The 25 Most Influential Sustainability Leaders In The World

Who are the environmental and corporate sustainability leaders that are changing the status quo?

Sustainability leaders understand that sustainability is not just a buzzword; it’s a fundamental approach to business and everyday life in a way that benefits all.

But what exactly is a sustainable leader? How would you define this model citizen?

To us, a sustainability leader is an individual that demonstrates a strong commitment and proactive approach to implementing sustainable practices, promoting sustainability awareness and education, and leading by example.

And someone  can achieve that distinction through vastly different approaches across any industry.
Here you’ll find a cross-section of those individuals, experts and ultimately sustainable leaders in their respective fields—from sustainable business leaders to those who are out on the streets inspiring others to take up the mantle of environmental responsibility alongside them.

Leaders In Environmental Sustainability

1. Dr. Robert D. Bullard 

One of the world’s most respected Black leaders in sustainability, Dr. Robert D. Bullard is an American scholar, activist, and author who is widely regarded as the “father of environmental justice”.

His activism began in the 1970s, when he began researching and campaigning against the placement of hazardous waste sites in African American communities in Houston, Texas. These efforts were groundbreaking in establishing the link between systemic racism and environmental oppression.

His work eventually led to former President Bill Clinton signing the Executive Order on Environmental Justice in 1994, a doctrine still being built upon by current US government officials.

Over four decades, he’s published over 18 books, served on environmental advisory boards (such as the National Environmental Justice Advisory Council which advises the US Environmental Protection Agency), and won numerous awards, including the UNEP’s 2020 Champions of the Earth Lifetime Achievement Award.

2. Greta Thunberg

What do you get when you cross a young environmentalist, sustainable development goals, and a lot of passion for the planet?

Greta Thunberg. 

One of the most famous sustainability leaders, despite her young age, Thunberg began her eco-warrior career by skipping school to protest outside the Swedish parliament, calling for more ambitious action to address climate change.

Since then, she’s become a prominent spokesperson for the youth-led climate movement and has addressed numerous international conferences and events, including the United Nations Climate Action Summit and the World Economic Forum. 

She’s also been involved in several high-profile climate strikes and protests, inspiring millions of young people around the world to take action and already earning herself a TIME Person of the Year award in 2019.

While her list of achievements may not (yet) be as long as others on this list, her passion and young age is key in inspiring future sustainability leaders with a simple message: you don’t have to be old, famous or already accomplished to give voice to the planet.
