Read Richard's bio

Richard initially trained as a Physicist/Astrophysicist before transitioning into IT and Financial Services Industry. Then, founding his own company, Richard studied complex adaptive systems found in natural ecosystems and exploring how these concepts could be translated and applied to self-adaptive software systems.

Richard has been an environmentalist for as long as he can remember and actively participated in protests with Greenpeace Frontline in the early 1990s. In 2019, he ran as a Green Party candidate for Haywards Heath Town Council and successfully won the election. During his term, he spearheaded the development of an environmental strategy based on localism, with activities prioritized according to the principles outlined in the Drawdown project. One of the key components of this strategy was promoting a dietary shift towards plant-based foods and reducing food waste.

Under Richard’s leadership, Haywards Heath Town Council in July 2022, became the first town in Europe to sign the Plant-Based Treaty, so further cementing its commitment to a sustainable plant based future.

Mauritius Ambassador

Heather Drummond

Plant-based Educator in Mauritius and founder of Ecoshe

Read Heather's bio

At the age of 28, Heather lost her mother and sister suddenly, sparking a profound journey of self-discovery. Seeking answers, she found herself in an Ashram in India, where the yogis’ vegetarian lifestyle fascinated her. This led her to write “Dear River“, chronicling her transformative experiences in wellness and inspiring her to educate people and companies on the benefits of a plant-based diet and how delicious it can be. She started a non-profit called Ecoshe to do just this. Her mission is to cultivate a sustainable future, nurturing empathy and love while promoting plant-based knowledge worldwide.

Heather launched her inspiring 1.5 hour workshop at the VegFest UK in 2022 and won an award in the Eco Solution Category. The workshop shows a short documentary she produced and also a quiz app which very quickly highlights how imperative it is we shift as a society to kinder, more sustainable diets. Since then she has taught the workshop countless times to hundreds of non-vegans of which over 50% choose to reduce their meat, dairy and egg consumption. She is inviting people worldwide to first of all learn with her, then potentially teach with her and if they so desire live together in vegan communities. In every one of her workshops, she acquaints participants with The Plant-based Treaty and extends a warm invitation to endorse it. Her teaching engagements have taken her to prominent hotels in Mauritius and, more recently, to companies committed to achieving ESG goals, emphasizing the harmonious integration of people, planet, and profit.

Heather was born in Zimbabwe in 1976, however has been living in Mauritius for the last 10 years. In Zimbabwe, she founded a successful business exporting African Art and later joined her husband’s software development company Webdev. Their other ventures, include PropertyCloud in Mauritius. Presently, she dedicates herself entirely to Ecoshe and serves as a passionate ambassador for the Plant-based Treaty alongside her work.

I support the Plant Based Treaty wholeheartedly because I’m driven by the vision of a greener, more ethical world that cherishes all living beings and preserves our planet for generations to come. Understanding the WHY behind the plant-based movement makes the HOW both effortless and thrilling and I’m delighted to be a part of this movement.

Singapore City Ambassador

Ambaree Majumder

Social Entrepreneur, Speaker and Educator, Singapore

Read Ambaree's bio

Ambaree Majumder is a Social Entrepreneur, Speaker and Educator in the field of Plant based Nutrition as well as Food Sustainability from eCornell.

She advocates eating a diet rich in plants through her talks workshops that are based on scientific evidence on why it is crucial that we gradually move to a plant based lifestyle for better human health and environmental sustainability. She has spoken at schools, university, corporate organisation and on several global platforms in countries like the USA, Australia, Malaysia, India, the Philippines and Singapore.

She is also a member of Rotary Club of Marina City in Singapore and leading the region of Singapore in their efforts towards protecting the environment. She is the co-chair of a task force called Plant-Rich Diet under Environmental Sustainability Rotary Action Group.

The fact that we can still prevent a climate catastrophe to a large extent just by modifying our eating habits is ray of hope for us and our future generations. Although it seems like a simple solution, the journey to achieve it might be one of the most difficult ones. I believe that it is possible only through persistent awareness campaigns and policy amendments. Both of these goals seem within our reach through the Plant Based Treaty.

Youth Ambassadors

Nika Moeini


Policy change starts with making our voices heard. Young people will not only shape the future, but we will shape the present through our actions! We are leaders today, and must act on the greatest threat of our time: climate change.

Morgan Janowicz

Green REV Institute


We are on the edge of a climate catastrophe, yet we continue to conduct business as usual, afraid to make often radical but necessary decisions and ignore the science that ruthlessly shows us the reality in which we all find ourselves.

Brunna Sachs


If the world switched to plant-based food we wouldn’t have to deal with so many problems in the future! What we choose to put on our plates directly affects ecosystems, humans and the climate. Make the change now! The planet, animals and future generations thank you.

Health Ambassadors

I am honored to be a health ambassador for the Plant Based Treaty, which is rooted in the values of sustainability, health, compassion, and justice. Our food system negatively impacts individual health by contributing to our chronic disease epidemic, malnutrition, antibiotic resistance, and pandemic risk, as well as the health of our planet. As health professionals, we should be fiercely advocating for the health of our people and the planet on which we depend. There are no healthy individuals on an unhealthy planet. Plant Based Treaty represents a bold and inspiring vision to urgently transform the global narrative and influence policy at all levels toward a sustainable, just and healthful plant-based food system that is essential for our individual health, our planetary health, and our survival.

Media Ambassadors 

Robbie Lockie

they / them

Digital media expert, co-founder and co-director of
Plant Based News

Read Robbie's bio

Robbie Lockie is a digital media expert and influential figure within the global vegan movement. They are perhaps best known for being the co-founder and co-director of Plant Based News

Lockie was born in Zimbabwe, Africa, and started a career in digital design before relocating to London, England, in 1999.

Like most people, Lockie grew up eating meat – but they decided to try out a plant-based diet in 2013 after experiencing health problems. The switch had a hugely positive impact on them, which led Robbie to research other benefits of veganism. It was then that their eyes were opened to the immense suffering of farmed animals. 

Veganism has since become a major part of Robbie’s life. They founded Plant Based News alongside Klaus Mitchell in 2017, and the digital media platform has become the world’s leading source of vegan news. It has 80 million impressions a month, and almost 3 million followers on social media. 

Robbie is also the founder of the globally celebrated initiative World Plant Milk Day. They have produced a number of videos for animal rights organisation Viva!, including The Dairy Industry’s… TRASH and Swine. The latter explores antibiotic-resistant superbugs on factory farms.

Through all their valuable work, Robbie draws attention to how a vegan lifestyle can benefit animals, the environment, and our health. They also disseminate much-needed information that mainstream media often chooses to ignore. Truly “disrupting the conventional narrative.”

Care Home Ambassadors

Bill and Pat Russell

On February 1, 2023, Bill and Pat Russell happily agreed to “join the diplomatic corps” and become Plant Based Treaty ambassadors for care homes.

Human beings’ current practices of speciesism, the way we are dominating the planet, must come to an end.  As a veganic farmer and activist I have dedicated my time to show that there is a more compassionate way to walk on our collective earth. City by city, state by state, nation by nation we can live together harmoniously with each other and the natural world. We can end animal agriculture forever and transition to a 100% plant-based agricultural system. The Plant Based Treaty has my endorsement for they seek to enact on these principles whole-heartedly.
