Sustainability is an important part of modern business, influencing how companies invest, develop products and plan for the future.
Businesses are expected to show how environmental and social commitments influence their actual decisions. This includes where they invest, how they use resources and how much of their revenue comes from products and services that support a more sustainable economy.
For students, professionals and future leaders, looking at companies recognised for their sustainability efforts offers a practical way to understand how responsible decisions connect with strategy, innovation and long-term growth.
Sustainability Trends in 2026
In 2026, there is a growing focus on measurable progress. Companies are being assessed not only on their commitments but also on how sustainability is reflected in their products, services, and wider business activities.
Sustainability is also visible across a wide range of industries, from energy and transport to healthcare, biotechnology and consumer goods. This shows that responsible business practices are relevant across different sectors and business models.
How Are the Companies Evaluated?
To understand the companies included in the table, it is useful to look at how their sustainability performance was assessed.
The ranking covers publicly listed companies with annual revenues of more than US$1 billion. For 2026, the evaluation focused on three main areas:
- sustainable revenue;
- sustainable investment; and
- the growth of sustainable revenue between 2022 and 2024.
From a business perspective, these criteria show whether sustainability is reflected in what a company earns, where it invests and how its activities are developing over time.

The table shows that sustainability leadership can take different forms across companies and markets. What connects these businesses is the way sustainability goals are reflected in measurable business results.
What Does the Ranking Show?
The ranking shows that sustainability is an important part of how companies grow, invest and create long-term value.
It also reflects its relevance across global markets, as businesses in different industries include responsible practices in their operations and decision-making.
For business leaders, this highlights the importance of understanding sustainability as part of business strategy, rather than as a separate initiative.
What Can Business Leaders Learn?
For business students and professionals, the ranking offers a practical way to examine how sustainability is measured across different companies and industries.
It draws attention to the connection between business models, investment decisions and long-term priorities. It also shows that companies may approach sustainability differently depending on their sector and market.
From a management perspective, the value of the ranking lies not only in the final positions, but also in the questions it raises about performance, progress and changing business expectations.
Why Business Education Matters
Understanding sustainability requires more than knowing which companies perform well in a ranking. It also means recognising the business questions behind those results, from how progress is measured to how different priorities are balanced.
For students and professionals, this creates an opportunity to look at sustainability through strategy, finance, innovation and leadership. It can also help them evaluate company decisions more critically and understand the wider impact those decisions may have.
At PSM, these connections form part of a broader approach to business education, helping future leaders develop the knowledge and judgement needed to navigate a changing business environment.
A Final Perspective
Sustainability rankings can offer a useful overview, but their results should be viewed in context and alongside other relevant information.
Their value lies in helping readers understand which aspects of sustainability are being measured and what the results may reveal about changing business priorities. They can also encourage a closer look at how companies approach responsibility, progress and long-term planning.
From a business education perspective, these rankings provide a useful starting point for discussion and help students, professionals and future leaders develop a broader understanding of sustainability in modern business.
