Financing biodiversity: Lisa Miller on investing in nature

February 9, 2026 - 07:07

Lisa Miller's path to becoming a leading voice in biodiversity finance began not with spreadsheets or climate models, but with a deep, childhood connection to animals. Growing up in Australia, she felt a fundamental draw to wildlife that existed long before she understood formal conservation arguments. By age six, she already envisioned a future working with them.

Her professional journey, however, took an initial turn into the world of finance. For years, Miller worked in traditional investment roles, gaining a robust understanding of global capital markets. It was this unique combination of innate passion for nature and hard-nosed financial expertise that ultimately led her to a critical realization: the immense economic value of the natural world was systematically absent from the world's balance sheets.

Miller now champions the urgent need to bridge this gap. She argues that protecting and restoring ecosystems—from forests and wetlands to coral reefs—is not just an ecological imperative but a sound financial strategy. The emerging field of biodiversity finance seeks to direct investment toward projects that generate a measurable, positive impact on nature, while also offering returns.

Her work focuses on creating viable financial models and instruments that allow institutional investors and corporations to contribute to nature-positive outcomes. Miller emphasizes that this is not philanthropy, but a necessary evolution of the global economic system to account for the natural capital upon which all prosperity ultimately depends. By translating her lifelong reverence for wildlife into the language of finance, she is helping to build the frameworks for investing in our planet's future.
