Business and Environmental Protection and Business Ethics Class 11: Pollution Control and Ethical Elements

Updated 17 October 2026 · Fact-checked

Business causes air, water, land and noise pollution. Pollution control is needed to reduce health hazards and the risk of liability, to save costs, to improve public image and to bring other social benefits. Business ethics are the socially determined moral principles that should govern business; the elements of an ethical firm are top management commitment, a published code, compliance mechanisms, involvement of employees at all levels and measuring results.

Understand Business and the Environment: Pollution, Its Control and Business Ethics (CBSE 11)

Environment means the total surroundings: natural resources (air, water, land, flora and fauna) and human-made things. Pollution is the injection of harmful substances into the environment.

Kinds of pollution caused by business.

Air pollution: smoke from factories and vehicles (carbon monoxide), leading to smog, global warming and health problems.
Water pollution: discharge of chemicals and waste into rivers and lakes, killing aquatic life and spreading disease.
Land pollution: dumping toxic industrial waste, damaging soil quality.
Noise pollution: noise from factories and vehicles causing stress and hearing loss.

Need for pollution control. (1) Reduction of health hazards such as cancer, heart and lung diseases; (2) reduced risk of liability, since firms can be made to pay damages for harm caused; (3) cost savings, because efficient processes use less fuel and produce less waste; (4) improved public image, since customers prefer environment-friendly firms; (5) other social benefits such as cleaner surroundings and a better quality of life.

Role of business in environmental protection. A definite commitment by top management; commitment of the whole organisation; clear policies on purchasing, waste disposal and production processes; participation in government programmes (hazardous waste management, river cleaning, afforestation); periodic assessment of pollution control; educating dealers, suppliers and consumers.

Business ethics. Ethics concerns what is socially desirable, right and wrong. Business ethics are the socially determined moral principles that should govern business activities: no unfair prices, no adulteration, fair wages, honest advertising and fair dealing with competitors. Ethics goes beyond law: something can be legal but unethical. Ethical behaviour builds trust with customers, workers and society.

Elements of business ethics.
1. Top management commitment: the chief executive and senior managers openly commit to ethical conduct and lead by example.
2. Publication of a code: a written code of conduct covering honesty, adherence to law, product safety and quality, workplace health and safety, conflicts of interest, employment practices, fair marketing and financial reporting.
3. Establishment of compliance mechanisms: attention to values in recruiting, communication systems, and channels for employees to report unethical behaviour.
4. Involving employees at all levels: small groups and discussions make ethics a reality.
5. Measuring results: auditing compliance with the standards and taking corrective action.
