In this Climate Chat episode, host Dan Miller interviews the CEO of Reflective, Dakota Gruener, about her organization's support of Sunlight Reflection Methods (SRM, a.k.a., solar-geoengineering) research.
Dakota Gruener leads Reflective, a non-profit climate initiative accelerating the pace of sunlight reflection research. Across a career spanning global health, digital privacy, and climate, Dakota has focused on developing frontier technologies with the potential for worldwide impact—while ensuring the risks they pose are addressed responsibly. Originally trained in biology and political science, she served as aide-de-camp to the CEO of Gavi, the Vaccine Alliance, where she supported negotiations with vaccine manufacturers and helped raise $10B to fund five years of vaccine programs in low- and middle-income countries. She was also founding Executive Director of ID2020, a global alliance committed to ethical, privacy-protecting digital identity and served as co-chair of both the WHO Smart Vaccine Certificate Working Group, which set international standards for COVID vaccination certificates, and the Good Health Pass Collaborative, a private-sector initiative (125+ companies) focused on resumption of international travel. Dakota holds a degree from Brown University and is a proud Californian.
