In 1970, the economist Milton Friedman published an essay in the New York Times Magazine with a title that reads like a provocation: "The Social Responsibility of Business Is to Increase Its Profits." His argument, compact and uncompromising, was that company executives who diverted shareholder resources to social purposes were effectively imposing a tax on shareholders without their consent -- an act of political overreach dressed up as virtue. Social problems should be addressed by government, not corporations.
Fifty years later, that argument has become the minority position in a conversation that has fundamentally shifted. Corporate social responsibility is now embedded in the strategic planning, annual reports, and public communications of virtually every large company. ESG investing channels trillions of dollars. Stakeholder capitalism has been endorsed by the Business Roundtable. CSR teams employ thousands of professionals. And the academic debate about whether any of it actually works -- or whether it is mostly performance -- continues unresolved.
This article examines what CSR is, where it came from, how it relates to ESG, what the best evidence shows about its effects, and why the philosophical debate beneath it still matters.
Defining Corporate Social Responsibility
Corporate social responsibility (CSR) is the broad concept that businesses have obligations to society beyond generating financial returns for shareholders -- obligations that may include environmental stewardship, ethical labor practices, community investment, and transparent governance.
There is no single universally accepted definition. The European Commission defines CSR as "the responsibility of enterprises for their impacts on society." The World Business Council for Sustainable Development describes it as "the continuing commitment by business to behave ethically and contribute to economic development while improving the quality of life of the workforce and their families as well as of the local community and society at large."
What these definitions share: CSR is voluntary (beyond legal requirements), stakeholder-oriented (concerned with multiple parties, not only shareholders), and integrative (embedded in core operations rather than separate from them, at least in aspiration).
In practice, CSR activities include:
- Environmental sustainability programs (emissions reduction, renewable energy, waste management)
- Community investment and philanthropy
- Employee welfare and development
- Ethical supply chain management
- Diversity, equity, and inclusion programs
- Transparency and governance practices
- Product safety and quality beyond minimum standards
Carroll's CSR Pyramid
The most enduring academic framework for CSR remains Archie Carroll's pyramid model, introduced in 1979 and elaborated in subsequent work. Carroll proposed that corporate responsibilities exist on four levels, stacked in a hierarchy:
Level 1: Economic Responsibilities
The foundation. Businesses exist to produce goods and services society needs and to generate profit in doing so. Economic viability is not merely a self-interested goal; it is the prerequisite for everything else. A company that cannot sustain itself financially cannot fulfill any other responsibilities.
Level 2: Legal Responsibilities
Obey the law. Society codifies its minimum expectations for business behavior in legal requirements: environmental regulations, labor law, product safety standards, anti-fraud provisions. Legal compliance is necessary but not sufficient for responsible behavior.
Level 3: Ethical Responsibilities
Do what is right and fair beyond what the law requires. Laws cannot anticipate every situation or codify every moral expectation. Ethical responsibilities involve acting consistently with what society expects in terms of fairness, honesty, and respect, even when no legal obligation exists.
Level 4: Philanthropic Responsibilities
Be a good corporate citizen. Contribute to the community, support education and the arts, donate to charitable causes. These activities are not strictly required by economic logic, law, or most ethical frameworks -- they are discretionary acts of corporate citizenship that society values but does not demand.
"The pyramid of CSR suggests that economic viability is the bedrock, with legal, ethical, and philanthropic responsibilities building upon it. A firm cannot be said to be socially responsible if it is not first economically viable." -- Archie Carroll, Business Horizons (1991)
| Level | Responsibility | Core question |
|---|---|---|
| 4 | Philanthropic | Are you a good corporate citizen? |
| 3 | Ethical | Are you doing what is right and fair? |
| 2 | Legal | Are you obeying the law? |
| 1 | Economic | Are you profitable? |
Carroll's model has been critiqued for its implicit hierarchy (suggesting philanthropy is the pinnacle of CSR) and for not capturing the strategic integration of social and environmental considerations. But it remains a useful pedagogical framework precisely because it orders the obligations and resists treating all four as equally fundamental.
