Investing in the Supply Chain behind Renewables with MUUS

Today, we’re diving into a part of the climate transition that doesn’t get nearly as much attention as solar panels, electric vehicles, or AI: the materials, minerals, and manufacturing systems that make modern civilization possible. Steel alone accounts for roughly 7–8% of global greenhouse gas emissions, and the energy transition is driving unprecedented demand for critical minerals, advanced materials, and domestic manufacturing capacity. These sectors offer incredible investment opportunities, and that’s the focus of my guest, Kavita Patel.
Kavita is a portfolio manager for venture investment for MUUS & Company (MUUS), the family office of TIGER 21 Founder and Chairman, Michael Sonnenfeldt, and his family.
We discuss opportunities ranging from critical mineral recycling to next-generation building materials, what she’s learned investing through the ups and downs of climate tech, and why she believes some of the most compelling opportunities today may be hiding in sectors many investors overlook.
We also explore where climate capital is flowing, where it may be underinvesting, and how investors can think rigorously about both financial returns and real-world climate impact.
I learned a lot from this conversation, and I think you will too. Here we go.
