What Happens When Corporations Are Required to Revise Publicly — ESG and Beyond

The corporation is a legally created fiction whose power to organize productive activity has been the central economic mechanism of industrial capitalism. This power is real and enormous: the largest corporations organize more labor, more capital, and more material throughput than most national economies. The governance question that has never been satisfactorily resolved is: to whom are they accountable?

The shareholder primacy answer, which has dominated Anglo-American corporate governance since the 1970s, is that corporations are accountable to shareholders, whose interests are served by maximizing financial returns. This answer has the virtue of analytical clarity and the vice of excluding the vast range of parties whose lives are substantially affected by corporate decisions: employees, communities, ecosystems, future generations, and the society that provides the legal and physical infrastructure on which corporate activity depends.

The stakeholder theory response — associated with R. Edward Freeman and later institutionalized in the Business Roundtable's 2019 Statement on the Purpose of a Corporation — argues that corporations must balance obligations to multiple stakeholders. This is correct as a normative matter and largely empty as a governance mechanism. A corporation that commits to balancing stakeholder interests without specifying how those interests will be measured, what trade-offs will be made when they conflict, and what consequences will follow from failing to maintain the balance has committed to nothing specific. The Business Roundtable statement, signed by 180 CEOs, produced no measurable change in corporate behavior in the years following its publication.

The insight embedded in mandatory public disclosure requirements is that the accountability gap cannot be closed by voluntary commitment. Voluntarism works at the margins — where the reputational benefit of good behavior exceeds its cost — and fails systematically wherever the cost of accountability exceeds its benefit. What closes the accountability gap is information infrastructure that makes corporate conduct measurable, mandatory disclosure that makes the measurement public, verification requirements that prevent strategic misrepresentation, and legal liability that creates consequences for material misstatement.

This is the architecture of the accounting and financial disclosure system that governs financial performance. It is, notably, not voluntary: public companies are legally required to prepare audited financial statements under standard accounting principles, and executives face personal criminal liability for material misstatements. The ESG disclosure movement is attempting to extend this infrastructure — imperfectly, incompletely, and against significant resistance — to non-financial dimensions of corporate conduct.

ESG as a market phenomenon predates ESG as a regulatory requirement. The growth of socially responsible investment from a small niche market (primarily religious investors avoiding sin stocks) to a mainstream institutional investment framework (representing over $35 trillion in assets under management by 2020 estimates) drove demand for non-financial corporate information that the investment industry supplied through ratings agencies.

The ESG ratings industry — dominated by MSCI, Sustainalytics, Bloomberg ESG, and ISS — developed methodologies for measuring corporate environmental, social, and governance performance and compiling them into ratings used by investors to screen portfolios. This industry has produced useful information and significant confusion simultaneously, reflecting several structural problems.

Methodological divergence: Different ratings agencies using different weightings, different data sources, and different measurement approaches produce substantially different ratings for the same company. A 2022 study found that ESG rating correlations between major providers were lower than 0.5 — meaning that a company rated excellent by one provider might be rated poor by another. This divergence is not merely measurement error; it reflects genuine disagreement about what ESG means and how to weight its components.

Data quality limitations: Most ESG data comes from company self-disclosure, which creates obvious incentives for strategic presentation. Companies choose which metrics to disclose, in what formats, at what levels of granularity, and with what context. They can select favorable performance periods, choose comparison benchmarks that make their performance look stronger, and omit the specific data points that would reveal problems.

Outcome vs. process metrics: Much ESG measurement focuses on process indicators — does the company have an environmental policy? Does it have a supplier code of conduct? Does it conduct diversity training? — rather than outcome indicators — what are its actual emissions? What are actual labor conditions in its supply chain? What is actual workforce diversity at senior levels? Process metrics can be accumulated by companies with genuinely poor outcomes.

The "best in class" problem: ESG ratings typically compare companies within sectors, so an oil company that handles its environmental impact better than its peers may receive a high ESG rating despite its absolute environmental impact being severe. This relative measurement is appropriate for some investment purposes but obscures the question of whether corporate environmental performance in aggregate is improving.