The Friedman vs. Freeman Debate
The deepest fault line in CSR is philosophical, not empirical. It concerns the question: what is a corporation for?
The Shareholder Primacy View (Friedman)
Milton Friedman's 1970 argument rests on a specific view of corporate governance. Corporate executives are agents of shareholders. Shareholders own the company and have delegated authority to executives to manage it on their behalf. When executives spend corporate resources on social goods that are not directly linked to shareholder returns, they are acting outside their mandate -- using money that belongs to shareholders for purposes shareholders did not authorize.
This is not, Friedman emphasized, an argument against social responsibility per se. It is an argument about who should exercise it. Shareholders, as individuals, can donate money to causes they value. Governments, through democratic processes, can mandate corporate behavior. But a corporate executive who decides unilaterally to divert profits to social purposes is making a political decision with other people's money.
The economic logic: competitive markets allocate resources efficiently. Corporations that maximize shareholder value in competitive markets serve social welfare through that mechanism -- by producing what consumers want, at prices they are willing to pay, more efficiently than alternative arrangements. Adding a separate "social responsibility" layer on top introduces inefficiency and removes accountability.
The Stakeholder Theory View (Freeman)
Edward Freeman's stakeholder theory, developed in Strategic Management: A Stakeholder Approach (1984), begins from a different premise. A corporation is embedded in relationships with multiple groups whose interests shape its ability to create value: shareholders, yes, but also employees, customers, suppliers, communities, and governments. Each of these groups can affect the firm's ability to achieve its objectives, and the firm can affect theirs.
Managing stakeholder relationships is not an optional add-on to shareholder value creation; it is a precondition for it. Companies that exploit their suppliers damage supply chain reliability. Companies that ignore employee interests face turnover, disengagement, and talent deficits. Companies that damage their communities face regulatory, reputational, and recruitment consequences. Managing stakeholder interests well is good strategy.
Freeman's argument is not primarily ethical -- it is strategic. Stakeholder management is how you sustain long-term value creation, not a distraction from it.
Where the Debate Has Landed
The institutional landscape has shifted substantially toward the stakeholder view at the rhetorical level. In 2019, the Business Roundtable -- an association of CEOs of major US corporations -- issued a statement explicitly abandoning the primacy of shareholder returns and committing to obligations to all stakeholders. Larry Fink, CEO of BlackRock (the world's largest asset manager), has published annual letters arguing that companies must address societal purposes to achieve long-term financial success.
Critics point out that the behavioral evidence has not kept pace with the rhetoric. Research by Lucian Bebchuk and Roberto Tallarita found that the Business Roundtable signatories had not altered their corporate governance documents, executive compensation structures, or decision-making processes in ways that would actually constrain shareholder primacy. The statement may have been primarily reputational positioning rather than substantive commitment.
The empirical question -- whether stakeholder-oriented management produces better long-term returns than shareholder primacy -- remains contested. The theoretical question -- whether corporations ought to have social obligations beyond legal compliance -- is ultimately a political and ethical question that empirical research cannot resolve.
CSR vs. ESG: Understanding the Distinction
ESG (Environmental, Social, and Governance) is the investor-facing framework that has largely superseded "CSR" as the dominant vocabulary in financial markets, even as the two concepts overlap significantly.
What ESG Measures
ESG provides a structured set of criteria for evaluating corporate behavior in three categories:
Environmental: Carbon emissions and climate commitments, energy use and efficiency, water consumption, waste management, biodiversity impact, and supply chain environmental practices.
Social: Labor practices and worker safety, supply chain labor standards, diversity and inclusion, community relations, data privacy, and product safety.
Governance: Board composition and independence, executive compensation, anti-corruption policies, shareholder rights, tax transparency, and audit practices.
ESG ratings agencies (MSCI, Sustainalytics, S&P Global, among others) synthesize these criteria into scores that investors use for portfolio screening, risk assessment, and regulatory compliance.
How CSR and ESG Differ
CSR is a management concept -- about how companies should behave. ESG is a measurement framework -- about how investors assess how companies behave. A company with a strong CSR commitment may or may not score well on ESG ratings, depending on how well its activities map onto the specific metrics agencies use.
