  • Justin Winters

    Executive Director

    Over the past decade, Justin has shaped the Leonardo DiCaprio Foundation’s strategic direction and initiated and expanded Leonardo's communications channels - successfully leveraging his global platform to influence decision-makers and the public on pressing environmental issues. She played a key role in his designation as a UN Messenger of Peace on Climate Change in 2014 and in the making of the 2016 documentary film, Before the Flood. Justin introduced One Earth at the World Economic Forum summit in Davos in January 2019, with the launch of the OE Climate Model garnering nearly 1 billion impressions, securing coverage and commentary across global media outlets. As part of an effort to forge stronger links between science, environmental campaigning and popular culture, Justin was instrumental in the release of the Global Deal for Nature plan and petition calling for a new pact to safeguard the planet’s biodiversity, and the “Earth” song by Lil Dicky with 20 major musical artists - driving 100 million views on YouTube, over 12 billion earned media impressions and 1 billion social media impressions. A pioneer of a collaborative approach to environmental philanthropy within LDF, Justin has successfully built out the foundation’s grant-making program and overseen awards of over $100 million to more than 200 high-impact projects in 60 countries. She currently serves on the boards of Amazon Frontlines, The Solutions Project, Oceans 5, Shark Conservation Fund, and Global Fishing Watch.