These distortions are not arguments against ESG disclosure — they are arguments for better disclosure architecture. The information the ratings industry attempts to create is genuinely needed; its voluntary, uncoordinated production by a fragmented private industry is simply not the right mechanism for creating it reliably.

The shift from voluntary market-driven ESG disclosure to mandatory regulatory disclosure represents a qualitative change in the accountability mechanism. The leading examples of this shift illuminate both the potential and the implementation challenges.

The EU Corporate Sustainability Reporting Directive (CSRD): The most comprehensive mandatory non-financial disclosure framework yet enacted, the CSRD applies to approximately 50,000 companies operating in the EU — including non-EU companies with significant EU revenue — and requires disclosure against detailed European Sustainability Reporting Standards covering environmental, social, and governance topics. Critical features distinguish it from voluntary disclosure: standardized metrics that allow cross-company comparison, mandatory third-party assurance at a limited level initially progressing to reasonable assurance, digital tagging that allows machine-readable data and systematic analysis, and coverage of the double materiality concept — requiring companies to disclose both how sustainability issues affect their financial performance and how their activities affect sustainability.

The double materiality concept is particularly significant. Traditional financial materiality asks: what does the outside world do to our finances? Double materiality adds: what do we do to the outside world? This is a conceptual shift from investor-oriented disclosure to society-oriented disclosure. A company's carbon emissions are material under double materiality even if the regulatory environment has not yet priced carbon at a level that materially affects earnings, because the emissions' effect on the climate is material regardless of the company's financial exposure.

The CSRD's revision mechanism is clear: companies that must publicly disclose standardized, verified metrics across dozens of environmental and social performance areas face internal pressure to manage those metrics. Environmental managers who must sign off on assured emissions data have different conversations with operations executives than environmental managers who prepare voluntary reports. The assurance requirement — bringing auditors into the sustainability disclosure process — creates legal liability that changes the incentives around what is disclosed and how.

The SEC Climate Disclosure Rules: The Securities and Exchange Commission's 2024 climate disclosure rules (partially stayed pending litigation) would require public companies in the United States to disclose material climate-related risks, greenhouse gas emissions in certain categories, and information about climate risk management. The rules apply the existing financial disclosure framework — materiality standard, management liability, auditor involvement — to climate information, integrating it into existing reporting structures rather than creating a separate sustainability report.

The litigation response to the SEC rules illustrates the political economy of mandatory disclosure: industries and companies that have benefited from information asymmetry — communicating climate commitments voluntarily while not being legally accountable for them — have strong incentives to prevent disclosure requirements that would create accountability. The legal challenge to the rules is therefore not primarily a technical dispute about regulatory authority (though it presents as one) but a contest over whether corporations can be compelled to provide verifiable, legally accountable climate information.

The German Supply Chain Act (Lieferkettensorgfaltspflichtengesetz, 2021): This legislation extends the disclosure and accountability framework beyond the reporting company's own operations into its supply chain. Large German companies must conduct risk analysis of their supply chains for human rights and environmental violations, implement mitigation measures, and report publicly on their due diligence processes. Crucially, it creates civil liability pathways for harms caused by supply chain violations — moving beyond disclosure toward genuine accountability.

The supply chain due diligence approach addresses a fundamental limitation of emissions-focused ESG frameworks: companies can reduce their own reported footprint by outsourcing the environmental and social costs of their operations to suppliers in jurisdictions with weaker regulations. Supply chain due diligence requirements close this arbitrage by extending accountability to controlled supply chain conditions.

The political reaction against ESG in the United States, primarily from Republican-aligned officials and politicians who characterized it as "woke capitalism" or anti-energy policy, illuminates what mandatory public disclosure actually threatens.

The reaction is not primarily about the quality of ESG metrics or the methodology of ratings agencies, though these are cited. It is about the underlying accountability logic. If corporations are required to publicly disclose material environmental and social impacts — and if institutional investors, regulators, and citizens can use this information to apply pressure — the information asymmetry that has allowed companies to externalize costs while privatizing benefits is reduced. The political interests aligned with that information asymmetry — carbon-intensive industries, companies with supply chain labor practices that would not survive public scrutiny, executives whose compensation structures depend on decisions that impose costs on others — have rational interests in preventing mandatory disclosure.

