Is the debate about the financial value of sustainability over?

As corporate sustainability efforts become more complex and scrutinized, making a credible business case for environmental and social sustainability has never been more urgent. Economic volatility, political backlash and heightened investor expectations are forcing leaders to ask harder questions about where sustainability fits within core business strategy.

A new study, Project ROI: Determining the Competitive and Financial Advantages of Corporate Responsibility and Sustainability 2025, makes a clear and evidence-based claim: when executed well, sustainability drives financial performance.

The study updates an original analysis conducted a decade ago and synthesises findings from 640 leading academic and think-tank studies, with a primary focus on research published in top journals over the past 10 years across conventional business disciplines.

The research assesses the impact of sustainability on core business indicators, including share price, sales growth, profitability, costs and productivity. Importantly, it examines not only correlations but also whether – and how – sustainability initiatives causally contribute to superior financial outcomes.

The headline findings are striking. Environmental and social sustainability is associated with measurable financial performance gains, including up to:

These results, however, accrue only when sustainability is designed and managed as a strategic business capability. Project ROI finds that companies that succeed consistently follow three core steps.

Companies that unlock financial value from sustainability start with a persuasive business narrative. Skepticism remains widespread, with critics often framing sustainability as a cost or regulatory burden rather than a source of advantage. For many executives and investors, this argument still feels intuitive.

Project ROI offers a counter-narrative that is just as intuitive. At its core is trust. Who would you rather do business with? A company that is accountable for its impacts on people, communities and the environment or one that is not?

The research finds that sustainability helps improve trust and favourability with customers, investors, employees and high-quality suppliers.

Importantly, the study finds that sustainability decisions are shaped as much by emotion as by analysis. Leaders interpret sustainability through different lenses, described as six “sustainability archetypes” ranging from immediate returns to brand, reputation, risk and innovation.

Understanding these archetypes is critical. Leaders focused on brand and reputation, for example, respond more strongly to narratives that link sustainability to customer trust and product quality, as Patagonia has consistently demonstrated.

Next, high-performing companies align sustainability to the business through a disciplined process that Project ROI describes as “fit, commit, manage and connect.”

Fit

“Fit” aligns sustainability with core business strategy and operations. Determining material sustainability issues is a starting point but leading companies go further by identifying “sustainability tensions”: conflicts between financial, environmental and social priorities.

Leaders use these tensions to uncover “sweet spots” that turn conflict into a competitive advantage. Circularity provides a clear example.

The World Economic Forum and its partners find that by adopting circular supply chains, automakers could increase profitability by up to one-and-a-half times while significantly reducing environmental impact.

Where no immediate sweet spot exists, effective leaders determine when it makes sense to prioritize people and planet over profit, when profit comes first, and how to address temporarily delayed topics in the near future.

Commit

“Commit” requires directing the vast majority of sustainability operating expenditure (OpEx) toward an integrated strategy with explicit financial value propositions and clear performance targets. Project ROI identifies three core value propositions that repeatedly drive results:

Offering sustainability as a feature means embedding sustainability into the brand and business model. Sustainability becomes part of the brand promise to customers. E.g. Hewlett-Packard Enterprise integrates sustainability into B2B sales and customer engagement; it estimates that sustainability contributed nearly $585 million in net revenue over a fiscal year by strengthening customer relationships, supporting new business tenders and enhancing talent attraction and retention.

Use sustainability to drive down costs through efficiency, waste reduction and optimized capital allocation. E.g. Apollo Global Management reports that portfolio companies targeting a 15% reduction in carbon intensity found over $44 million in cost savings and $52 million in avoided risk-related costs.

Grow through sustainability offerings by developing products and services that address environmental and social challenges. E.g. BASF generated €24.1 billion in sales from its “Accelerator” products: offerings that make a substantial sustainability contribution within customer value chains.

Manage

“Manage” involves rigorously measuring results and designing an approach to sustainability that resolves tensions it may impose on the company’s organizational culture. Managing sustainability requires dealing with ambiguity.

Entrepreneurial cultures often embrace ambiguity, whereas conventional cultures struggle with it. Successful companies find a balanced management approach.

Connect

“Connect” involves understanding and aligning sustainability strategy to the expectations of key business and civil society stakeholders. Companies should seek to lead the pack on sustainability topics associated with high stakeholder expectations. Companies should also build awareness and build stakeholder allies.

Project ROI’s findings provide a foundation for rigorously measuring outcomes and translating insights into continuous improvement. For example, several companies have used the data to forecast benefits and report financial ROIs of 20–33% from sustainability initiatives.

The implication of this thorough research is clear: the debate over whether sustainability creates business value is largely settled. The priority now is execution: using sustainability deliberately to deliver value for profit, people and planet at scale.
