Ethics, law and sustainability, and writing a business brief

Businesses operate within a framework of laws and within society's expectations about right and wrong. A firm that breaks the law faces fines, lawsuits and sometimes criminal charges; a firm that acts legally but unethically can still lose customers, employees and investors. This final lesson covers business ethics and how to reason through ethical dilemmas, the legal environment of business, corporate social responsibility, sustainability and ESG reporting, and then brings the whole course together in a capstone: writing a one-page business brief.

Business ethics

Ethics is the study of right and wrong conduct. Business ethics applies ethical principles to business decisions, such as how to treat customers, employees, suppliers and communities, how to compete and how honestly to report results. The law sets a minimum standard; ethics often asks for more. Many practices are legal but widely seen as wrong, such as burying important terms in fine print or exploiting a supplier's dependence.

Ethical problems in business often arise from pressure to meet targets, conflicts of interest (when a personal interest could influence a professional decision), rationalizations such as 'everyone does it' or 'no one will be hurt', and organizational cultures that reward results without asking how they were achieved. Common issues include bribery, fraud and misleading financial reporting, false advertising, privacy breaches, unsafe products, discrimination and harassment, and poor treatment of workers in supply chains.

Reasoning through a dilemma

Several ethical frameworks help analyze a decision. A utilitarian approach asks which option produces the greatest good for the greatest number. A rights-based approach asks whether an option respects the rights of everyone affected, such as rights to privacy, safety and fair treatment. A justice or fairness approach asks whether benefits and burdens are distributed fairly. A virtue approach asks what a person of good character would do. When the frameworks agree, the answer is usually clear; when they conflict, the dilemma is real and requires judgment.

A practical process: get the facts; identify the stakeholders and how each is affected; list the options; test each against the law, the company's code of conduct and the frameworks above; ask whether you would be comfortable if the decision were reported on the front page or explained to someone you respect (the newspaper test); choose and act; and reflect on the result.

Many companies support ethical behavior through a written code of conduct, ethics training, leaders who model integrity, anonymous hotlines and protection for whistle-blowers who report wrongdoing.

In the United States, the Sarbanes-Oxley Act and the Dodd-Frank Act protect employees who report securities fraud, and the SEC's whistle-blower program pays awards of 10 % to 30 % of sanctions over $1 million collected thanks to original information.

The legal environment of business

Businesses deal with many areas of law. Some of the most important for a new manager are:

• Contract law: a contract is a legally enforceable agreement. It generally needs an offer, acceptance, consideration (something of value exchanged), capacity of the parties and a legal purpose. Important contracts should be in writing.
• Tort law: torts are civil wrongs, such as negligence, that cause harm. Businesses can be liable for injuries caused by their products or by employees acting in the course of their work, which is why they carry liability insurance.
• Product liability and consumer protection: laws that require safe products and fair dealing with consumers.
• Intellectual property: patents protect inventions, generally for 20 years from filing; trademarks protect brand names and logos; copyright protects original creative works; trade secrets protect confidential business information.
• Competition law: laws against price-fixing, bid-rigging, abuse of dominance and anticompetitive mergers.
• Employment, privacy, environmental and tax law.

In the United States, most contract, property and tort law is state law. Every state except Louisiana has adopted the Uniform Commercial Code's rules for sales of goods in some form. Federal law covers areas such as antitrust, bankruptcy, patents and copyrights, securities and interstate commerce. The Federal Trade Commission and the Department of Justice enforce antitrust law, and the US Patent and Trademark Office registers patents and trademarks.

Bribery of foreign officials is illegal for Canadian and US businesses anywhere in the world, under Canada's Corruption of Foreign Public Officials Act and the US Foreign Corrupt Practices Act. Both laws can bring large fines and prison sentences.

Corporate social responsibility

Corporate social responsibility (CSR) is the idea that businesses have obligations to society beyond making a profit and obeying the law. One well-known model describes four layers of responsibility: economic (be profitable), legal (obey the law), ethical (do what is right and fair) and philanthropic (contribute to the community). Supporters argue that responsible firms attract customers, employees and investors and reduce risk. Critics, following Milton Friedman, argue that a company's social responsibility is to increase profits within the rules of the game, and that spending shareholders' money on social causes is for governments and individuals to decide. Many firms now frame the debate in terms of creating shared value: finding business opportunities in solving social and environmental problems.

Sustainability and ESG

Sustainability means meeting present needs without compromising the ability of future generations to meet theirs. For businesses, it includes reducing greenhouse gas emissions, energy and water use and waste, sourcing responsibly and designing products for reuse and recycling. The triple bottom line asks firms to measure performance on people, planet and profit. Investors increasingly assess companies on environmental, social and governance (ESG) factors, such as emissions, labor practices, board independence and executive pay, though ESG investing has also faced political backlash and criticism over inconsistent ratings and greenwashing (making misleading environmental claims).

At the time of writing (October 2026), the SEC's 2024 climate disclosure rule is not in effect: the SEC stopped defending it in court in 2025. California has enacted laws requiring large companies doing business in the state to disclose greenhouse gas emissions and climate-related financial risks, with phased deadlines that have been subject to litigation, and companies with European operations face EU reporting rules. The FTC's Green Guides set out how environmental marketing claims should be substantiated.

Capstone: writing a one-page business brief

A business brief is a one-page summary that explains a business or a proposal clearly enough for a busy reader, such as a banker, investor or senior manager, to decide whether to read further. Writing one draws on everything in this course. A strong brief covers:

• The opportunity: the customer problem and evidence that it is real (lesson 1, lesson 7).
• The offer and value proposition: what you sell and why customers will choose you (lesson 1, lesson 7).
• The market and competition: size, trends, competitors and economic conditions (lesson 2, lesson 4).
• Legal form and ownership (lesson 3).
• Operations and people: how you will deliver, key staff and suppliers (lessons 5, 6 and 8).
• Financials: price, unit economics, break-even, start-up costs and funding needed (lessons 4, 9 and 10).
• Risks, including trade, legal, ethical and sustainability risks, and how you will manage them (lessons 11 and 12).

Keep the brief to one page, lead with the most important point, use numbers instead of adjectives, state assumptions clearly and make sure the figures add up. A reader should finish it knowing what the business does, why it will work, what it needs and what could go wrong.
