Pollution Control Economics — Prelims Strategy

Prelims Strategy

For Prelims, focus on conceptual clarity and India-specific examples. Master the definitions of key terms like externalities, Pigouvian tax, cap-and-trade, marginal abatement cost, and the Polluter Pays Principle.

Understand the core differences between market-based instruments and command-and-control regulations. Pay close attention to the specific features and functioning of Indian schemes such as PAT, NCAP, and the economic directives of the NGT.

Memorize the constitutional articles (48A, 51A(g)) and key environmental acts (EPA 1986, Water Act 1974, Air Act 1981) and their years. Landmark judgments like Vellore Citizens' Welfare Forum and M.C.

Mehta series are high-yield areas; know the principles they established. Current affairs related to green finance, carbon pricing, and international environmental agreements (like CBAM) are crucial. Practice MCQs that test both theoretical understanding and factual recall, especially those that involve identifying correct statements about policy mechanisms or distinguishing between similar concepts.

Look for trap options that confuse definitions or misattribute principles to cases.
