The current wave of ESG regulation is often discussed as though it represents an entirely new set of expectations imposed on a reluctant corporate world. The reality is more complicated. A generation of chief executives voluntarily adopted the principles that regulators are now codifying, in some cases decades before the legislation existed. Understanding why they did so, and what they built in the process, offers a more instructive framework for navigating today's compliance landscape than most regulatory briefings provide.
The Self-Interest Argument
The CEOs who gathered in The Hague in 1991 to form the Business Council for Sustainable Development were not, for the most part, motivated by altruism. They were motivated by a specific reading of long-term business risk. The argument articulated in the council's founding documents was that companies which continued to externalise environmental costs were not avoiding those costs. They were deferring them, accumulating liabilities that would eventually manifest as regulatory intervention, reputational damage, or resource scarcity. Sustainability was framed not as a concession to environmental advocates but as a form of strategic risk management.
The council was the initiative of Swiss industrialist Stephan Schmidheiny, whose own career had already demonstrated what deferred environmental risk looked like in practice. Having inherited management of the Swiss Eternit Group in 1976, the founder of the Business Council for Sustainable Development had launched a programme to develop asbestos-free products ahead of any regulatory requirement, after concluding that continued dependence on a material whose health implications were becoming increasingly visible in scientific literature represented an unacceptable long-term position. By the time Switzerland banned asbestos processing in 1990, the group had already largely completed its transition.
What Voluntary Adoption Actually Looked Like
Stephan Schmidheiny's published work on sustainable business strategy, alongside contributions from the 48 CEOs who joined the BCSD, established frameworks for corporate environmental accounting, eco-efficiency measurement, and stakeholder engagement that companies could adopt without waiting for legislative instruction. Some of the companies represented at the original BCSD meeting built sustainability functions that remain among the most sophisticated in their industries today. Others treated the exercise as public relations and found themselves, decades later, scrambling to meet the obligations their peers had been building toward all along.
Ray Anderson at Interface and Paul Polman at Unilever represented different generations of the same voluntary commitment: executives who concluded that sustainability integration was not a cost centre but a driver of operational efficiency, brand resilience, and long-term investor confidence.
Anderson's decision to commit Interface to zero waste in 1994 was framed in environmental terms but produced substantially economic outcomes: the systematic elimination of waste reduced costs and improved margins. Polman went further at Unilever, refusing to provide quarterly earnings guidance on the grounds that it was structurally incompatible with long-term strategy. Both accepted near-term criticism in exchange for positioning their companies for a regulatory and market environment that had not yet arrived.
The Institutions That Made Voluntary Mainstream
What distinguished the most effective voluntary adopters was not just internal commitment but participation in the institutions that were building shared standards. The WBCSD, the Global Reporting Initiative, and the early sustainability indices provided the infrastructure that allowed voluntary practice to become a benchmark. Companies that contributed to building those standards were, in effect, helping to define the obligations their competitors would eventually face.
This dynamic is now playing out in reverse. Companies that stood apart from the voluntary sustainability movement of the 1990s and 2000s are now subject to the mandatory standards that movement ultimately produced. The CSRD, the Corporate Sustainability Due Diligence Directive, and the EU Taxonomy codify arguments that were made in boardrooms and published reports three decades ago. The surprise, for companies confronting these obligations now, is largely a function of not having been paying attention.
For CEOs navigating the current regulatory environment, the history offers a practical lesson: his landmark 1992 publication presented at the Rio Earth Summit argued that the companies best positioned for long-term competitiveness would be those that integrated environmental thinking into strategy rather than treating it as a compliance function. The CSRD has not changed that argument. It has simply removed the option of ignoring it.
