About Rob
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 the U.S. 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. three times on a bamboo bicycle, bringing his message of sustainability and earth-friendly living to the nation. His first bike ride across the U.S. is now a book, Dude Making a Difference. On his third cross country ride, Green Riders, he was joined by 48 people throughout the ride, all doing good deeds on bikes.
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 in Paris, France in 2017, giving his second TEDx


To date, Rob has spoken at over 100 events to more than 10,000 people in 11 countries. He has spoken at a wide range of venues from elementary school through universities, small businesses to international corporations, rural villages to big cities, municipal organizations, nonprofits, and more.

He is able to relay his message to people of all ages and walks of life and has connected with 4-year-olds at preschools to elders in senior care centers.

He has given two TEDx talks, present at TEDxTeen on “How to End the Food Waste Fiasco in London” and TEDxIHEParis in Paris on how to “Be the Change in a Messed up World.”

Above all else in his public speaking, Rob is proud of the fact that he’s able to inspire people enough that when they walk out of the room, they commit to making changes for a better world. His talks are not just educational and inspirational but often quite hilarious, making the topic of sustainability much more attainable to a wide range of people. He is able to reach people who’ve barely thought of environmental issues, yet there is no choir for Rob to speak to. Because of his lead-by-example actions and his extreme dedication to the cause, he is able to inspire people who’ve been working in the field for decades to take things a step further.

Book Rob. Book him now. Not only does he have the most compelling and important content that the world needs to know about, but he takes you on an adventure with him right from your seat. He knows how to play off the audience and his confidence is organic and contagious. He is wonderful to work with – organized, dedicated and so much fun. I work with many speakers and by far he was one of the best decisions we ever made. If you’re looking for a speaker who gets conversations going beyond event day – look no further. He is authentic as authentic comes.

-Jess Teutonico, Executive Director, We Are Family Foundation and Curator, TEDxTeen


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.

Robert B. Richardson, PhD Michigan State University


We were privileged to have Rob speak at our annual Pacific Northwest Library Association conference. He was a challenging and entertaining speaker; the attendees loved it. Rob’s message about sustainability is relevant and timely for all libraries. I highly recommend both Rob as a speaker, and his book, Dude Making a Difference for libraries to have in their collection.

-Gwendolyn Haley, Past President of PNLA


Rob Greenfield’s presentation was awe-inspiring and inspirational for our 5th-grade environmental heroes. Months later, students are still referring to “the trash man” as we complete our all-school compost project. Now more than ever, our students understand the importance of reducing their waste and discouraging wasteful habits of others.

-Claire Brennan, Service Learning Coordinator at Friends Seminary


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


Rob was passionate, funny, engaging and, most importantly, right on point.  He instantly captivated the audience in his over-sized “trash suit”.  During his talk, he gave tips on how to aspire to a zero waste lifestyle and minimize the amount of trash that we produce.  Rob’s advice is authentic and resonated with the audience because not only can Rob articulately talk the talk, but he is committed to walking the walk.

Michele Dempsey, Friends of Lackawanna


Rob Greenfield brings with him a magnetic energy that you feel not only in his action and solution oriented message, but an energy that radiates in the room and ignites a passion in his audience as well. His presentation to my students left a lasting impression not only on them, but also the adults in the room because he doesn’t just present a problem, he empowers them with tangible solutions. He doesn’t just say to become part of the solution, he demonstrates exactly how. Rob is well-traveled and he brings his worldly experiences and knowledge to his interactions, which makes him very personable and able to connect with people almost instantaneously. I highly recommend Rob if you’re considering having him do a presentation at your organization because everyone present will walk away thinking and ready to act.

Pallavi Shastri, Green Team Coordinator P.S. 69Q, Jackson Heights, N.Y


Since our event with Rob, our community has had food waste on the agenda and we have seen a surge of interest in volunteers, local news articles, and changes in consumer behavior. Rob’s genuine passion for awareness building and his storytelling ability makes him an effective agent of change. I see tremendous benefit in having him speak with more communities across the nation to foster sustainable behaviors.

Christy Tweedy, Athens Community Council on Aging 


The local Authority Waste Prevention Network in Ireland was delighted to have Rob as their Key Note speaker at their annual plenary meeting. Whilst everybody in the room was already committed to waste prevention and sustainability, Rob provided great motivation and ideas to us all, to continue our work in community engagement. One of the key take home messages was that although the problems our planet face are huge, we cannot do nothing, and that each one of us should take responsibility for our own actions, something that Rob has clearly done.

Since the talk, a number of participants have used Rob’s ideas with events such as a food rescue event and a zero waste meal in a restaurant.

Nial O’Connor, Environmental Awareness Officer Monaghan County Council


Having Rob come and talk to the students about waste gave the hope needed to make change. Students knew a lot about all the negatives of climate change and waste and many viewed the ‘solution’ as large and unachievable. Rob was able to provide meaningful and realistic changes students could do right away, so they did! As a class they decided to all give up using plastic straws straight away, this was the seed needed to allow further action to happen as children and young adults. What made it special was it all came from Rob’s own personal experience, giving everything a solid context. The whole session was pitched perfectly to the age and ability of the students and they loved hearing about his adventures and asking plenty of engaging questions.

Marcus James,  International School of Geneva Switzerland


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 months 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
