Justin Winters is the Co-founder and Executive Director of One Earth, a nonprofit organization working to galvanize collective action to solve the twin crises of climate change and biodiversity loss through groundbreaking science, inspiring media, and an innovative approach to climate philanthropy.

Through One Earth, she is working to create a world where humanity and nature coexist and thrive together through three pillars of action: a just transition to 100% renewable energy, protection and restoration of 50% of the world’s lands and oceans, and a shift to regenerative, carbon-negative agriculture.

Justin was instrumental in launching Daughters for Earth, a new campaign and fund that aims to mobilize all women to actively engage in climate action by supporting on-the-ground, women-led efforts to protect and restore the Earth.

Prior to One Earth, Justin served as Executive Director of the Leonardo DiCaprio Foundation for 13 years, where she built the organization’s grant-making program, which awarded over $100 million in grants across 60 countries and created a series of innovative philanthropic funds, including Oceans 5, Shark Conservation Fund, The Solutions Project, Lion Recovery Fund, Elephant Crisis Fund, and Quick Response Fund for Nature.

Justin is committed to empowering everyone to become a philanthro-activist for the Earth and supporting impactful, community-driven climate solutions all over the world.