ESG has also been criticized for its metrics being inconsistent across rating agencies (the correlation between ratings from different ESG agencies is surprisingly low, around 0.4-0.6, compared to near-perfect correlation for credit ratings from different agencies) and for sometimes rewarding disclosure rather than actual performance.
| Dimension | CSR | ESG |
|---|---|---|
| Primary audience | Management, employees, community | Investors, regulators |
| Focus | Behavior and values | Measurement and risk |
| Origin | Management theory (1950s-70s) | Investment practice (1990s-2000s) |
| Accountability | Voluntary, reputational | Increasingly regulatory |
| Common criticism | Vague, hard to measure | Inconsistent, disclosure-focused |
Greenwashing: When CSR Becomes Theater
Greenwashing is the gap between the CSR and ESG commitments companies make publicly and what they actually do. The term was coined by environmentalist Jay Westerveld in 1986, in a critique of hotel towel-reuse programs that presented environmental symbolism while the hotels expanded in ways that consumed far more resources.
Modern greenwashing takes many forms:
Vague claims: "Eco-friendly," "natural," "sustainable," "green" -- terms with no standardized definition that signal environmental responsibility without committing to anything specific.
Selective emphasis: A company highlights a renewable energy pilot program while its core operations remain heavily carbon-intensive. The highlight is accurate; the overall impression is misleading.
Offsetting theater: A company claims carbon neutrality through the purchase of carbon offsets while making no reductions in its own emissions. The quality and additionality of carbon offsets varies enormously, and many have been found to be fictitious or ineffective.
Social washing: Equivalent selective emphasis on social metrics -- highlighting diversity achievements while concealing labor violations in the supply chain, for instance.
Future promises without present accountability: Net zero by 2050 commitments with no interim targets, accountability mechanisms, or current trajectory that makes the target plausible.
Regulatory Response
Regulatory scrutiny of greenwashing has intensified substantially in the 2020s:
- The EU Corporate Sustainability Reporting Directive (CSRD), which came into force in 2024, mandates much more detailed ESG disclosure from companies operating in the EU.
- The SEC's climate disclosure rule (adopted in 2024) requires publicly traded US companies to disclose material climate risks and greenhouse gas emissions.
- The UK Competition and Markets Authority's Green Claims Code sets standards for environmental claims in consumer marketing.
The regulatory direction is toward more specific, auditable disclosure and away from voluntary aspirational claims.
What the Research Shows: CSR and Financial Performance
The question of whether CSR "pays" -- whether companies with strong CSR programs outperform financially -- has been studied extensively and inconclusively.
The Meta-Analytic Evidence
The most comprehensive review is Friede, Busch, and Bassen's 2015 meta-analysis published in the Journal of Sustainable Finance and Investment. They analyzed over 2,200 individual studies covering the relationship between ESG criteria and corporate financial performance. Their headline finding: approximately 90% of the studies found a non-negative relationship, with the large majority (around 63%) finding a positive relationship.
This sounds like a clear endorsement of CSR as financially beneficial. The interpretation is more complicated.
Causation Problems
The most significant methodological challenge is reverse causation: companies that are financially successful may be better positioned to invest in CSR activities, rather than CSR activities causing financial success. The correlation may reflect that good companies are both profitable and socially responsible, not that social responsibility creates profitability.
Publication Bias
Studies finding positive relationships between CSR and financial performance are more likely to be published than null results. The literature may overstate the positive relationship for this reason.
Heterogeneity
The relationship is heavily moderated by industry, country, time period, and how "CSR" and "financial performance" are measured. Aggregate positive correlations conceal a lot of variation. In some sectors and contexts the relationship is clearly positive; in others it may be negative.
What Can Be Said With Confidence
The research does not support the claim that CSR systematically destroys shareholder value -- the strong version of the Friedman critique. It also does not support the claim that CSR is a reliable path to superior financial performance. The most defensible interpretation is that CSR programs, well designed and genuinely implemented, are broadly compatible with strong financial performance and may provide specific benefits (risk reduction, talent attraction, customer loyalty, regulatory goodwill) that are real but modest compared to the marketing claims of CSR advocates.
