Updated for the 2026-2027 CFA® Level I curriculum.
Investors do not evaluate a company using financial statements alone. Many also look at environmental, social, and governance (ESG) factors to understand risks and opportunities that traditional metrics miss.
For CFA Level I, you need to describe these factors at the issuer level and explain why investors care about them. This note stays focused on the company itself, not on how portfolio managers build ESG strategies across a fund.
Quick Answer
ESG factors are issuer-specific characteristics that fall into three categories: environmental (resource use, emissions, waste), social (labor practices, product safety, community relations), and governance (board structure, executive pay, shareholder rights).
Investors consider these because they can affect a company's costs, legal exposure, reputation, and long-term performance. In finance, ESG analysis is an input to investment decisions, not a separate ethical scorecard.
Key Takeaways About ESG Factors
ESG factors are issuer-level characteristics investors use to assess risk and opportunity, not a standalone ethics rating.
Environmental factors cover a company's impact on and exposure to the natural environment.
Social factors cover how a company treats employees, customers, suppliers, and communities.
Governance factors cover how a company is directed and controlled, including board oversight and shareholder rights.
ESG factors can affect cash flows, cost of capital, and reputation, which is why investors treat them as financial inputs.
Not every ESG factor matters equally for every company. Materiality depends on the industry and business model.
A common mistake is treating ESG analysis as portfolio construction. At this level, the focus stays on the issuer.
What You Need to Know for CFA Level I
Define ESG and identify which category a given issuer-level example belongs to.
Explain why investors treat ESG factors as relevant to financial analysis, not just ethical preference.
Distinguish environmental, social, and governance factors using specific company-level examples.
Connect ESG factors to risk, cost, reputation, and long-term operating outcomes where the curriculum supports that link.
Recognize that ESG integration methods used across a portfolio belong to Portfolio Management, not this reading.
What ESG Factors Do Investors Consider?
ESG factors are characteristics of a corporate issuer that go beyond standard financial statement data. Investors consider them because they can signal risks or advantages that show up later in earnings, costs, or valuation.
The three categories break down like this:
Category | Focus | Investor Concern |
|---|---|---|
Environmental | The company's effect on and exposure to natural resources | Regulatory costs, physical risk, resource dependency |
Social | How the company manages relationships with people | Labor disputes, product liability, brand reputation |
Governance | How the company is directed and controlled | Board effectiveness, incentive alignment, shareholder protection |
An issuer with strong ESG characteristics is not automatically a better investment. The point is that ESG factors add information. A company with weak governance may face higher risk of fraud or poor capital allocation, even if its financial ratios look fine today.
Environmental Factors
Environmental factors describe how a company's operations interact with the natural environment. Common issuer-level examples include:
Greenhouse gas emissions from manufacturing or transport
Water use and waste management practices
Exposure to physical climate risk, such as flooding or drought affecting facilities
Dependence on finite natural resources, such as oil or rare metals
A mining company faces different environmental exposure than a software company. Investors weigh these factors based on the issuer's actual operations, not a generic checklist.
Social Factors
Social factors describe how a company manages relationships with employees, customers, suppliers, and the communities where it operates. Common issuer-level examples include:
Workplace safety records and labor practices
Product safety and quality control
Data privacy and customer protection
Supply chain labor standards
A company with repeated product recalls carries social risk that can show up as lawsuits, lost sales, or regulatory fines. Investors read social factors as early signals of these outcomes.
Governance Factors
Governance factors describe how a company is directed and controlled. This includes:
Board independence and expertise
Executive compensation structure and incentive alignment
Shareholder voting rights and ownership structure
Internal controls and audit quality
Governance connects directly to the principal-agent problem covered elsewhere in Corporate Issuers. A board that lacks independence may approve decisions that benefit management over shareholders. This note focuses on identifying governance factors themselves. The mechanics of stakeholder conflict are covered in the dedicated note on principal-agent relationships.
How ESG Factors Affect Investment Analysis
ESG factors matter to investors because they can influence financial outcomes, even when they do not appear directly on a balance sheet. These ESG considerations can affect how investors assess an issuer's risk and long-term prospects.
Risk assessment. Weak environmental controls can lead to fines or cleanup costs. Poor governance can lead to mismanagement or fraud.
Cost of capital. Companies seen as high ESG risk may face a higher cost of debt or equity if lenders and investors demand compensation for that risk.
Reputation and demand. Social issues, such as poor labor practices, can reduce customer loyalty or invite boycotts.
Long-term operating outcomes. Environmental and social factors can affect a company's ability to operate in certain markets or maintain licenses.
The materiality of each factor depends on the company. A utility company faces significant environmental exposure. A financial services firm may face more governance-related risk. Candidates should match the ESG factor to the issuer's actual business model rather than applying a fixed list of concerns to every company.
Common Exam Traps
Treating ESG as a moral score
ESG analysis is an investment input, not an ethics rating. The exam tests whether you understand ESG factors as tools for assessing risk and opportunity, not as a judgment of whether a company is "good."
Mixing issuer-level ESG factors with portfolio integration
This reading covers ESG factors at the company level. Techniques like negative screening or best-in-class integration across a portfolio belong to Portfolio Management. Do not import that material here.
Assuming equal materiality across companies
A factor that matters greatly for one industry may barely matter for another. Candidates who assume every ESG factor applies equally to every issuer will misread exam scenarios.
Confusing governance factors with general management quality
Governance refers to specific structures like board composition and shareholder rights, not a vague sense of "good leadership."
Ignoring the financial link
Some candidates describe ESG factors without connecting them to risk, cost, or reputation. The exam expects you to explain why the factor matters to an investor, not just name it.
Practice Question
A beverage company faces a lawsuit after reports show unsafe working conditions at one of its bottling plants. Which ESG category does this issue primarily represent, and how might it affect investor analysis?
Environmental factor, because it involves a manufacturing facility and may increase regulatory costs.
Social factor, because it involves labor practices and could increase legal and reputational risk.
Governance factor, because it reflects a failure of board oversight over plant operations.
Correct Answer: B
Unsafe working conditions are a labor practice issue, which falls under social factors. This can affect investor analysis through potential lawsuits, regulatory penalties, and reputational damage that may reduce sales or raise costs.
Option A. Incorrect. The issue involves worker treatment, not environmental impact like emissions or resource use. The plant setting does not make this an environmental factor.
Option C. Incorrect. Governance refers to board structure and oversight mechanisms. While weak governance can allow social issues to persist, the direct issue described is a labor and safety problem, which is social, not governance.

FAQs About ESG Factors Considered by Investors
Is ESG analysis part of financial analysis or a separate ethical judgment?
ESG analysis is a financial input. Investors use it to assess risk and opportunity alongside traditional metrics, not as a replacement for financial analysis.
Do all three ESG categories matter equally for every company?
No. Materiality depends on the industry and business model. An energy company may face more environmental exposure, while a bank may face more governance-related risk.
Is this the same as portfolio-level ESG integration?
No. This note covers ESG factors at the issuer level. Portfolio-level integration methods, such as screening or thematic investing, are covered in Portfolio Management.
