6. Environmental Economics
Learning Objectives
- Explain how economics frames environmental problems such as pollution, resource depletion, and climate change
- Identify the key policy instruments India uses to control pollution and protect natural resources
- Analyse the trade-offs between economic growth and environmental sustainability in the Indian context
- Evaluate the concept of Green GDP and explain why it matters more than conventional GDP for India
- Distinguish between mitigation and adaptation strategies in India's climate change response
- Connect India's environmental laws and policies to real outcomes for citizens and ecosystems
- Interpret sustainable development as an economic challenge, not merely an ecological one
Quick Answer
Environmental Economics studies how human economic activity affects the natural environment and how policy can align private incentives with social well-being. In India — a country experiencing rapid industrialisation, a population of 1.4 billion, and growing climate vulnerability — these questions are especially urgent. The field covers pollution externalities, resource pricing, green accounting, and international climate agreements. Understanding it equips you to evaluate why markets alone under-provide clean air or clean water, what policy tools the government reaches for, and whether India's development path can remain sustainable over the long run.
Topics at a Glance
| Topic | What You Will Learn | Why It Matters |
|---|---|---|
| Pollution Control | Command-and-control rules vs. market-based tools like carbon taxes and cap-and-trade | India's air and water pollution impose enormous health and economic costs |
| Environmental Policies in India | NEP 1986, NDCs under Paris Agreement, Environment Protection Act | Laws shape what firms and farmers actually do |
| Sustainable Development | SDGs, intergenerational equity, India's poverty-environment nexus | Growth that destroys resources is self-defeating |
| Resource Management | Water, land, forest, and mineral allocation challenges in India | Scarcity of key resources constrains future growth |
| Climate Change Economics | Economic costs of warming, mitigation vs. adaptation, India's energy transition | India is among the most climate-vulnerable large economies |
| Green GDP | Adjusting GDP for environmental depletion and degradation | Conventional GDP overstates India's true economic progress |
Key Terms
| Term | Definition | Related Concept |
|---|---|---|
| Externality | A cost or benefit that falls on third parties not involved in a transaction — pollution is a negative externality | Pigovian tax, market failure |
| Pigovian Tax | A tax equal to the social cost of a negative externality, designed to make polluters pay the true price | Carbon tax, cap-and-trade |
| Cap-and-Trade | A system that sets a total emission limit and lets firms buy and sell permits within that cap | Pigovian tax, emission standards |
| Green GDP | GDP adjusted downward for the depletion of natural capital and environmental damage | Natural Resource Accounting, sustainable income |
| Sustainable Development | Development that meets present needs without compromising the ability of future generations to meet their own needs | Intergenerational equity, SDGs |
| NDC (Nationally Determined Contribution) | India's climate pledge under the Paris Agreement — targets for emission intensity and renewable energy | Paris Agreement, climate mitigation |
| Commons Tragedy | Over-exploitation of shared resources because no individual bears the full cost of depletion | Open-access resource, property rights |
| Environmental Impact Assessment (EIA) | Mandatory study of a project's likely ecological harm before government approval | Command-and-control, NEP |
| Carbon Sequestration | Absorption and storage of atmospheric CO₂, e.g., by forests or soils | Climate mitigation, agroforestry |
| Intergenerational Equity | Fairness across generations — present actions should not deprive future people of resources or a stable climate | Sustainable development, Green GDP |