The companies that benefit most from CSR appear to be those where the CSR commitment is authentic and integrated into core strategy, not applied as a veneer on business practices that would otherwise be unchanged.
CSR in Practice: What Good Looks Like
The gap between CSR as rhetoric and CSR as genuine organizational change is substantial. Research and case analysis suggest several markers that distinguish genuine from performative CSR:
Integration with core business strategy: Patagonia's environmental commitments are not separate from its business -- they are built into its supply chain decisions, product design, and retail model. The body of the company reflects the stated values.
Material specificity: Genuine CSR involves commitments with specific metrics, timelines, and accountability mechanisms. "We are committed to sustainability" is not a CSR commitment. "We will reduce Scope 1 and 2 emissions by 50% by 2030 relative to 2019 baseline, with third-party verification" is.
Uncomfortable trade-offs: If CSR never requires the company to give something up, it is probably decorative. Real commitments sometimes conflict with short-term profitability, supplier relationships, or customer preferences. Genuine CSR absorbs those costs.
Governance alignment: Executive compensation tied to ESG metrics, board oversight of social and environmental performance, and audit processes for non-financial claims are markers of institutional commitment.
Supply chain rigor: Many companies' largest social and environmental impacts occur in their supply chains, not in their direct operations. Genuine CSR extends scrutiny into suppliers, not only to the company's own walls.
The concept of CSR remains more aspirational than achieved across the corporate landscape. The gap between declared commitments and actual behavior is large, as the greenwashing literature documents. But the gap is not uniform. Some companies have genuinely changed how they operate in response to social and environmental commitments. The analytical task is distinguishing those cases from the performance.
Frequently Asked Questions
What is corporate social responsibility?
Corporate social responsibility (CSR) is a business model in which companies integrate social and environmental concerns into their operations and interactions with stakeholders, beyond what is legally required. CSR encompasses philanthropic activities, environmental sustainability programs, ethical labor practices, community investment, and transparent governance. It reflects the idea that corporations have responsibilities to society that extend beyond generating returns for shareholders.
What is Carroll's CSR pyramid?
Archie Carroll's pyramid model, introduced in 1979, describes four levels of corporate responsibility stacked hierarchically: economic (be profitable -- the foundation), legal (obey the law), ethical (do what is right and fair, beyond what the law requires), and philanthropic (be a good corporate citizen and contribute to the community). Carroll argued these are not in conflict but in sequence: a company must first be economically viable to fulfill its other responsibilities. The pyramid has been widely taught and adapted for over four decades.
What is the difference between CSR and ESG?
CSR is the broad concept of corporate social responsibility -- the philosophy that businesses should act responsibly toward society and environment. ESG (Environmental, Social, Governance) is a framework for measuring and reporting on how companies manage specific categories of risk and impact: environmental (carbon emissions, water use), social (labor practices, diversity, community relations), and governance (board structure, executive pay, anti-corruption). ESG is effectively the investor-facing, quantitative measurement infrastructure built on top of the broader CSR concept.
What is greenwashing?
Greenwashing is the practice of making misleading or unsubstantiated claims about a company's environmental practices or the environmental benefits of a product. It ranges from vague claims ('eco-friendly', 'natural', 'sustainable') with no specific basis, to selective disclosure that highlights positive environmental actions while concealing harmful ones, to outright false claims. The term was coined by environmentalist Jay Westerveld in 1986. Regulatory attention to greenwashing has increased substantially in the 2020s, with the EU, FTC, and UK's Competition and Markets Authority all developing stricter standards.
Does CSR improve financial performance?
The research is mixed but generally finds a modest positive association. A 2015 meta-analysis by Friede, Busch, and Bassen covering over 2,000 empirical studies found that roughly 90% showed a non-negative relationship between ESG criteria and corporate financial performance, with the majority showing a positive relationship. However, causation is difficult to establish: financially successful companies may be better positioned to invest in CSR, rather than CSR causing financial success. The relationship also appears to be moderated by industry, measurement method, and time horizon.
