Adrian Grenier is an actor, filmmaker, and environmental activist whose work sits at the intersection of storytelling and systemic change. Best known internationally for his portrayal of Vincent Chase in HBO’s Entourage and his role in Netflix’s Clickbait, Grenier has spent the past two decades building a parallel career as one of Hollywood’s most credible and committed sustainability advocates. His message is grounded not in celebrity posturing but in direct action: founding organizations, running campaigns, and living the principles he speaks about on a regenerative ranch outside Austin, Texas.
Sustainability speaker Adrian Grenier co-founded the Lonely Whale Foundation to inspire empathy toward marine species and build a generation of ocean advocates. The foundation’s #StopSucking campaign, targeting single-use plastic straws, became one of the most widely recognized behavior-change campaigns in environmental advocacy, helping shift public and corporate attitudes at scale. In 2017, he helped the UN Environment Programme launch the Clean Seas campaign to end marine plastic pollution. That work led to his appointment as a UN Environment Goodwill Ambassador, a role in which he continues to advocate for ocean health and wildlife conservation through the Wild for Life campaign.
Grenier’s activism has consistently moved beyond awareness. He co-founded Lonely Whale, a nonprofit that pioneered the use of innovation, science, and storytelling to drive ocean advocacy at a corporate and policy level. He also co-founded Earth Speed Media, a sustainability-focused content and strategy firm producing short and medium-form documentary content designed to shift culture around environmental stewardship. Most recently, he served as Chief Earth Advocate for World View, a stratospheric ballooning company, helping develop sustainability strategy and environmental programming for its space tourism experience. In 2020, he founded Kintsugi Ranch, a regenerative farm that he describes as his most direct expression of what sustainable living actually requires in practice.
As a sustainability speaker, Adrian Grenier brings a perspective that few others can offer: the reach of a global entertainment figure combined with the hands-on experience of someone who has built, funded, and run environmental organizations for over a decade. His keynotes challenge audiences to move past intention toward committed, accountable action, and to find the version of sustainability that is honest about trade-offs rather than comfortable with slogans. He is a particularly resonant voice for brands, organizations, and leadership teams navigating the gap between stated environmental values and the structural changes required to honor them.
Most organizations know they need to act on sustainability. Far fewer know how to make that commitment structural rather than symbolic. Drawing from his experience building environmental campaigns that changed corporate policy and founding organizations that operate at the intersection of science, storytelling, and advocacy, Grenier offers a clear-eyed framework for moving sustainability from the communications deck into the operating model. Practical, honest, and free of greenwashing.
The most powerful environmental campaigns of the past decade were not driven by data alone: they were driven by stories that made people feel the stakes. As a filmmaker, documentary producer, and co-founder of Earth Speed Media, Grenier has spent his career studying how narrative shapes behavior at scale. This keynote explores the principles of impact storytelling and gives leaders the tools to use authentic narrative to drive change inside their organizations and with their audiences.
Grenier's journey from Hollywood to a regenerative ranch in Texas is not a rejection of modern life but a recalibration of it. In this personal and candid keynote, he explores what it actually means to align values with daily choices, why the pursuit of sustainability requires honesty about trade-offs, and how individuals and organizations can find a version of conscious living that is honest rather than performative. Particularly resonant for audiences in consumer, lifestyle, and brand-facing industries.
Plastic pollution, acidification, overfishing: the threats to ocean health are systemic and accelerating. Grenier has been on the front line of ocean advocacy for over a decade, from founding Lonely Whale to supporting the UN's Clean Seas initiative. In this keynote he outlines the state of the oceans, the campaigns and innovations that are producing measurable results, and what businesses and individuals can do to become genuine contributors to ocean health rather than bystanders to its decline.
