clear-eyed look at how minerals factor into nearly every physical product in modern life, whether as direct components or as tools used in manufacturing. She addressed the realities of mineral extraction, recycling, and the geopolitical forces shaping access to these resources, including China's significant hold over key parts of the supply chain. Rasner brought the kind of grounded, specific insight that makes a complicated subject accessible, challenging listeners to look at the objects around them and trace the metals and minerals that made them possible.
