These top global MBAs for sustainability are maximizing impact

What’s the best way to have a genuinely positive impact on the world? It’s a question of growing urgency for many young people as our global challenges intensify. For many, the answer leads them to business school. 

The “impact” metric was introduced to the Corporate Knights MBA ranking several years ago as a bonus, but this year is the first that it has become part of the official ranking. Corporate Knights evaluated 179 programs and ranked the top 40 for their focus on sustainability. Ninety percent of the score these rankings are based on is awarded for the content of the curriculum, and now 10% has been awarded for impact – what schools’ alumni are doing post-graduation.

The school with the highest score on this measure this year was Bard College in New York, with an impact rating of 56%. Out of 62 graduates, Corporate Knights identified 35 who are either in sustainability roles or working at companies recognized for their sustainability efforts. By comparison, the average alumni rating was 16% among other schools that made the ranking. Only the University of Vermont’s MBA program had a comparable impact rating of 52%. 

For the last three years, Bard has consistently ranked in the top five MBA programs for sustainability. Bard stands out as one of the few business schools specifically designating its MBA as an MBA in Sustainability, another being the University of Vermont. “They are not shy about putting the program’s sustainability focus front and centre,” says Corporate Knights research analyst Muhammad Talha. 

We need our students out changing the world at scale in a hurry.

Bard’s graduates have compelling stories: a schoolteacher who went on to become a vice president of ESG (environmental, social and governance) for the Americas at Deutsche Bank within just one year of graduating; the emergency medical technician who became a managing consultant at the global firm Guidehouse. Perhaps the most famous example is Chelsea Mozen, who developed the idea for Etsy to offset its carbon emissions from shipping during her capstone project at Bard. Just four years after graduating, she was the chief sustainability officer for Etsy, making it one of the first major global companies to commit to a climate pledge.

“Our students’ interests range from food to fashion to energy. There’s a lot of variability,” says Eban Goodstein, an economist and the founder of Bard’s program. He explains that the program is highly experiential. “I think of it as a 24-day retreat spread out over three years,” he says. “It’s almost more like a fine arts degree where you are learning directly from artists.”

In Bard’s MBA, students begin working on real-world projects in their first year, often with major industry players. The goal, according to Goodstein, is not just to respond to, but entirely shift how we address – and prevent – mounting environmental and social challenges. “We need our students out changing the world at scale in a hurry,” he adds.

All of the MBA programs on the list open up a multitude of options to get that done. For many of these students, it means taking on a key corporate sustainability role at a global leading company, or launching their own enterprise with values of social responsibility and environmental sustainability embedded in the organization’s DNA. But in a different economy, the approach post-graduation might look very different.

2025 Better World MBA Top 40

Take, for example, the top-ranked “large” school, defined as a program with more than 80 graduates annually. This year, the spot belongs to Centrum’s PUCP in Peru. Centrum was one of just two South American schools on the top 40 list (the other, Colombia’s Universidad Externado, jumped from 112 in last year’s ranking to 40 in this year’s).

Centrum operates in a different context than the majority of schools in the ranking, which are overwhelmingly from the Americas or Europe. The Peruvian economy is largely “informal,” associate dean Sandro Sánchez explains. While many Centrum graduates are vying for corporate jobs (about 20 graduates of the last two years landed at companies like Vestas and Schneider Electric), the majority of these students go on to work in – or start – smaller companies, including those outside the urban centres in sectors like mining and agriculture, which remain the engines of the Peruvian economy. 

This is not the same business environment where you tend to see corporate sustainability officers or climate pledges. But this is precisely what makes this training so important. It’s here that graduates’ vision for social and environmentally positive change – a vision they develop in their MBA program – will have the greatest impact.

METHODOLOGY

The 2025 Corporate Knights Better World MBA Top 40 ranking examines the performances of 179 business schools, drawn from the most recent FT100 MBA Ranking, the Princeton Review Best Green MBA, the Top 40 from the 2024 Better World MBA ranking, and all current PRME Champions; and business schools accredited by the Association of MBAs, the AACSB (Association to Advance Collegiate Schools of Business) or the EFMD (European Foundation for Management Development) QualityImprovement System (EQUIS) and also signatories to the UN Principles for Responsible Management Education that opt in for evaluation. Based on publicly disclosed information on their websites, schools are evaluated on the sustainability content of their core courses and can review and request revisions to the analysis. Additionally, schools may voluntarily provide the number of recent graduates employed with impact organizations, which is worth 10% of the overall score.
