Rob Greenfield is an adventurer, environmental activist, humanitarian, and dude making a difference. He is dedicated to leading the way to a more sustainable and just world.
Rob is the creator of The Food Waste Fiasco, a campaign that strives to end food waste and hunger in the U.S. He has dove into more than two thousand dumpsters across America to demonstrate how nearly half of all food in the U.S. is wasted while 50 million (1 in 7) Americans are food insecure.
Rob has cycled across the U.S. twice on a bamboo bicycle bringing his message of sustainability and earth-friendly living to America. His first bike ride across the U.S. is now a book, Dude Making a Difference. In 2015 he lived off the grid in a 50-square-foot tiny home in San Diego before auctioning it and raising enough money to build 10 tiny houses for people with no homes.
In 2016 Rob landed in Rio, Brazil without a penny in his pocket on a mission to travel to Panama, 7,000 miles and 7 countries away, relying on the goodness of humanity. This adventure is a six-episode series called Free Ride on Discovery Channel and is playing worldwide. He donates 100% of his media income to grassroots nonprofits. Rob is currently traveling the USA in the service of others and owns just 111 possessions.
Rob’s adventures and his life have caught the attention of the world and he has been featured on thousands of media outlets including the BBC, CBS This Morning, Discovery Channel, USA Today, LA Times, The Guardian, Huffington Post, and TEDx.

Rob Greenfield embodies the essence of sustainability: adaptation and collaboration. As a guest speaker, Rob brings an enthusiasm, knowledge, experience, and playfulness which borders on nonexistent in the world of conservation. He speaks from a purely experiential standpoint and does so by connecting to crowds on an interpersonal level. Despite having accomplished great and notable feats, Rob is able to develop a sense of connectivity with each and every audience member, despite their background or interests, due to his light-hearted nature and positive approach.

-Jonathan Zaidman, Executive Director, The 1:1 Movement


Rob Greenfield was a captivating and passionate speaker who highlighted our sustainability conference. His dedication to positivity and sustainability was strongly apparent, making his presentation as equal in popularity to our national best-selling keynote speaker! It was clear that during Rob’s presentation, a wave of inspiration and excitement spread through the audience, sparking a meaningful discussion about simple living.

-Aaron Hussmann, Former Campus Organizer for CALPIRG Energy Service Corps


I have found that students often feel overwhelmed by the magnitude and scope of global environmental problems, and they sometimes feel helpless in reflecting on their roles in potential solutions. Rob was able to connect with the students in a practical and engaging way, and he appealed to their interests in a manner that academic texts are unable to achieve. Furthermore, his experiences provided the basis for our ongoing class discussions about the various ways that each of us can communicate about our environmental attitudes and concerns, and about suggestions for new approaches, behaviors, or habits. In a word, Rob’s discussion with this class was inspirational, and the enthusiastic responses from the students confirmed its value for their learning experiences.

Rob Greenfield gives us the gold standard in sustainability presentations. He rivets his audiences with stories of his unique adventures and incredible visuals. Rob shows us that living sustainably just requires some thought, preparation and sometimes a little bit of grit. All of us need to live more sustainably and Rob shows us how. He shows us that going to the extremes of sustainability is doable, satisfying, educational and fun.

-Dave Engel, co-founder San Diego 350 Planet Based Diet Team


I highly recommend inviting Rob Greenfield to speak to your class or group about sustainable living and making a difference. Rob spoke to my sustainability and justice class in San Diego City College’s Peace Studies program, and the students loved it. He’s a very engaging speaker and the students found his story to be accessible, relatable and inspiring. Rob shows that someone just like them can make a big difference just by making some changes to how they live their lives. He makes this seem not only feasible, but fun!

-Stephanie Knox Cubbon, Peace Studies Professor, San Diego City College


Rob came to a chilly Lancing College on the south coast of England, to talk to our 16 and 17 year olds and truly inspired them with his passion for the environment and how to live lightly on the earth. We have so many plans to improve the school’s approach to the environment as a result of Rob’s visit. He was great fun and his sheer zest for life was infectious.

-Daniel Connolly, Assistant Head, Lancing College


The impact of his story was evident in the fact that people came from right across London and beyond to hear him speak about zero waste living and his invaluable observations. Rob is a doer, plain and simple and because of that he is a change-maker and inspiration to us all. This is what matters, his hands on approach to getting things done will be the thing that makes the difference.

-Alice Gilsenan, Co Founder Tiny Leaf London


Rob was very eloquent and was able to connect deeply with students. Students have since taken his advice on how to reduce waste on campus by advocating for on-campus markets to donate
their food to the Triton food pantry and occasionally dumpster diving.I really appreciate and admire the passion that Rob has for protecting the environment, and I feel like he made a lasting impact on the students’ perception of food waste and policy.


-Katharine Moses, Project Director of Consumer Waste Reduction at UC San Diego

We knew an event photo of a fit dude naked on a bike might draw in a few more audience members than our events usually do, what we didn’t anticipate was the enormous effect Rob would have on the student body. Never has the society had so many people signing up to actually be involved. He took the ideas of sustainability that everyone had talked about for years in the society and brought them alive. The increase in environmental action on campus is absolutely amazing. Rob has wonderful friendly charisma and a way of making his lifestyle and ways of addressing incredibly important environmental issues  accessible and desirable. People still come up to me 5 month later and tell me what a super few days it was. I think the most telling thing is that no one felt like a message was being forced upon them. Everyone had fun. Everyone wanted to be his friend. What more could you want from an ambassador for good?

-Aine O’Gorman, President of Environmental Society at Trinity College Dublin