The anti-ESG political movement has been partially effective: it has created political costs for major asset managers (BlackRock, State Street, Vanguard) whose ESG commitments attracted congressional scrutiny, prompted several states to restrict the use of ESG criteria in state pension investment, and created political pressure that has slowed SEC rulemaking. It has not reversed the underlying trajectory, partly because the EU's requirements apply to global companies and cannot be opted out of through U.S. political action, and partly because institutional investors' interest in ESG data as a risk management tool is not primarily ideological.

The ESG framework is the current frontier of corporate accountability requirements, but it is not the logical endpoint. Several developments suggest where the next generation of requirements is heading.

Nature-positive accounting: The Taskforce on Nature-related Financial Disclosures (TNFD) is developing a framework for corporate disclosure of nature and biodiversity dependencies and impacts, paralleling the climate-focused TCFD. As regulatory and market attention to biodiversity loss intensifies, companies will face increasing pressure to disclose and manage their nature-related impacts — a substantially more complex measurement problem than carbon accounting.

Scope 3 emissions and full value chain accountability: Scope 3 emissions — those generated throughout a company's value chain, both upstream in supply chains and downstream in product use — represent the majority of most companies' climate impact but are the most difficult to measure and the most politically contested to disclose. As disclosure regimes mature, the progressive expansion of scope to cover full value chain impacts is the most likely trajectory.

Social accounting and genuine community impact: Current social disclosure frameworks focus primarily on workforce demographics, compensation, and safety — important but partial. More comprehensive social accounting frameworks would attempt to measure companies' net impact on communities: economic multiplier effects of wages and purchasing, tax contributions versus tax avoidance, displacement effects on existing businesses, and long-run community economic health. This is methodologically challenging but conceptually clear: if we want to know whether a company is beneficial or harmful to the community it operates in, we need to measure the relevant outcomes.

Legal accountability integration: The progression from disclosure to liability — where the German Supply Chain Act is the leading example — represents the next structural step. Disclosure without enforcement creates accountability theater; disclosure with genuine legal consequences for verified harms creates accountability. The EU's forthcoming Corporate Sustainability Due Diligence Directive, which extends the supply chain due diligence and liability model to environmental harms, represents this progression.

The civilizational argument for mandatory corporate public revision is not primarily economic or environmental — it is about the basic conditions of legitimate economic organization.

Corporations operate within legal frameworks that the public creates and maintains. They use public infrastructure — roads, ports, educated workforces, stable currency, enforceable contracts, property rights — that the public provides. They impose costs on communities and ecosystems that they do not pay for when those costs are externalized. The implicit bargain of incorporation — that the state creates a legal person with limited liability, perpetual existence, and powerful organizational capabilities — has always included some obligation to the public that created it.

The specific terms of that obligation have been contested since corporations first existed. The current ESG moment is one episode in a longer history of revising the terms: from child labor regulations to occupational safety requirements to environmental impact assessments to equal employment opportunity law, each generation has revised the conditions under which corporate activity is permitted to occur, typically expanding the accountability required.

Mandatory public disclosure of environmental, social, and governance performance is the contemporary form of this ongoing revision. It does not solve the problem of corporate externalities — only regulatory requirements with enforcement will do that — but it creates the information infrastructure without which regulatory solutions cannot be calibrated, political pressure cannot be directed, and markets cannot price what they do not know.

A civilization in which large corporations must revise publicly — must measure and disclose their actual impact, submit to third-party verification, and stand accountable in law for material misstatements — is a civilization that has created the minimum conditions for corporate accountability. A civilization in which they do not must accept the consequences: externalities that accumulate invisibly, commitments that are made and quietly abandoned, and the systematic privatization of the benefits and socialization of the costs of the most powerful economic institutions in history.

The revision is ongoing. Its adequacy will be determined not by the quality of the reporting standards but by the quality of the enforcement mechanisms and the political will to maintain them. Disclosure without consequences is theater. Disclosure with consequences is accountability. The civilizational work is building the second and preventing the first from substituting for it.
